38 (Sync from coreutils.)
39 Work also when the working directory (with e.g. coreutils sources)
40 is version controlled with git, rather than CVS.
41 * bootstrap (CVS_only_file): Test for the existence of README-cvs,
42 rather than CVS.
43 In messages and comments, say e.g., "checked-out sources",
44 rather than "CVS sources".
45 (version_controlled_file): New function. Work for git as well as
46 for CVS. Don't use grep's -q option.
47 (slurp): Call it here, in place of CVS-specific code.

51 Fix testsuite for ./configure --enable-gcc-warnings:
52 * configure.ac (gcc-warnings): Move -Wall before -Wno-sign-compare.
53 Otherwise, gcc 4.1.0 (at least) warns about sign comparisons in
54 __AT_CHECK_PRINTER_AND_DESTRUCTOR in tests/actions.at.
55 * test/input.at (Torturing the Scanner): #include <stdlib.h> for abort.

96 * bootstrap (symlink_to_gnulib): Fix bug: the dot_dots shell
97 variable was sometimes used without being initialized. This
98 messed up the installation of the INSTALL file in some cases.
99
100 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
101
102 * bootstrap (usage, main program, symlink_to_gnulib): Add option
103 --copy. Inspired by a suggestion from Bruno Haible.
104
105 2006-10-03 Jim Meyering <jim@meyering.net>

108 sticks with the automake default in generating dependencies.

188 and try to make such failures easier to catch in the future.
189 * data/glr.c (YYTRANSLATE): Don't check for nonpositive arg;
190 that's now the caller's responsibility.
191 (yyprocessOneStack, yyrecoverSyntaxError, yyparse):
192 Set yychar = YYEOF if it's negative.

218 when all of the sources in a directory come from gnulib.

220 option that gnulib-tool adds to what becomes our lib/gnulib.mk.
221
222 2006-09-23 Jim Meyering <jim@meyering.net>

255
256 * bootstrap (symlink_to_gnulib): New function.
257 (cp_mark_as_generated): Use it, to prefer symlinks-to-gnulib
258 to copies-of-gnulib.
259 (cp_mark_as_generated, slurp, gnulib_files):
260 Avoid making a copy if it's the same as the old version.

282 (gl_INIT): Add
283 (GNULIB_AUTOCONF_SNIPPET): Remove.
284 (AM_GNU_GETTEXT): Add; require formatstring macros since that's
285 the pickiest.
286 * lib/.cvsignore: Add inttypes_.h.
287 * lib/Makefile.am: Include gnulib.mk first so we can append to it.
288 (AM_CFLAGS): Add WERROR_CFLAGS, to be more like coreutils.
289 (BUILT_SOURCES, EXTRA_DIST, MOSTLYCLEANFILES): Remove
290 no-longer-necessary initializations.
291 (lib_SOURCES): Remove, replacing by libbison_a_SOURCES.
292 * lib/subpipe.c: Include <unistd.h> unconditionally, now that we
293 use the unistd module.

297 gnulib-tool.m4, inttypes-h.m4, inttypes-pri.m4, inttypes.m4.
298 * src/Makefile.am (DEFS): Remove, since configmake does this for us.
299 (AM_CPPFLAGS): Remove -I../lib, since Automake does that for us.
300 * src/system.h: Include inttypes.h unconditionally, now that we
301 use the inttypes module. Don't bother to include stdint.h, since
302 inttypes.h now does that for us.
303 (LOCALEDIR): Remove, now that we use the configmake module.
304 * src/getargs.c: Include configmake.h.
305 * src/main.c: Likewise.
306 * src/output.c: Likewise.

312 <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
313
314 * src/parse-gram.y (symbol_declaration): Don't put statements
315 before declarations; it's not portable to C89.
316 * src/scan-code.l (handle_action_at): Likewise.
317
318 * src/scan-code.l: Always initialize braces_level; the old code
319 left it uninitialized and therefore had undefined behavior.
320
321 Don't attempt to redefine 'assert', since it runs afoul of
322 systems where standard headers (mistakenly) include <assert.h>.
323 Instead, define and use our own alternative, called 'aver'.
324 * src/reader.c: Don't include assert.h, since we no longer
325 use assert.
326 * src/scan-code.l: Likewise.
327 * src/system.h (assert): Remove, replacing with....
328 (aver): New function, taking a bool arg. All uses changed.

