+2004-12-12 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/glr.c (YYRHSLOC): Don't have two definitions, one for
+ the normal case and one for the error case. Just use the
+ first one uniformly. Problem reported by Frank Heckenbach.
+ (YYLLOC_DEFAULT): Use the conventions of yacc.c, so we can
+ use exactly the same macro in both places.
+ (yyerror_range): Now of type yyGLRStackItem, not YYLTYPE,
+ so that the normal-case YYRHSLOC works for the error case too.
+ All uses changed.
+ * data/yacc.c (YYRHSLOC): New macro, taken from glr.c.
+ (YYLLOC_DEFAULT): Use the same macro as glr.c.
+ * doc/bison.texinfo (Location Default Action): Don't claim that
+ we have an array of locations. Use the same macro for both glr
+ and lalr parsers. Mention YYRHSLOC. Mention what happens when
+ the index is 0.

+
+ * src/relation.h (relation_print, relation_digraph):

+ * src/relation.c: Likewise.
+ (top, infinity): Now of type relation_node, not int.

+
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
+ specifying whether the test should be skipped. Use it tp
+ specify that the [%defines %skeleton "lalr1.cc"] tests currently
+ fail on some hosts, and should be skipped.
+
+2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/system.h (CALLOC, MALLOC, REALLOC): Remove. All callers
+ changed to use xcalloc, xnmalloc, xnrealloc, respectively,
+ unless otherwise specified below.
+
+ * src/LR0.c (allocate_itemsets): Use xnmalloc, not xcalloc,

+ conflict_list[0] was always 0, but now it isn't initialized.
+
+ * src/table.c (table_grow): When conflict_table grew, the grown

+
+ * src/lalr.h (GOTO_NUMBER_MAXIMUM): New macro.
+ * src/lalr.c (set_goto_map): Don't allow ngotos to equal

+ Introduce another definition to address simple location arrays.
+ (yyGLRStack): New member: yyerror_range.
+ (yyrecoverSyntaxError, yyparse): Update it.

+ * tests/cxx-type.at (_AT_TEST_GLR_CXXTYPES): Change its yylex so
+ that column numbers start at column 0, as per GNU Coding
+ Standards, the others tests, and the doc.
+ (_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT_WITH_LOC):
+ Adjust to the above change (first column is 0).
+ And adjust the location of the "<error>", now covering the whole
+ line.
+
+2004-10-22 Akim Demaille <akim@epita.fr>
+ and Paul Eggert <eggert@cs.ucla.edu>
+
+ Remove some arbitrary limits on goto numbers and relations.
+ * src/lalr.c (goto_map, ngotos, from_state, to_state): Omit
+ initial values, since they're never used.
+ (set_goto_map): ngotos is now unsigned, so test for overflow
+ by seeing whether it wraps around to zero.
+ * src/lalr.h (goto_number): Now size_t, not short int.
+ (GOTO_NUMBER_MAXIMUM): Remove.
+ * src/relation.c (relation_print, traverse, relation_transpose):

+
+2004-10-22 Paul Eggert <eggert@cs.ucla.edu>
+
+ * doc/bison.texinfo (Language and Grammar): In example, "int" is a

+ <http://lists.gnu.org/archive/html/bug-bison/2004-10/msg00017.html>.
+
+2004-10-11 Akim Demaille <akim@epita.fr>
+
+ * src/symtab.c (symbol_check_alias_consistency): Also check

+ Reported by Alexandre Duret-Lutz.
+ Recode the handling of associativity and precedence in terms

+ Accept no redeclaration at all, not even equal to the previous

+ (redeclaration): New.
+ Use it to factor redeclaration complaints.
+ (symbol_make_alias): Don't set the type of the alias, let

