+2003-04-28 Tim Van Holder <tim.van.holder@pandora.be>
+
+ * data/yacc.c: (b4_lex_param): Corrected for the case where
+ %lex-param is provided and %pure-parser isn't.
+
+2003-04-27 Paul Eggert <eggert@twinsun.com>
+
+ Avoid gcc -Wundef warnings reported by Gerald Pfeifer in
+ <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00044.html>.
+ * data/yacc.c (YYSTACK_ALLOC): Don't evaluate YYSTACK_USE_ALLOCA
+ if it is not defined.
+ (YYMAXDEPTH): Don't evaluate YYMAXDEPTH if it is not defined.
+
+2003-04-26 Paul Eggert <eggert@twinsun.com>
+
+ * data/lalr1.cc (yy::Parser::pact_ninf_, yy::Parser::table_ninf_):
+ Declare to be of type suitable for the ninf value itself, not of
+ type suitable for the corresponding table, since the latter might
+ be unsigned but the ninf value might be negative. This fixes a
+ bug reported by Alexandre Duret-Lutz in
+ <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00017.html>.
+
+ * configure.ac (AC_FUNC_ERROR_AT_LINE): Remove, since gl_ERROR
+ invokes it. We shouldn't invoke it twice because it will attempt
+ to put error.o in the archive twice. This fixes a glitch reported
+ by Martin Mokrejs in
+ <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00041.html>.
+
+2003-04-21 Paul Eggert <eggert@twinsun.com>
+
+ * m4/error.m4: Update from Bruno Haible's 2003-04-14 patch
+ to gnulib.
+
+2003-04-21 Yakov Markovitch <Markovitch@iso.ru>
+
+ * data/glr.c (yyexpandGLRStack) [!YYSTACKEXPANDABLE]:
+ Fix obvious typo that results in uncompilable GLR parsers
+ when both %pure-parser and %locations are used. (trivial change)
+
+2003-04-17 Paul Eggert <eggert@twinsun.com>
+
+ * src/scan-gram.l: Add %option nounput, since we no longer use unput.
+ (unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
+ Do not insert the expected token via unput, as this runs afoul
+ of a POSIX-compatibility bug in flex 2.5.31.
+ All uses changed to BEGIN the parent state,
+ since we no longer insert the expected token via unput.
+ * tests/regression.at (Invalid inputs): Remove cascaded diagnostic
+ that is no longer emitted after the above change.
+
+ * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
+ the first one. This change is from Paul Hilfinger, and it fixes
+ regression reported by Werner Lemberg in
+ <http://mail.gnu.org/archive/html/bug-bison/2003-04/msg00026.html>.
+
+ (resolve_sr_conflict): Don't invoke state_errs_set
+ unless one or more tokens have been explicitly made errors.
+ Otherwise, the above change causes Bison to abort.
+
+ * tests/existing.at (GNU pic Grammar): New test case, taken from
+ Lemberg's email.
+
+2003-03-31 Akim Demaille <akim@epita.fr>

+
+ * .cvsignore: Add configure.lineno.

+ * doc/fdl.texi: Sync with latest FSF version.
+
+2003-03-12 Paul Eggert <eggert@twinsun.com>
+
+ * scan-gram.l (YY_USER_INIT): Initialize code_start, too.
+ (<INITIAL><<EOF>>, <SC_PRE_CODE><<EOF>>): Set *loc to the scanner
+ cursor, instead of leaving it undefined. This fixes a bug
+ reported by Tim Van Holder in
+ <http://mail.gnu.org/archive/html/bug-bison/2003-03/msg00023.html>.
+ * tests/input.at (Torturing the Scanner): Test the scanner on
+ an empty input file, which was Tim Van Holder's test case.
+
+ * m4/timevar.m4 (BISON_PREREQ_TIMEVAR): When checking whether
+ <sys/resource.h> can be included, include sys/time.h and
+ sys/times.h first, if available. This works around the SunOS
+ 4.1.4 porting bug reported by Bruce Becker in
+ <http://mail.gnu.org/archive/html/bug-bison/2003-03/msg00018.html>.
+
+ * m4/subpipe.m4 (BISON_PREREQ_SUBPIPE): Don't
+ AC_CHECK_HEADERS([sys/wait.h]), as this interferes with
+ AC_HEADER_SYS_WAIT.
+
+ Merge changes from gnulib. This was prompted because the CVS
+ snapshot didn't build on Solaris 7 due to strnlen problems.
+
+ These changes need to be merged back into gnulib:
+ * lib/hash.c: Include <stdbool.h> unconditionally.
+ * m4/onceonly.m4 (m4_quote): New macro.
+ (AC_CHECK_HEADERS_ONCE, AC_CHECK_FUNCS_ONCE, AC_CHECK_DECLS_ONCE):