357 Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
358 runtime cost when YYDEBUG is not defined, and so that some tests
359 that used to fail now work. Problem and initial suggestion by
360 Paolo Bonzini.
361 * data/c++.m4 (b4_parse_param_cons): Omit leading ','.
362 * data/glr.cc (b4_parser_class_name):
363 Initialize yycdebug_ only if YYDEBUG. Also, initialize yydebug_.
364 (debug_level, set_debug_level): Affect yydebug_, not ::yydebug.
365 (yydebug_) [YYDEBUG]: New member.
366 (yycdebug_): Now defined only if YYDEBUG.
367 * data/lalr1.cc (yydebug_, yycdebug_): Now defined only if YYDEBUG.
368 (YYCDEBUG) [!YYDEBUG]: Don't use yydebug_ and yycdebug_.
369 (b4_parser_class_name): Initialize yydebug_ and yycdebug_ only
370 if YYYDEBUG.

372 Define only if YYDEBUG.
373 * tests/calc.at (_AT_DATA_CALC_Y) [!YYDEBUG]: Omit call to

381 * data/glr.cc (YYERROR_VERBOSE, YYTOKEN_TABLE): Remove.
382 We don't need them in glr.cc, and glr.c defines them.
383 Defining YYERROR_VERBOSE to 0 here breaks glr.c, since glr.c
384 assumes that defining it to anything is the same as defining
385 it to 1. Problem reported by Paolo Bonzini.

397 macros work. Problem reported by Michael Deutschmann in

399 * data/lalr1.cc: Likewise.

401 should be defined before any Bison declarations.
402 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Put defns
403 that depend on location.hh after, not before, Bison decls, since
404 we now include location.hh after the first user prologue.

423 and
424 <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00091.html>.

426 %destructor/%printer description.
427 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise.
428 * src/symlist.c (symbol_list_destructor_set, symbol_list_printer_set):
429 Invoke semantic_type_destructor_set or semantic_type_printer_set when a
430 list node contains a semantic type.
431 * src/symtab.c, src/symtab.h: Extend with a table that associates
432 semantic types with their %destructor's and %printer's.
433 (semantic_type_from_uniqstr, semantic_type_get,
434 semantic_type_destructor_set, semantic_type_printer_set): New functions
435 composing the public interface of that table.
436 (symbol_destructor_get, symbol_destructor_location_get,
437 symbol_printer_get, symbol_printer_location_get): If there's no
438 per-symbol %destructor/%printer, look up the per-type before trying
439 the default.

451 new per-type %destructor/%printer. Discussed at

458 a list in which each item is a symbol, semantic type, or

468 represent a semantic type or a %symbol-default in addition to just an
469 ordinary symbol. Add switched functions for setting %destructor's and
470 %printer's.
471 * tests/actions.at, tests/input.at: Add %symbol-default to all default
472 %destructor/%printer declarations.

476 Whether the default %destructor/%printer applies to a particular symbol
477 isn't a question of whether the user *declares* that symbol (in %token,
478 for example). It's a question of whether the user by any means
479 *defines* the symbol at all (by simply using a char token, for
480 example). $end is defined by Bison whereas any other token with token
481 number 0 is defined by the user. The error token is always defined by
482 Bison regardless of whether the user declares it with %token, but we
483 may one day let the user define error as a nonterminal instead.
484 * NEWS (2.3+): Say "user-defined" instead of "user-declared".
485 * doc/bison.texinfo (Freeing Discarded Symbols): Likewise, and document
486 the meaning of "user-defined".

492 * src/symtab.c (symbol_destructor_get, symbol_printer_get): In the
493 computation of whether to apply the default, don't maintain a list of
494 every Bison-defined symbol. Instead, just check for a first character
495 of '$', which a user symbol cannot have, and check for the error token.

527 commit: don't worry about complaints from symbols_pack.
528 * src/symtab.c (symbol_new, symbol_class_set,

530 each string literal as a new symbol and token, assign it a symbol
531 number, and don't complain about non-aliased string literals.
532 (symbols_pack): Since symbol_make_alias still does not decrement symbol

886 since stdint needs the former and wcwidth (which is now required
887 by mbswidth) needs the latter.

999 rule.