+
+2004-10-09 Paul Eggert <eggert@cs.ucla.edu>

+2004-10-06 Akim Demaille <akim@epita.fr>
+
+ * src/parse-gram.y (add_param): Fix the truncation of trailing
+ spaces.
+
+2004-10-05 Akim Demaille <akim@epita.fr>
+
+ In Bison 1.875's yacc.c, YYLLOC_DEFAULT was called regardless
+ whether the reducion was empty or not. This leaves room to
+ improve the use of YYLLOC_DEFAULT in such a case.
+ lalr1.cc is still experimental, so changing this is acceptable.
+ And finally, there are probably not many users who changed the
+ handling of locations in GLR, so changing is admissible too.
+
+ * data/glr.c, data/lalr1.cc, data/yacc.c (YYLLOC_DEFAULT): On an
+ empty reduction, set @$ to an empty location ending the previously
+ stacked symbol.
+ Adjust uses to make sure the code is triggered on empty
+ reductions.
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust the
+ expected output: empty reductions have empty locations.
+
+2004-09-29 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc: Move towards a more standard C++ coding style
+ for templates: Class < T > -> Class<T>.
+
+2004-09-29 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc: Reinstall the former ctor, for sake of
+ compatibility, but warn it will be removed.
+ Move towards a more standard C++ coding style (i.e., type *var ->
+ type* var).
+
+2004-09-27 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/parse-gram.y (add_param): Rewrite to avoid strchr,
+ since it's less likely to work if NULs are involved in the future.
+
+2004-09-27 Akim Demaille <akim@epita.fr>
+
+ * data/yacc.c (YY_LOCATION_PRINT): Fix its default declaration.

+
+ * data/lalr1.cc (b4_parse_param_decl_1): New.

+2004-09-24 Akim Demaille <akim@epita.fr>
+
+ * src/parse-gram.y (add_param): Strip the leading and trailing