+
+2003-03-02 Akim Demaille <akim@epita.fr>
+
+ * data/yacc.c, data/glr.c, data/lal1.cc: Use similar code to
+ generate verbose error messages.
+ Use the number of tokens as an upper bound in yytname, as it
+ cannot be a non terminal.
+
+2003-03-02 Akim Demaille <akim@epita.fr>
+
+ * tests/regression.at (_AT_DATA_DANCER_Y): Fix the expected error
+ message.
+
+2003-03-02 Akim Demaille <akim@epita.fr>
+
+ * tests/regression.at (_AT_DATA_DANCER_Y, AT_CHECK_DANCER): New.
+ Use them to exercise yycheck overrun.
+ Based on Andrew Suffield's grammar.
+
+2003-03-02 Akim Demaille <akim@epita.fr>
+
+ Create tests/local.at for Bison generic testing macros.
+
+ * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Move to...
+ * tests/local.at (AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS):
+ This new file.
+ * tests/calc.at (AT_CHECK_CALC): Adjust.
+ * tests/testsuite.at (AT_DATA_GRAMMAR_PROLOGUE, AT_DATA_GRAMMAR)
+ (AT_COMPILE, AT_COMPILE_CXX, AT_PARSER_CHECK): Move to...

+ Ignore the test if CXX is not functional.
+
+2003-03-01 Paul Eggert <eggert@twinsun.com>
+
+ * src/scan-gram.l (code_start): Initialize it to scanner_cursor,
+ not loc->end, since loc->end might contain garbage and this leads
+ to undefined behavior on some platforms.
+ (id_loc, token_start): Use (IF_LINTed) initial values that do not
+ depend on *loc, so that the reader doesn't give the the false
+ impression that *loc is initialized.
+ (<INITIAL>"%%"): Do not bother setting code_start, since its value
+ does not survive the return.
+
+2003-03-01 Akim Demaille <akim@epita.fr>
+
+ * src/scan-gram.l (code_start): Always initialize it when entering
+ into yylex, as SC_EPILOGUE is activated *before* the corresponding
+ yylex invocation. An alternative would be making it static, but
+ then it starts with the second %%'s beginning, instead of its end.
+
+2003-02-28 Paul Eggert <eggert@twinsun.com>
+
+ * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
+ around a UnixWare 7.1.1 porting bug reported by John Hughes in
+ <http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
+
+2003-02-26 Paul Eggert <eggert@twinsun.com>
+
+ * README: Mention compiler bug in Sun Forte Developer 6 update 2.
+ Remove Sequent/Pyramid discussion (nobody uses them any more).
+ Merge VMS and MS-DOS discussion; these ports may well be dead
+ but let's keep mentioning them for now. Put <> around email
+ addresses. Add copyright notice.
+
+2003-02-24 Paul Eggert <eggert@twinsun.com>
+

+
+2003-02-21 Akim Demaille <akim@epita.fr>
+
+ * doc/bison.texinfo: Use "location" consistently to refer to @n,

+ Suggested by Paul Eggert.
+
+2003-02-20 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc (position.hh): Make sure "columns" never pushes
+ before initial_columns.
+ (location.hh): Use consistent variable names when defining the
+ operator<<.
+ Use "last" so that we subtract from Positions, not from unsigned.
+
+2003-02-20 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc (position.hh): New subfile, including the extended
+ and Doxygen'ed documentation of class Position.
+ (location.hh): Use it.
+ Document a` la Doxygen.
+ With the help of Benoit Perrot.
+
+2003-02-20 Akim Demaille <akim@epita.fr>
+
+ * tests/calc.at (AT_CHECK_PUSHDEFS, AT_CHECK_POPDEFS): Define
+ AT_YACC_IF.
+ Redefine AT_YYERROR_SEES_LOC_IF using it.
+ (_AT_DATA_CALC_Y): Don't declare yyerror when lalr1.cc, as it is
+ not defined.
+ Don't use the location in yy::Parser::error_ and
+ yy::Parser::print_ when not %locations.
+ Activate more lalr1.cc tests.
+
+2003-02-19 Akim Demaille <akim@epita.fr>
+