1004 all symbol declarations have been parsed.
1005 * src/scan-code.l (handle_action_dollar): Now that this is invoked
1006 after parsing the entire grammar file, the symbol list here in the case
1007 of a midrule is actually the midrule's empty RHS, so reference its
1008 parent rule's RHS where necessary.
1009 On the other hand, now that you can already know it's a midrule, you

1218 The Translation Project changed its way of publishing translations
1219 to maintainers. I haven't received any responses to my request
1220 for supporting the old way, or for documenting the new way. I
1221 have modified 'bootstrap' to use screen scraping
1222 (in this case, HTML scraping). This is unreliable and inelegant,
1223 but I don't see any better way. Yuck.
1224 * bootstrap (TP_URL, WGET_COMMAND): New vars.
1225 (get_translations): New function, which uses HTML scraping to
1226 deduce locations of latest translations.
1227 Use this function to grab both bison and bison-runtime .po files.
1228 Don't bother priming the pump for the runtime-po domain any more,
1229 as it's now translated better than bison is.

1998 Fix a longstanding bug uncovered by bro-0.9a9/src/parse.y, which I
1999 got from <http://bro-ids.org/download.html>. The bug is that
2000 when two actions appeared in succession, the second one was
2001 scanned before the first one was added to the grammar rule
2002 as a midrule action. Bison then output the incorrect warning
2003 "parse.y:905.17-906.36: warning: unused value: $3".
2004 * src/parse-gram.y (BRACED_CODE, action): These are no longer
2005 associated with a value.
2006 (rhs): Don't invoke grammar_current_rule_action_append.
2007 (action): Invoke it here instead.
2008 * src/reader.c (grammar_midrule_action): Now extern.
2009 (grammar_current_rule_action_append): Don't invoke
2010 grammar_midrule_action; that is now the scanner's job.
2011 * src/reader.h (last_string, last_braced_code_loc):
2012 (grammar_midrule_action): New decls.
2013 * src/scan-gram.l (last_string): Now extern, sigh.
2014 (last_braced_code_loc): New extern variable.
2015 (<INITIAL>"{"): Invoke grammar_midrule_action if the current
2016 rule already has an action.
2017 (<SC_BRACED_CODE>"}"): Set last_braced_code_loc before returning.
2018 * tests/input.at (AT_CHECK_UNUSED_VALUES):
2019 Add some tests to check that the above changes fixed the bug.

3555 * src/output.c: Include scan-skel.h.
3556 (scan_skel): Remove decl, since scan-skel.h does this.
3557 (output_skeleton):
3558 Indent calls to "error" to pacify "make maintainer-distcheck".

3574 "make maintainer-distcheck" complained about.

3603 the new runtime-po domain, prime the pump by extracting the
3604 relevant strings from the obsolete translations. This code can be
3605 removed once the bison-runtime domain has been translated by each
3606 team.

3635 the 2005-04-17 change, which is now accomplished (mostly) via
3636 changes in the parsers as described above.

3642 Fix more problems reported by twlevo@xs4all.nl.
3643 * tests/cxx-type.at: Don't pipe output of ./types through sed to
3644 remove trailing spaces. This loses the exit status of ./types,
3645 and isn't needed since ./types shouldn't be emitting trailing
3646 spaces.
3647 * data/glr.c (yyreturn): Don't pop stack if yyinitStateSet failed,
3648 as the stack isn't valid in that case.
3649
3650 * src/scan-gram.l (gram_get_lineno, gram_get_in, gram_get_out):
3651 (gram_get_leng, gram_get_text, gram_set_lineno, gram_set_in):
3652 (gram_set_out, gram_get_debug, gram_set_debug, gram_lex_destroy):
3653 Add declarations to pacify "gcc -Wmissing-prototypes" when flex 2.5.31
3654 is used.
3655 * src/scan-skel.l (skel_get_lineno, skel_get_in, skel_get_out):

3661 overly-picky compilers that reject 'char *foo = "bar";'.
3662
3663 * src/symtab.c (SYMBOL_ATTR_PRINT, symbol_print): Direct output
3664 to FILE * parameter, not to stderr. This fixes a typo introduced
3665 in the 2005-07-12 change.
3666
3667 * lib/subpipe.c (create_subpipe): Rewrite slightly to avoid
3668 warnings from GCC 4.