+
+2004-09-24 Akim Demaille <akim@epita.fr>
+

+
+2004-09-21 Akim Demaille <akim@epita.fr>
+
+ * data/yacc.c, data/glr.c (b4_at_dollar, b4_dollar_dollar): Remove
+ the useless parentheses.
+ Suggested by Paul Eggert.
+
+2004-09-20 Akim Demaille <akim@epita.fr>
+
+ Let the initial-action act on the look-ahead, and use it for the
+ "initial push" (corresponding to an hypothetical beginning-of-file).
+ And let lalr1.cc honor %initial-action.
+
+ * doc/bison.texinfo (Initial Action Decl): Clarify, and add an
+ example.
+ * data/lalr1.cc (Parser::initlocation_): Remove, bad experiment.
+ (Parser::Parser): Remove the ctor that used to initialize it.
+ (Parser::parse): Like in the other skeletons, issue the "starting
+ parse" message before any action.
+ Honor %initial-action.
+ Initialize the stacks with the lookahead.
+ * data/yacc.c: Let $$ and @$ in %initial-action designate the
+ look-ahead.
+ Push them in the stacks.
+ * tests/actions.at, tests/calc.at: Adjust the C++ ctor invocations.
+
+2004-09-20 Akim Demaille <akim@epita.fr>
+
+ * doc/bison.texinfo (Initial Action Decl): New.
+
+2004-09-20 Akim Demaille <akim@epita.fr>
+
+ * data/yacc.c (YY_LOCATION_PRINT): Use YYLTYPE_IS_TRIVIAL as a
+ clearer criterion to define it.
+ (parse): Initialize the initial location when YYLTYPE_IS_TRIVIAL.
+ When reducing on an empty RHS, use the latest stacked location as
+ location.
+ yylloc is not always available.
+ * data/glr.c: Likewise.
+ Also, honor initial-actions.
+
+2004-09-20 Akim Demaille <akim@epita.fr>
+
+ * data/yacc.c (YY_LOCATION_PRINT): New.
+ Define when we know YYLTYPE's structure, i.e., when the default
+ YYLLOC_DEFAULT is used.
+ * data/c.m4 (b4_yysymprint_generate): Use it.
+ * data/lalr1.cc (YYLLOC_DEFAULT): Stop relying on the initial
+ value of the result.
+ (error_start_): Replace with...
+ (error_range_): this location array.
+ This allows to replace code relying on the implementation of
+ locations by portable code.
+ * data/yacc.c (yylerrsp): Replace with...
+ (yyerror_range): this.
+ Every time a token is popped, update yyerror_range[0], to have an
+ accurate location for the error token.
+ * data/glr.c (YY_LOCATION_PRINT): New.
+ (yyprocessOneStack): Fix an invocation of YY_SYMBOL_PRINT:
+ deference a pointer.
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): No longer
+ report the location in %printers.
+
+ * src/scan-skel.l: Instead of abort, report error messages to ease
+ understanding skeleton scanning failures.
+
+2004-09-16 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc (Stack::Iterator, Stack::ConstIterator): Rename as...
+ (iterator, const_iterator): these, to be more in the C++ spirit.
+ Also, return reverse iterators so that when displaying the stack
+ we display its bottom first.
+ (Parser::stack_print_, Parser::reduce_print_): Match the messages
+ from yacc.c.
+ We should probably use vector here though.
+
+2004-09-16 Akim Demaille <akim@epita.fr>
+
+ Have more complete shift traces.
+
+ * data/yacc.c, data/lalr1.c, data/glr.c: Use YY_SYMBOL_PRINT
+ to report Shifts instead of ad hoc YYDPRINTF invocations,
+ including for the error token.
+ * data/lalr1.cc (symprint_): Output the location.
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): In C++, don't
+ output the location within the %printer.
+ Activate GLR tests, at least to make sure they compile properly.
+ They still don't pass though.
+ * tests/calc.at: Adjust expect verbose output, since now "Entering
+ state..." is on a different line than the "Shifting" message.
+
+2004-09-08 Akim Demaille <akim@epita.fr>
+
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Move the
+ Bison directive from the Bison file to the invocation of this
+ macro, so that these directives are passed to
+ AT_BISON_OPTION_PUSHDEFS to get correct help macros.
+ Use these helping macros (e.g., AT_LOC, AT_VAL and so forth).
+ Move the AT_SETUP/AT_CLEANUP outside, to report as test title
+ the extra Bison directives instead of the whole series.
+ Change the grammar so that there are recoverable errors, and
+ unrecoverable errors. Now we can have the parser give up before
+ consuming the whole input. As a result we now can observe that
+ the lookahead is freed when needed.
+ Change the parser source to parse argv[1] instead of a hard coded
+ string.
+ Simplify yylex, and give a value and location to EOF.
+ Simplify some invocations of AT_CHECK_PRINTER_AND_DESTRUCTOR that
+ passed directives already coded in the file.
+ Add some tests to check the location of "error".
+ For some tests, the C++ parser is correct, and not yacc.c.
+ For other tests, they provide different, but unsatisfying, values,
+ so keep the C++ value so that at least one parser is "correct"
+ according to the test suite.
+ (Actions after errors): Remove, this is subsumed by the
+ AT_CHECK_PRINTER_AND_DESTRUCTOR series.
+
+2004-09-06 Akim Demaille <akim@epita.fr>
+

+ Call YY_SYMBOL_PRINT.
+ Adjust all callers: integrate the associated YY_SYMBOL_PRINT.
+ * data/lalr1.cc (destruct_): Likewise.
+ In addition, no longer depend on b4_yysymprint_generate and

+ hand".
+
+2004-09-03 Akim Demaille <akim@epita.fr>
+
+ * data/glr.c, data/lalr1.cc, data/yacc.c: When YYABORT was

+
+2004-09-02 Akim Demaille <akim@epita.fr>
+
+ * data/lalr1.cc (b4_yysymprint_generate): New.
+ (symprint_): New member function, defined when YYDEBUG.
+ Use it consistently instead of token/nterm debugging output by

+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Adjust
+ %printer calls to use cdebug_ when using lalr1.cc.
+
+2004-08-30 Florian Krohm <florian@edamail.fishkill.ibm.com>
+

+
+2004-08-13 Paul Eggert <eggert@cs.ucla.edu>
+
+ Adjust to latest gnulib.
+ * bootstrap (gnulib_modules): Add xalloc-die.

+
+2004-08-10 Florian Krohm <florian@edamail.fishkill.ibm.com>

+
+ * src/scan-gram.l (handle_syncline): Use uniqstr_new not xstrdup.