+
+2003-02-19 Akim Demaille <akim@epita.fr>
+
+ * tests/calc.at (AT_CHECK_CALC): Check different scenarios of
+ error recovery, mixing with/without pops and discarding of the
+ lookahead.
+ Exercise YYERROR.
+ Disable the lalr1.cc tests as currently it doesn't support YYERROR.
+
+2003-02-17 Paul Eggert <eggert@twinsun.com>
+
+ * tests/atlocal.in (LDFLAGS, LIBS): New vars.
+ * tests/testsuite.at (AT_COMPILE): Use them.
+ This fixes the testsuite problem reported by Robert Lentz in
+ <http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00011.html>.
+
+2003-02-12 Paul Eggert <eggert@twinsun.com>
+
+ * data/yacc.c (yyerrlab) [YYERROR_VERBOSE]:

+ * data/glr.c (yyreportSyntaxError) [YYERROR_VERBOSE]: Likewise.
+ Check for malloc failure, for consistency with yacc.c.
+ (yytname_size): Remove, for consistency with yacc.c.

+ (operator<< (Position)): New.
+ (operator- (Position, int)): New.
+ (Location::first, Location::last): Rename as...

+ * tests/testsuite.at (AT_COMPILE_CXX): New.
+ * tests/calc.at (_AT_DATA_CALC_Y): Adjust yyerror to report the
+ locations in a more synthetic way.
+ (AT_CHECK_PUSHDEFS): AT_YYERROR_SEES_LOC_IF is positive if

+ Adjust the C locations to match those from Emacs: first column is

+ Change all the expected results.
+ Conform to the GCS: simplify the locations when applicable.
+ (LOC, VAL, YYLLOC_FORMAL, YYLLOC_ARG, USE_YYLLOC, LEX_FORMALS)