3681 * data/glr.c (yyrecoverSyntaxError): Don't bother to pop the
3682 stack before failing, as the cleanup code will do it for us now.
3683 * data/lalr1.cc (yyerrlab): Likewise.
3684 * data/glr.c (yyparse): Pop everything off the stack before
3685 freeing it, so that destructors get called properly.
3686 * data/lalr1.cc (yyreturn): Likewise.
3687 * data/yacc.c (yyreturn): Pop and destroy the start symbol, too.
3688 This is more consistent.
3689 * doc/bison.texinfo (Destructor Decl): Mention more reasons
3690 why destructors might be called. 1.875 -> 2.1.
3691 (Destructor Decl, Decl Summary, Table of Symbols):
3692 Some English-language cleanups for %destructor.
3693 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):

3702 (yyreportAmbiguity): "ambiguity detected" -> "syntax is ambiguous".
3703 (yyparse): Rename yyoverflowlab to yyexhaustedlab.
3704 * data/yacc.c (yyparse): "parser stack overflow" -> "memory exhausted".
3705 Rename yyoverflowab to yyexhaustedlab.
3706 When memory exhaustion occurs during syntax-error reporting,
3707 report it separately rather than in a single diagnostic; this
3708 eases translation.

3718 msgids; there's little point to having them translated, since they
3719 can be understood only by someone who can read the
3720 (English-language) source code.
3721
3722 Generate runtime-po/bison-runtime.pot automatically, so that we
3723 don't have to worry about garbage getting in that file. We'll
3724 make sure after the next official release that old msgids don't
3725 get lost. See
3726 <http://lists.gnu.org/archive/html/bison-patches/2005-07/msg00119.html>.
3727
3728 * runtime-po/Makefile.in.in, runtime-po/bison-runtime.pot: Remove.
3729 Now auto-generated.
3730 * PACKAGING: Don't claim that Gawk, GCC, Perl use this method yet.
3731 Fix typos in explanations of the runtime file.
3732 * bootstrap: Change gettext keyword from YYI18N to YY_.
3733 Use standard Makefile.in.in in runtime-po, since we'll arrange
3734 for backward-compatible bison-runtime.po files in a different way.
3735 * data/glr.c (YY_): New macro, from yacc.c.
3736 (yyuserAction, yyreportAmbiguity, yyreportSyntaxError, yyparse):
3737 Translate messages intended for users.
3738 (yyreportSyntaxError): Change "virtual memory" to "memory" to match
3739 the wording in the other skeletons. We don't know that the memory
3740 is virtual.
3741 * data/lalr1.cc (YY_): Renamed from _. All uses changed.
3742 Use same method that yacc.c uses.
3743 Don't translate debugging messages.
3744 (yy::yyreport_syntax_error): Put in a FIXME for the i18n stuff;
3745 it doesn't work (yet), and requires C++ expertise to fix.
3746 * data/yacc.c (YY_): Renamed from YY18N. All uses changed.
3747 Move defn to a more logical place, to be consistent with other
3748 skeletons.
3749 Don't translate debugging messages.
3750 Don't assume line numbers fit in unsigned int; use unsigned long fmts.
3751 * doc/bison.texinfo: Mention <libintl.h>. Change glibc cross reference
3752 to gettext cross reference. Add indexing terms. Mention YYENABLE_NLS.
3753 * runtime-po/POTFILES.in: Add data/glr.c, data/lalr1.cc.

3769 (YYCHK1): Use goto (a la yacc.c) rather than setting a flag.
3770 (yyparse): New local variable yyresult to record the result.

3772 struct.

3776 if YYABORT is used).

3939 not GNU M4, and that it works with any POSIX-compatible Awk.
3940 * examples/calc++/Makefile.am (run_extexi): Remove; not used.
3941 ($(calc_extracted)): Renamed from $(calc_sources_extracted),
3942 so that we also get calc++-parser.yy. Geneate it.
3943 Use $(AWK), not gawk, since any conforming Awk will do.
3944 Put comment before action, since older 'make' can't handle comment
3945 in action.

3950 of target. (This had a shell syntax error anyway; a stray "x".)

3972 never had any % directives, we can simply pass it to yyerror.
3973 (yyparse): Use "t a; a=b;" rather than "t a = b;" when a will
3974 be modified later, as that is the usual style in glr.c.

3983 (struct yyGLRStack.yyspaceLeft): Now size_t, not int.
3984 (yyinitGLRStack, yyfreeGLRstack): Remove unnecessary forward decls,
3985 so that we don't have to maintain their signatures.
3986 (yyFail): Check for buffer overflow, by using vsnprintf rather
3987 than vsprintf. Allocate a bigger buffer if possible.
3988 Report an error if buffer allocation fails.
3989 (yyStackOverflow): New function.
3990 (yyinitStateSet, yyinitGLRStack): Return a boolean indicating whether
3991 the initialization was successful. It might fail if storage was
3992 exhausted.
3993 (yyexpandGLRStack): Add more checks for storage allocation failure.
3994 Use yyStackOverflow to report failures.