+ (Printers and Destructors): Add non-%union test cases.
+
+2004-06-21 Paul Eggert <eggert@cs.ucla.edu>
+
+ * doc/bison.texinfo: Minor editorial changes, mostly to the new

+
+2004-06-21 Paul Hilfinger <hilfingr@CS.Berkeley.EDU>
+
+ * doc/bison.texinfo (Merging GLR Parses, Compiler Requirements):

+ Rewrite connective text.
+
+2004-06-21 Frank Heckenbach <frank@g-n-u.de>

+ C++ compiler. (trivial change)
+
+2004-05-27 Paul Eggert <eggert@cs.ucla.edu>
+
+ Spent a few hours checking out which prerequisite versions the
+ current sources actually require. I went all the way back to
+ Gettext 0.10.40, Automake 1.4, and Autoconf 2.57 and investigated
+ a seemingly endless set of combinations of versions more recent
+ than that. The bottom line is that the current sources require
+ fairly recent versions of the build tools, and it'll be some work
+ to change this.
+ * configure.ac (AC_PREREQ): Increase from 2.58 to 2.59.
+ (AM_INIT_AUTOMAKE): Increase from 1.7 to 1.8.
+ (AM_GNU_GETTEXT_VERSION): Increase from 0.11.5 to 0.12.
+ Add comments explaining why those particular versions are
+ currently needed.
+
+ * src/parse-gram.y (lloc_default): Rewrite to avoid compiler bug
+ in SGI MIPSpro 7.4.1m. Problem reported by Albert Chin-A-Young in
+ <http://lists.gnu.org/archive/html/bug-bison/2004-05/msg00037.html>.
+
+ * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
+ (it fails with a Autoconf-without-aclocal-m4 diagnostic).
+
+2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
+
+ * configure.ac (AM_GNU_GETTEXT_VERSION): Lower it from 0.14.1 to
+ 0.11.5. Suggested by Bruno Haible.
+ * bootstrap: Remove gettext version checking.
+
+ * doc/bison.texinfo (Decl Summary): Also mention that %union
+ can depend on prerequisite types. Problem reported by Tim
+ Van Holder.
+
+2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
+
+ * README: Mention GNU m4 1.4 bugs and Akim's patched version.
+ * README-alpha: Don't tell people not to package this.

+ Problem reported by Paul Hilfinger. Also, diagnose non-GNU
+ gettext better.
+
+ * doc/bison.texinfo (Decl Summary, Bison Options): Clarify what's
+ put into the -d output file, and mention what to do if YYSTYPE is
+ defined as a macro.
+
+2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
+
+ Undo change made earlier today: it caused autopoint to not bring
+ in ABOUT-NLS. Ouch. Instead, substitute our own diagnostic for
+ autopoint's.
+
+ * bootstrap: Check that gettext version matches what's in
+ configure.ac. Warn users to ignore robots.txt ERROR 404.
+ * bootstrap: Undo today's earlier change (logged below).
+ * configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.
+
+ The gettext version checking is causing more trouble than it's
+ curing; remove it. Problem reported by Paul Hilfinger.
+
+ * bootstrap: Issue a warning that one can expect a message
+ 'AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION'.
+ * configure.ac (AM_GNU_GETTEXT_VERSION): Remove.
+
+2004-05-23 Paul Eggert <eggert@cs.ucla.edu>

+
+ Get files from the gnulib and po repositories, instead of relying

+ * bootstrap: Bootstrap from gnulib and po repositories.
+ Much of this code was stolen from GNU diff and GNU tar's bootstrap.
+ * README-cvs: Document these changes. Remove version numbers from
+ mentions of build tools, since they change so often. Mention Flex.
+
+ * configure.ac (AC_CONFIG_MACRO_DIR): Add, with m4 as arg.
+ (gl_USE_SYSTEM_EXTENSIONS): Add.

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

+2004-02-02 Paul Eggert <eggert@twinsun.com>
+

The problem was that GLR parsers did not conform to the C standard,
because actions like { $1 = $2 + $3; } expanded to expressions
that invoked YYFILL in separate subexpressions, and YYFILL assigned
parser can loop. Provide a test case and a fix for yacc.c. I
