[bison.git] / ChangeLog

2001-12-18  Akim Demaille  <akim@epita.fr>

        Version 1.30h.

2001-12-18  Akim Demaille  <akim@epita.fr>

        Some host fail on `assert (!"foo")', which expands to
        ((!"foo") ? (void)0 : __assert("!"foo."", __FILE__, __LINE__))
        Reported by Nelson Beebee.

        * src/output.c, src/vcg.c: Replace `assert (!"it succeeded")' with
        `#define it_succeeded 0' and `assert (it_succeeded)'.

2001-12-17  Paul Eggert  <eggert@twinsun.com>

        * src/bison.simple (YYSTD): New macro.
        (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE, YYFPRINTF, YYSTDERR): Use
        it to simplify macros, and fix some C++ porting problems reported
        by Hans Aberg.

        * src/output.c (output): Define YYDEBUG to 0 if it is not defined
        and if we are not debugging.  POSIX requires this.
        * NEWS, doc/bison.texinfo, doc/bison.1, doc/bison.rnh: Document this.

        * src/output.c (output_gram, output_rule_data): Do not assume that
        the user defines YYDEBUG to a properly parenthesized expression.

2001-12-15  Akim Demaille  <akim@epita.fr>

        * src/nullable.c (set_nullable): Useless rules must be skipped,
        otherwise, since we range over their symbols, we might look at a
        nonterminal which no longer ``exists'', i.e., it is not counted in
        `nvars', hence we overflow our arrays.

2001-12-15  Akim Demaille  <akim@epita.fr>

        * src/reader.c (copy_action): When --yacc, don't append a `;'
        to the user action: let it fail if lacking.
        Suggested by Aharon Robbins and Tom Tromey.

2001-12-13  Akim Demaille  <akim@epita.fr>

        Version 1.30g.

2001-12-13  Akim Demaille  <akim@epita.fr>

        The computation of nullable is broken: it doesn't handle empty
        RHS's properly.

        * tests/torture.at (GNU AWK Grammar): New.
        * tests/sets.at (Nullable): New.
        * src/nullable.c (set_nullable): Instead of blindly looping over
        `ritems', loop over the rules, and then over their rhs's.

        Work around Autotest bugs.

        * src/warshall.c (bitmatrix_print): Don't use `+--+' as table
        frame, because Autotest understand lines starting with a `+' as
        traces from the shell.  Then, they are not processed properly.
        Admittedly an Autotest bug, but we don't have time to wait for
        Autotest to catch up.
        * tests/regression.at (Broken Closure): Adjust to the new table
        frames.
        Move to...
        * tests/sets.at: here.

2001-12-12  Paul Eggert  <eggert@twinsun.com>

        * src/bison.simple (YYSIZE_T, YYSTACK_ALLOC, YYSTACK_FREE):
        Do not infringe on the global user namespace when using C++.
        (YYFPRINTF, YYSTDERR): New macros, needed for the above.
        All uses of `fprintf' and `stderr' changed.

        * src/output.c (output): Do not output "#include <stdio.h>"; that
        is bison.simple's job.  stdio.h should be included only if
        necessary, to avoid infringing on the user name space when
        possible.

2001-12-12  Akim Demaille  <akim@epita.fr>

        * src/complain.h, src/complain.c: Remove error_one_per_line, rely
        on that of lib/error.c.

2001-12-12  Akim Demaille  <akim@epita.fr>

        Some hosts don't like `/' in includes.

        * src/system.h: Include libgettext.h without qualifying the path.
        * src/Makefile.am (INCLUDES): Add $(top_srcdir)/intl, remove
        $(top_srcdir).

2001-12-10  Akim Demaille  <akim@epita.fr>

        Bison dumps core on bash.y.
        Reported by Pascal Bart.

        * src/warshall.c (bitmatrix_print): New.
        (TC): Use it.
        When performing a transitive closure R(i, j) && R(j, k) => R(i, k),
        j must be the outer loop.
        * tests/regression.at (Broken Closure): New.

2001-12-05  Akim Demaille  <akim@epita.fr>

        Version 1.30f.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * tests/atlocal.in (CPPFLAGS): Do not leave a space between -I and
        its argument.
        Reported by Peter Hámorský.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/conflicts.c (err_table): Remove.
        (resolve_sr_conflict): Adjust.
        * src/lalr.h (state_t.reduction_table, state_t.shift_table):
        Rename as...
        (state_t.reductions, state_t.shifts): this.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/reduce.c (reduce_grammar_tables): No longer disable the
        removal of useless rules via CPP but via `if (0)', so that the
        compiler still check the code is valid.
        For instance, it should have noticed `rline' no longer exists: use
        the `line' member of rule_t.
        * src/gram.c (dummy, rline): Remove, unused.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/output.c (pack_vector): Use assert, not berror.
        * src/main.c (berror): Remove, unused.