4000 can print diagnostics on storage allocation failure. All callers
4001 changed.
4002 (yyresolveValue): Use yybool for boolean.
4003 (yyreportSyntaxError): Check for size-calculation overflow.
4004 This code is taken from yacc.c.

4006 the initial stack.

4549 Remove uses of 'short int' and 'unsigned short int'. This raises
4550 some arbitrary limits. It uses more memory but nowadays that's
4551 not much of an issue.
4552
4553 This change does not affect the generated parsers; that's a different
4554 task, as some users will want to conserve memory there.
4555
4556 Ideally we should use size_t to represent all object counts, and

4716 the normal case and one for the error case. Just use the
4717 first one uniformly. Problem reported by Frank Heckenbach.
4718 (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
4719 use exactly the same macro in both places.

4721 so that the normal-case YYRHSLOC works for the error case too.

4726 we have an array of locations. Use the same macro for both glr

4810 (build_relations): Initialize includes[i] in all cases.
4811 * src/reader.c (packgram): Always initialize rules[ruleno].prec
4812 and rules[ruleno].precsym. Initialize members in order.

4957 In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
4958 whether the reducion was empty or not. This leaves room to
4959 improve the use of YYLLOC_DEFAULT in such a case.
4960 lalr1.cc is still experimental, so changing this is acceptable.
4961 And finally, there are probably not many users who changed the
4962 handling of locations in GLR, so changing is admissible too.
4963
4964 * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an

5109 macro, so that these directives are passed to
5110 AT_BISON_OPTION_PUSHDEFS to get correct help macros.
5111 Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
5112 Move the AT_SETUP/AT_CLEANUP outside, to report as test title
5113 the extra Bison directives instead of the whole series.
5114 Change the grammar so that there are recoverable errors, and
5115 unrecoverable errors. Now we can have the parser give up before
5116 consuming the whole input. As a result we now can observe that
5117 the lookahead is freed when needed.
5118 Change the parser source to parse argv[1] instead of a hard coded
5119 string.
5120 Simplify yylex, and give a value and location to EOF.
5121 Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
5122 passed directives already coded in the file.
5123 Add some tests to check the location of "error".
5124 For some tests, the C++ parser is correct, and not yacc.c.
5125 For other tests, they provide different, but unsatisfying, values,
5126 so keep the C++ value so that at least one parser is "correct"
5127 according to the test suite.
5128 (Actions after errors): Remove, this is subsumed by the
5129 AT_CHECK_PRINTER_AND_DESTRUCTOR series.

5307 Spent a few hours checking out which prerequisite versions the

5309 Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
5310 a seemingly endless set of combinations of versions more recent
5311 than that. The bottom line is that the current sources require
5312 fairly recent versions of the build tools, and it'll be some work

5549 change.

5579 test whether it can stand alone.
5580
5581 * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Don't
5582 declare yyerror when using lalr.cc, as GCC 3.4.0 warns about the
5583 unused declaration.
5584
5585 * tests/synclines.at (%union synch line): Put a dummy member in

5829 When reducing initial empty rules, Bison parser read an initial
5830 location that is not defined. This results in garbage, and that

5878 lalr1.cc and yacc.c.
5879 (YYERROR): Goto to yyerrorlab, not yyerrlab1.
5880 (yyerrlab1): Remove, but where it used to be (now the bottom part of
5881 yyerrlab), when hitting EOF, pop the whole stack here instead of
5882 merely falling thru the default error handling mechanism.
5883 (yyerrorlab): New label, with the old contents of YYERROR,
5884 plus the following change: pop the stack of rhs corresponding
5885 to the production that invoked YYERROR. That is how Yacc
5886 behaves (required by POSIX).

