+
+       Remove uses of 'short int' and 'unsigned short int'.  This raises
+       some arbitrary limits.  It uses more memory but nowadays that's
+       not much of an issue.
+
+       This change does not affect the generated parsers; that's a different
+       task, as some users will want to conserve memory there.
+
+       Ideally we should use size_t to represent all object counts, and
+       something like ptrdiff_t to represent signed differences of object
+       counts; but that will require more code-cleanup than I have the
+       time to do right now.
+
+       * src/LR0.c (allocate_itemsets, new_itemsets, save_reductions):
+       Use size_t, not int or short int, to count objects.
+       * src/closure.c (nritemset, closure): Likewise.
+       * src/closure.h (nritemset, closure): Likewise.
+       * src/nullable.c (nullable_compute): Likewise.
+       * src/print.c (print_core): Likewise.

+       * src/tables.c (default_goto, goto_actions): Likewise.
+
+       * src/gram.h (rule_number, rule): Use int, not short int.
+       * src/output.c (prepare_rules): Likewise.
+       * src/state.h (state_number, STATE_NUMBER_MAXIMUM, transitions,
+       errs, reductions): Likewise.
+       * src/symtab.h (symbol_number, SYMBOL_NUMBER_MAXIMUM, struct symbol):
+       Likewise.
+       * src/tables.c (vector_number, tally, action_number,
+       ACTION_NUMBER_MINIMUM): Likewise.
+       * src/output.c (muscle_insert_short_int_table): Remove.

+       "foo$$bar = foo$1bar;".  Problem reported by twlevo at xs4all.
+       * data/lalr1.cc (b4_lhs_value, b4_rhs_value, b4_lhs_location,
+       b4_rhs_location): Likewise.

+       renamed, as is the case with other skeletons.
+
+2004-12-16  Akim Demaille  <akim@epita.fr>
+

+       * src/symtab.c (symbol_new): Report an error if the input grammar

+
+2004-12-15  Akim Demaille  <akim@epita.fr>
+
+       Remove b4_root related material: failure experiment

+       definitions and uses.
+
+2004-12-14  Paul Eggert  <eggert@cs.ucla.edu>
+
+       * data/glr.c (struct yyGLRStack): yyerror_range now has 3 items,
+       not 2, since it's not portable to subtract 1 from the start of an
+       array.  The new item 0 is never set or used.  All uses changed.
+
+       (yyrecoverSyntaxError): Use YYLLOC_DEFAULT instead of assuming

+
+       * 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.
+
+2004-12-10  Paul Eggert  <eggert@cs.ucla.edu>

+
+       * src/scan-skel.l: Include "complain.h", for "fatal".
+
+       * src/relation.h (relation_print, relation_digraph):
+       Relation sizes are of type relation_node, not size_t (this is
+       merely a doc fix, since the two types are equivalent).
+       (relation_transpose): Relation sizes are of type relation_node,
+       not int.
+       * src/relation.c: Likewise.
+       (top, infinity): Now of type relation_node, not int.
+       (traverse, relation_transpose): Use relation_node, not int.

+
+       * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): New arg
+       specifying whether the test should be skipped.  Use it tp

+       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,
+       to allocate kernel_base, kernel_items, kernel_size, since
+       they needn't be initialized to 0.
+       (allocate_storgae): Likewise, for shiftset, redset, shift_symbol.
+       * src/closure.c (new_closure): Likewise, for itemset.

+
+       * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base
+       for initial core.  Just have a separate core, so we needn't worry
+       about whether kernel_size and kernel_base are initialized.

+       Likewise.
+
+       * src/closure.c (new_closure): Arg is of type unsigned int, not int.
+       This is because all callers pass unsigned int.
+       * src/closure.h (new_closure): Likewise.
+
+       * src/lalr.c (initialize_F): Initialize reads[i] in all cases.
+       (build_relations): Initialize includes[i] in all cases.
+       * src/reader.c (packgram): Always initialize rules[ruleno].prec

+
+       * src/output.c (prepare_actions): Pass 0 instead of conflict_list[0];
+       conflict_list[0] was always 0, but now it isn't initialized.

+       * src/lalr.c (set_goto_map): Don't allow ngotos to equal
+       GOTO_NUMBER_MAXIMUM, since we occasionally compute
+       ngotos + 1 without checking for overflow.
+       (build_relations): Use END_NODE, not -1, to denote end of edges.
+       * src/lalr.c (set_goto_map, map_goto, initialize_F, add_loopback_edge,
+       build_relations): Use goto_number, not int, for goto numbers.
+       * src/tables.c (save_column, default_goto): Likewise.
+

+

+       of #defining from yystype.
+       Don't typedef yystype, C++ does not need it.
+       This lets it possible to forward declare it as union.

 2004-11-23  Paul Eggert  <eggert@cs.ucla.edu>
 
        * bootstrap (gnulib_modules): Add extensions.
 
        * 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

        * configure.ac (AC_PREREQ): Bump to 2.58, since 2.57 doesn't work
        (it fails with a Autoconf-without-aclocal-m4 diagnostic).
        Ensure that the C++ compiler used for testing actually works on a
        simple test program; if not, skip the C++-related tests.  Problem
        reported by Vin Shelton in:

        * NEWS: Document hexadecimal tokens, no NUL bytes, %destructor
        in lalr1.cc.
        * tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Ignore stdout from
        compilers.  This fixes a problem with Intel's C++ compiler being

 2004-02-09  Alexandre Duret-Lutz  <adl@gnu.org>
 
 
        Have lalr1.cc catch with Paul Eggert's patch to fix the infinite
        error recovery loops.  This patch is based on
-       <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
+       <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00000.html>.
        Also, augment the similarity between lalr1.cc and yacc.c.
        Note: the locations of error recovery rules are not correct yet.
 
 
        * data/glr.c (yyglrReduce): Don't use C89 string concatenation,
        for portability to K&R C (after ansi2knr, presumably).  See
-       <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
+       <http://lists.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>
        by Frank Heckenbach, though I have omitted the structure-initialization
        part of his glr-knr.diff patch since I recall that the Portable
        C Compiler didn't require that change.
 
        Let the user specify how to allocate and free memory.
        Derived from a suggestion by Frank Heckenbach in
-       <http://mail.gnu.org/archive/html/bison-patches/2003-06/msg00041.html>.

        * data/glr.c (YYFREE, YYMALLOC, YYREALLOC): New macros.
        All uses of free, malloc, realloc changed to use these macros,
        and unnecessary casts removed.
 
        * data/lalr1.cc (operator<<(std::ostream&, const Position&)):

        Fix a GLR parser bug I reported in February; see
-       <http://mail.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
+       <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00008.html>.
        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
        don't have a fix for lalr1.cc or for glr.c, unfortunately.
        The original bug report is in:

+       <http://lists.gnu.org/archive/html/bison-patches/2003-02/msg00044.html>
 
        * data/yacc.c (YYERROR): Now just 'goto yyerrorlab', since the
        macro's size was becoming unwieldy.
        * lib/bitset.h (__INT_TO_PTR): Define to a value that presumes
        C89.  This avoids a diagnostic on compilers that define __STDC__
        to 0, fixing a problem with Tru64 cc reported by Martin Mokrejs in