+
+2003-02-02 Akim Demaille <akim@epita.fr>

+
+ Version 1.875a.
+
+ * po/LINGUAS: Add ms.
+
+2003-01-30 Akim Demaille <akim@epita.fr>
+
+ * doc/Makefile.am (CLEANFILES): Add bison.fns for distcheck.
+
+2003-01-29 Paul Hilfinger <Hilfinger@CS.Berkeley.EDU>
+
+ * tests/cxx-type.at: Correct apparent typo in Bison input: $$ instead
+ of $1.
+
+ Changes in response to error report by S. Eken: GLR mode does not
+ handle negative $ indices or $ indices in embedded rules correctly.
+ See <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00076.html>.
+
+ * data/glr.c (b4_rhs_value): Change to use YYFILL macro.
+ (b4_rhs_location): Ditto.
+ (yyfill): New function to copy from stack tree into array
+ incrementally.
+ (yyuserAction): Modify to allow incremental move of semantic values
+ to rhs array when in GLR mode.
+ Define YYFILL to use in user-defined actions to fill semantic array
+ as needed.
+ Remove dummy use of yystack, as there is now a guaranteed use.
+ (yydoAction): Modify to allow incremental move of semantic values
+ to rhs array when in GLR mode.
+ (yyresolveAction): Ditto.
+ (yyglrShiftDefer): Update comment.
+ (yyresolveStates): Use X == NULL for pointers, not !X.
+ (yyglrReduce): Ditto.
+ (yydoAction): Ditto
+
+ * tests/glr-regr1.at: Rename to ...
+ * tests/glr-regression.at: Add new regression test for the problems
+ described above (adapted from S. Eken).
+ Update copyright notice.
+ * tests/testsuite.at: Rename glr-regr1.at to glr-regression.at.
+ * tests/Makefile.am: Ditto.
+
+2003-01-28 Paul Eggert <eggert@twinsun.com>
+
+ * data/lalr1.cc: Do not use @output_header_name@ unless
+ b4_defines_flag is set. This fixes two bugs reported by
+ Tim Van Holder in
+ <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00071.html>
+ and <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00073.html>.
+
+2003-01-21 Paul Eggert <eggert@twinsun.com>
+
+ * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
+ we don't need to worry about yyerrlab1 being reported as an
+ "unused label" by non-GCC C compilers. The downside is that if
+ locations are used then a couple of statements are duplicated each
+ time YYERROR is invoked, but the upside is that the warnings
+ should vanish.
+ (yyerrlab1): Move code to YERROR.
+ (yyerrlab2): Remove. Change uses back to yyerrlab1.
+ This reverts some of the 2002-12-27 change.
+
+2003-01-17 Paul Eggert <eggert@twinsun.com>
+
+ * src/output.c (symbol_printers_output): Fix typo that led
+ to core dump. Problem reported by Antonio Rus in
+ <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00058.html>.
+
+2003-01-13 Akim Demaille <akim@epita.fr>,
+ Quoc Peyrot <chojin@lrde.epita.fr>,
+ Robert Anisko <anisko_r@lrde.epita.fr>
+
+ * data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
+ when the stacks contain one element, as the loop would otherwise
+ free the last state, and then use the top state (the one we just
+ popped). This means that the initial elements will not be freed
+ explicitly, as is the case in yacc.c; it is not a problem, as
+ these elements have fake values.
+
+2003-01-11 Paul Eggert <eggert@twinsun.com>
+
+ * NEWS: %expect-violations are now just warnings, reverting
+ to Bison 1.30 and 1.75 behavior. This fixes the GCC 3.2
+ bootstrapping problem reported by Matthias Klose; see
+ <http://mail.gnu.org/archive/html/bug-bison/2003-01/msg00053.html>.
+ * src/conflicts.c (conflicts_print): Likewise.
+ * tests/conflicts.at (%expect not enough, %expect too much,
+ %expect with reduce conflicts): Likewise.
+ * doc/bison.texinfo (Expect Decl): Document this. Also mention
+ that the warning is enabled if the number of conflicts changes
+ (not necessarily increases).
+
+ * src/getargs.c (version): Update copyright year.
+
+2003-01-09 Akim Demaille <akim@epita.fr>
+
+ * src/Makefile.am, lib/Makefile.am: Use $(VAR) instead of @VAR@.
+
+2003-01-08 Paul Eggert <eggert@twinsun.com>
+

+ Fix a bug where error locations were not being recorded correctly.
+ This problem was originally reported by Paul Hilfinger in
+ <http://mail.gnu.org/archive/html/bug-bison/2002-11/msg00086.html>.
+
+ * data/yacc.c (yyparse): New local var yylerrsp, to record the
+ top of the location stack's error locations.
+ (yyerrlab): Set it. When discarding a token, push its location
+ onto yylerrsp so that we don't lose track of the error's end.
+ (yyerrlab1): Now is only the target of YYERROR, so that we can
+ properly record the location of the action that failed. For GCC
+ 2.93 and later, insert an __attribute__ ((__unused__)) to avoid
+ GCC warning about yyerrlab1 being unused if YYERROR is unused.
+ (yyerrlab2): New label, which yyerrlab now falls through to.
+ Compute the error's location by applying YYLLOC_DEFAULT to
+ the locations of all the symbols that went into the error.
+ * doc/bison.texinfo (Location Default Action): Mention that
+ YYLLOC_DEFAULT is also invoked for syntax errors.
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
+ Error locations include the locations of all the tokens that were
+ discarded, not just the last token.
+
+2002-12-26 Paul Eggert <eggert@twinsun.com>
+
+ * src/files.c: Include quote.h.
+ (compute_output_file_names): Warn if we detect conflicting
+ outputs to the same file. This should catch the misunderstanding
+ exemplified by Debian Bug 165349, reported by Bruce Stephens..
+
+ * src/conflicts.c (conflicts_print): If the user specifies
+ "%expect N", report an error if there are any reduce/reduce
+ conflicts. This is what the manual says should happen.
+ This fixes Debian bug 130890, reported by Anthony DeRobertis.
+ * tests/conflicts.at (%expect with reduce conflicts): New test.
+
+ Don't use m4_include on relative file names, as it doesn't work as
+ desired if there happens to be a file with that name under ".".
+
+ * m4sugar/version.m4: Remove; it was included but it wasn't used.
+ * data/Makefile.am (dist_m4sugar_DATA): Remove m4sugar/version.m4.
+ * data/m4sugar/m4sugar.m4: Don't include m4sugar/version.m4.
+ * data/glr.c, data/lalr1.cc, data/yacc.c: Don't include c.m4.
+ * src/output.c (output_skeleton): Use full path names when
+ specifying a file to include; don't rely on include path, as
+ it's unreliable when the working file contains a file with
+ that name.
+
+2002-12-25 Paul Eggert <eggert@twinsun.com>