6128 The problem was that GLR parsers did not conform to the C standard,
6129 because actions like { $1 = $2 + $3; } expanded to expressions
6130 that invoked YYFILL in separate subexpressions, and YYFILL assigned
6131 to a local variable. The C standard says that expressions
6132 like (var = f ()) + (var = f ()) have undefined behavior.
6133 Another problem was that GCC sometimes issues warnings that
6134 yyfill and its parameters are unused.
6135
6136 * data/glr.c (yyfillin): Renamed from the old yyfill. Mark
6137 as possibly unused.
6138 (yyfill): New function.
6139 (YYFILL): Use it.
6140 (yyuserAction): Change type of yynormal to bool, so that it matches
6141 the new yyfill signature. Mark it as possibly unused.
6142
6143
6144 Follow up on a bug I reported in February, where a Bison-generated
6145 parser can loop. Provide a test case and a fix for yacc.c. I
6146 don't have a fix for lalr1.cc or for glr.c, unfortunately.
6147 The original bug report is in:

6150 * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
6151 macro's size was becoming unwieldy.
6152 (yyerrlab): Do not discard an empty lookahead symbol, as this
6153 might destroy garbage.
6154 (yyerrorlab): New label, with the old contents of YYERROR,
6155 plus the following change: pop the stack of rhs corresponding
6156 to the production that invoked YYERROR. That is how Yacc
6157 behaves, and POSIX requires this behavior.
6158 (yyerrlab1): Use YYPOPSTACK instead of its definiens.
6159 * tests/calc.at (_AT_DATA_CALC_Y): Include unistd.h if available.
6160 Define 'alarm' to do nothing if unistd.h is not available.
6161 Add a new rule "exp: '-' error;" to test the above change to
6162 data/yacc.c. Use 'alarm' to abort any test taking longer than
6163 10 seconds, as it's probably looping.
6164 (AT_CHECK_CALC): Test recovery from error in new grammar rule.
6165 Also, the new yacc.c generates two fewer diagnostics for an
6166 existing test.

6794 we don't need to worry about yyerrlab1 being reported as an

6815 free the last state, and then use the top state (the one we just
6816 popped). This means that the initial elements will not be freed
6817 explicitly, as is the case in yacc.c; it is not a problem, as
6818 these elements have fake values.

6931 'conflict_report'. Translate the entire conflict report at once,
6932 so that we don't assume that "," has the same interpretation in
6933 all languages.
6934 (conflicts_output): Use Yacc-style conflict report for each state,
6935 instead of our more-complicated style.
6936 (conflicts_print): Use Yacc-style conflict report, except print
6937 the input file name when not emulating Yacc.

6955 * data/yacc.c (yyparse): New local var yylerrsp, to record the
6956 top of the location stack's error locations.
6957 (yyerrlab): Set it. When discarding a token, push its location
6958 onto yylerrsp so that we don't lose track of the error's end.
6959 (yyerrlab1): Now is only the target of YYERROR, so that we can
6960 properly record the location of the action that failed. For GCC
6961 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
6962 GCC warning about yyerrlab1 being unused if YYERROR is unused.
6963 (yyerrlab2): New label, which yyerrlab now falls through to.
6964 Compute the error's location by applying YYLLOC_DEFAULT to

7027 If the user does not define YYSTYPE as a macro, Bison now declares it
7028 using typedef instead of defining it as a macro. POSIX requires this.
7029 For consistency, YYLTYPE is also declared instead of defined.
7030
7031 %union directives can now have a tag before the `{', e.g., the
7032 directive `%union foo {...}' now generates the C code
7033 `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
7034 The default union tag is `YYSTYPE', for compatibility with Solaris 9
7035 Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
7036 instead of `yyltype'.
7037
7038 `yystype' and `yyltype' are now obsolescent macros instead of being
7039 typedefs or tags; they are no longer documented and will be
7040 withdrawn in a future release.

7047 (yyltype, yystype): New (and obsolescent) macros,
7048 for backward compatibility.
7049 * data/yacc.c: Likewise.
7050
7051 * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
7052 does not specify a union tag. This is for compatibility with
7053 Solaris 9 yacc.

7072 has (or usually has) an immediately-following braced code.

7074 to return when scanning braced code.

7144 Remove unportable casts and storage allocation tricks.

7219 too much storage.

8447

8822 Let nondeterministic skeletons be usable with deterministic
8823 tables.
8824
8825 With the patch, GAWK compiled by GCC without -O2 passes its test
8826 suite using a GLR parser driven by LALR tables. It fails with -O2
8827 because `struct stat' gives two different answers on my machine:
8828 88 (definition of an auto var) and later 96 (memset on this var).
8829 Hence the stack is badly corrumpted. The headers inclusion is to
8830 blame: if I move the awk.h inclusion before GLR's system header

8948 * lib/abitset.c (abitset_bytes): Return a size that is aligned
8949 properly for vectors of objects. Do not assume that adding a
8950 header size to a multiple of a word size yields a value that is
8951 properly aligned for the whole union.
8952 * lib/bitsetv.c (bitsetv_alloc): Likewise.
8953
8954 * lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
8955 unique names for structures.