+
+ * src/parse-gram.y (declaration): Use enum "report_states" rather
+ than its numeric value 1.
+
+ * src/scan-skel.l ("@output ".*\n): Close any old yyout before

+
+2002-12-24 Paul Eggert <eggert@twinsun.com>
+
+ Version 1.75e.
+
+ * Makefile.maint (cvs-update): Don't assume that the shell

+ nonterminals at the end, since it didn't change the result.
+
+2002-12-24 Paul Eggert <eggert@twinsun.com>
+
+ If the user does not define YYSTYPE as a macro, Bison now declares it
+ using typedef instead of defining it as a macro. POSIX requires this.
+ For consistency, YYLTYPE is also declared instead of defined.
+
+ %union directives can now have a tag before the `{', e.g., the
+ directive `%union foo {...}' now generates the C code
+ `typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
+ The default union tag is `YYSTYPE', for compatibility with Solaris 9
+ Yacc. For consistency, YYLTYPE's struct tag is now `YYLTYPE'
+ instead of `yyltype'.
+
+ `yystype' and `yyltype' are now obsolescent macros instead of being
+ typedefs or tags; they are no longer documented and will be
+ withdrawn in a future release.
+
+ * data/glr.c (b4_location_type): Remove.
+ (YYSTYPE): Renamed from yystype.
+ (YYSTYPE_IS_DECLARED): New macro, used to prevent double-typedef.
+ (struct YYLTYPE): Renamed from struct yyltype.
+ (YYLTYPE): Renamed from yyltype.
+ (yyltype, yystype): New (and obsolescent) macros,
+ for backward compatibility.
+ * data/yacc.c: Likewise.
+
+ * data/yacc.c (YYSTYPE): Declare as union YYSTYPE if the user
+ does not specify a union tag. This is for compatibility with
+ Solaris 9 yacc.
+
+ * src/parse-gram.y (add_param): 2nd arg is now char * not char
+ const *, since it is now modified by stripping surrounding { }.
+ (current_braced_code): Remove.
+ (PERCENT_DESTRUCTOR, PERCENT_PRINTER, PERCENT_UNION,
+ PERCENT_LEX_PARAM, PERCENT_PARSE_PARAM): Change names to include
+ trailing " {...}". Now of type <chars>.
+ (grammar_declaration): Adjust to bundled tokens.
+ (code_content): Remove; stripping is now done by add_param.
+ (print_token_value): Print contents of bundled tokens.
+ (token_name): New function.
+
+ * src/reader.h (braced_code, current_braced_code): Remove.
+ (token_name): New decl.
+
+ * src/scan-gram.l (handle_dollar, handle_at): Now takes int
+ token_type, not braced_code code_kind. All uses changed.
+ (SC_PRE_CODE): New state, for scanning after a keyword that
+ has (or usually has) an immediately-following braced code.
+ (token_type): New local var, to keep track of which token type
+ to return when scanning braced code.
+ (<INITIAL>"%destructor", <INITIAL>"%lex-param",
+ <INITIAL>"%parse-param", <INITIAL>"%printer",
+ <INITIAL>"%union"): Set token type and BEGIN SC_PRE_CODE
+ instead of returning a token type immediately.
+ (<INITIAL>"{"): Set token type.
+ (<SC_BRACED_CODE>"}"): Use it.
+ (handle_action_dollar, handle_action_at): Now returns bool
+ indicating success. Fail if ! current_rule; this prevents a core dump.
+ (handle_symbol_code_dollar, handle_symbol_code_at):
+ Remove; merge body into caller.
+ (handle_dollar, handle_at): Complain in invalid contexts.
+