8988 All instances of parameters of type enum bitset_opts are now of
8989 type enum_bitset_opts, to conform to the C Standard, and similarly
8990 for enum_bitset_type.

8992 * lib/lbitset.c (enum_lbitset_find_mode): Likewise.
8993
8994 Do not use "struct bitset_struct" to mean different things in
8995 different modules. Not only is this confusing, it violates
8996 the C Standard, which requires that structure types in different
8997 modules must be compatible if one is to be passed to the other.
8998 * lib/bbitset.h (bitset): Now points to a union, not to a struct.
8999 All instances of "struct bitset_struct *" replaced with "bitset".

9004 etc.

9012 Likewise.

9014 Do not call a function of type T using a call that assumes the
9015 function is of a different type U. Standard C requires that a
9016 function must be called with a type that is compatible with its
9017 definition.
9018 * lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
9019 New decls.

9303 (yyreportParseError): Use size_t for yysize.
9304 (yy_yypstack): No longer nested inside yypstates, as nested
9305 functions are not portable. Do not assume size_t is the
9306 same width as int.
9307 (yypstates): Do not assume that ptrdiff_t is the same width
9308 as int, and similarly for yyposn and YYINDEX.
9309
9310 * data/yacc.c: Fix comment about `$$ = $1': it can copy garbage.
9311
9312 * lib/Makefile.am (INCLUDES): Do not include from the intl
9313 directory, which has been removed.
9314 * src/Makefile.am (INCLUDES): Likewise.

9348
9349 * lib/obstack.c, lib/obstack.h: Sync with fileutils, except use
9350 PROTOTYPES to check for prototypes, and "defined __STDC__" to
9351 check for void *.
9352
9353 * lib/bbitset.h (BITSET_WORD_BITS): Now of type unsigned, not
9354 size_t; the old version tried to do this but casted improperly.
9355 (bitset_bindex, bitset_windex): Now size_t, not unsigned long.
9356 (bitset_test): Now returns int, not unsigned long.
9357

9359 (_): New macro.
9360 (bitset_stats_set, bitset_stats_reset, bitset_stats_test): Don't
9361 name locals "index", as it generates unnecessary warnings on some
9362 hosts that have an "index" function.
9363
9364 * lib/bitset_stats.c (bitset_stats_print_1, bitset_stats_print,
9365 bitset_stats_read, bitset_stats_write): Wrap strings in _() if

9386 src/main.c, src/relation.c, src/state.c, lib/bitset_stats.c,
9387 lib/timevar.c.
9388 Use src/parse-gram.y instead of src/parse-gram.c, as the gettext
9389 manual recommends.
9390 Similarly, use src/scan-gram.l instead of src/scan-gram.c.
9391
9392 * src/complain.c (strerror_r): Remove decl; not needed.
9393 (strerror): Use same pattern as ../lib/error.c.
9394
9395 * src/files.c, src/files.h (compute_header_macro): Remove; unused.
9396
9397 * src/gram.c (grammar_dump): Do not assume ptrdiff_t fits in int.
9398
9399 * src/main.c (main): Cast result of bindtextdomain and textdomain
9400 to void, to avoid a GCC warning when --disable-nls is in effect.
9401
9402 * src/scan-gram.l: Use strings rather than escapes when possible,
9403 to minimize the number of warnings from xgettext.
9404 (handle_action_dollar, handle_action_at): Don't use isdigit,
9405 as it mishandles negative chars and it may not work as expected
9406 outside the C locale.
9407
9408 * src/symtab.c (symbol_get): Don't cast LHS of an assignment;
9409 this is a GCC extension and is not portable to other compilers.
9410
9411 * src/system.h (alloca): Use same pattern as ../lib/error.c.
9412 Do not include <ctype.h>; no longer needed.
9413 Do not include <malloc.h>; no longer needed (and generates
9414 warnings on OpenBSD 3.0).
9415
9416 * tests/cxx-type.at (yylex): Do not pass signed char to isupper;
9417 it's not portable.
9418
9419 * tests/regression.at: Do not use 'cc -c input.c -o input';
9420 Sun C rejects this. Instead, use 'cc -c input.c -o input.o'.
9421
9422 * tests/synclines.at (AC_SYNCLINES_COMPILE): Accept any nonzero
9423 exit status as failure, not just exit status 1. Sun C exits
9424 with status 2 sometimes.
9425
9426 * tests/torture.at (AT_INCREASE_DATA_SIZE): New macro.
9427 Use it for the two large tests.

9454 `lookaheads_rule' member.
9455 (reductions_t): Add a `lookaheads' member.

9484 pointers, instead of their numbers.

9486 as they were lo longer used.

9591 different: save its reduction (accept) instead of having a state

9593 Note: the final state is now a ``regular'' state, i.e., the
9594 parsers now contain `reduce 0' as default reduction.
9595 Nevertheless, since they decide to `accept' when yystate =

11371 hard coded 2.
11372 (Even though this 2 is not the same as above: the number of the
11373 undeftoken remains being 2, it is its user token number which
11374 might not be 2).

11419 passes, but produces negative #line number, once fixed, GCC is
11420 killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of

12605 these states are automatically computed from the initial state.
12606 (generate_states): Adjust.
12607 * src/print.c: When reporting a rule number to the user, substract
12608 1, so that the axiom rule is rule 0, and the first user rule is 1.
12609 * src/reduce.c: Likewise.
12610 * src/print_graph.c (print_core): For the time being, just as for
12611 the report, depend upon --trace-flags to dump the full set of

12613 * src/reader.c (readgram): Once the grammar read, insert the rule
12614 0: `$axiom: START-SYMBOL $'.
12615 * tests/set.at: Adjust: rule 0 is now displayed, and since the
12616 number of the states has changed (the final state is no longer
12617 necessarily the last), catch up.

12640 * src/reader.c (eoftoken): New.
12641 (parse_token_decl): If the token being defined has value `0', it
12642 is the eoftoken.
12643 (packsymbols): No longer hack `tags' to insert `$' by hand.
12644 Be sure to preserve the value of the eoftoken.
12645 (reader): Make sure eoftoken is defined.
12646 Initialize nsyms to 0: now eoftoken is created just like the others.
12647 * src/print.c (print_grammar): Don't special case the eof token.
12648 * src/regression.at: Adjust: `$' has value 0, not -1, which was a
12649 lie anyway, albeit pleasant.
12650 * tests/calc.at: Exercise error messages with eoftoken.
12651 Change the grammar so that empty input is invalid.

13081 but that's to be addressed elsewhere.
13082 No longer output the rule numbers, but do output the state number.

13656 faster and reduces fragmentation.

13658 Do not limit the number of items in the stack to a value that fits
13659 in 'int', as this is an arbitrary limit on hosts with 64-bit
13660 size_t and 32-bit int.

15888 The location tracking mechanism is precious for parse error
15889 messages. Nevertheless, it is enabled only when `@n' is used in

15924 Test also `--verbose', `--defines' and `--name-prefix'. Testing
15925 the latter demonstrates a flaw in the handling of non debugging
15926 parsers introduced by myself on 2000-03-16: `#define yydebug 0'
15927 was used in order to simplify:
15928
15929 #if YYDEBUG

15938 if (yydebug)
15939 {
15940 ...
15941 }

15995 Use the more standard files `xalloc.h' and `xmalloc.c' instead of
15996 Bison's `allocate.c' and `alloc.h'. This patch was surprisingly
15997 difficult and introduced a lot of core dump. It turns out that
15998 Bison used an implementation of `xmalloc' based on `calloc', and
15999 at various places it does depend upon the initialization to 0. I
16000 have not tried to isolate the pertinent places, and all the former
16001 calls to Bison's `xmalloc' are now using `XCALLOC'. Someday,

17090 declaration to allow a multi-character symbol as an alias.
17091 (parse_thong_decl): New function.

17102 Revised and use multiple warnxxx functions to avoid using VARARGS1.
17103 (read_declarations): Improve the error message for
17104 an invalid character. Do not abort.

17132 (lex): Use literalchar.
17133 (lex): Implemented "..." tokens.
17134 (literalchar, lex, parse_percent_token): Made tokenbuffer
17135 always contain the token. This includes growing the token
17136 buffer while reading an integer.
17137 (parse_percent_token): Replaced if-else statement with percent_table.
17138 (parse_percent_token): Added % declarations as another
17139 way to specify the flags -n, -l, and -r. Also added hooks for
17140 -d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
17141 major changes to files.c.
17142 (lex) Retain in the incoming stream a character following
17143 an incorrect '/'.
17144 (skip_white_space, lex): Revised most error messages