2001-12-05  Akim Demaille  <akim@epita.fr>

        New experimental feature: if --verbose --trace output all the
        items of a state, not only its kernel.

        * src/print.c (print_core): If `trace_flag', then invoke closure
        before outputting the items of the state (print_core is no longer
        a correct name them).
        (print_results): Invoke new_closure/free_closure if needed.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/LR0.c (new_itemsets): Use nshifts only, not shiftcount.
        * src/closure.c, src/closure.h (itemsetsize): Rename as...
        (nitemset): for consistency with the rest of the project.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/closure.c (print_closure): Improve.
        (closure): Use it for printing input and output.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/closure.c (FIRSTS, FDERIVES): Adjust to reality: they are
        indexed by nonterminals.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/warshall.c (TC, RTC): De-obsfucate (source reduced to 22% of
        what it was!).
        * src/warshall.h: Remove accidental duplication of the content.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/closure.c (set_fderives): De-obfuscate.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/closure.c (print_firsts, print_fderives): De-obfuscate.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/closure.c (set_firsts): De-obfuscate.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/output.c (action_row): De-obfuscate
        using the good o' techniques: arrays not pointers, variable
        locality, BITISSET, RESETBIT etc.

2001-12-05  Akim Demaille  <akim@epita.fr>

        Pessimize the code to simplify it: from now on, all the states
        have a valid SHIFTS, which NSHIFTS is possibly 0.

        * src/LR0.c (shifts_new): Be global and move to..
        * src/state.c, src/state.h: here.
        * src/conflicts, src/lalr.c, src/output.c, src/print.c,
        * src/print_graph: Adjust.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New.
        * src/conflicts.c: Use it.
        Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
        incorrectly ``simplified''.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/conflicts.c (flush_shift, resolve_sr_conflict): De-obfuscate
        using the good o' techniques: arrays not pointers, variable
        locality, BITISSET, RESETBIT etc.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/state.h (SHIFT_SYMBOL): New.
        * src/conflicts.c: Use it to deobfuscate.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/conflicts.c (count_sr_conflicts, count_rr_conflicts)
        (print_reductions): De-obfuscate using the good o' techniques:
        arrays not pointers, variable locality, BITISSET.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/conflicts.c (print_reductions): Arrays, not pointers.
        Use BITISSET.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/conflicts.c (print_reductions): Pessimize, but clarify.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/conflicts.c (print_reductions): Improve variable locality.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/conflicts.c (print_reductions): Pessimize, but clarify.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/conflicts.c (print_reductions): Improve variable locality.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New.
        * src/lalr.c: Use them.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/LR0.c (augment_automaton): Formatting changes.
        Better variable locality.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/lalr.c (matrix_print): New.
        (transpose): Use it.
        Use arrays instead of pointers.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/lalr.c (maxrhs): Move to...
        * src/gram.c, src/gram.h (ritem_longest_rhs): here.
        * src/lalr.c (build_relations): Adjust.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/lalr.c (transpose): Free the memory allocated to the
        argument, as it is replaced by the results by the unique caller.
        (build_relations): Merely invoke transpose: it handles the memory
        deallocation.
        Improve variable locality.
        Avoid variables used as mere abbreviations.
        (compute_lookaheads): Use arrays instead of pointers.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/lalr.c (initialize_F): Improve variable locality.
        Avoid variables used as mere abbreviations.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/derives.c (print_derives): Display the ruleno.
        * src/lalr.c (initialize_F, transpose): Better variable locality
        to improve readability.
        Avoid variables used as mere abbreviations.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/lalr.c (traverse): Use arrays instead of pointers.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/nullable.c (set_nullable): Use a for loop to de-obfuscate
        the handling of squeue.
        `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.

2001-12-05  Akim Demaille  <akim@epita.fr>

        Because useless nonterminals are now kept alive (instead of being
        `destroyed'), we now sometimes examine them, and store information
        related to them.  Hence we need to know their number, and adjust
        memory allocations.

        * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
        static.
        * src/LR0.c (allocate_itemsets): The memory allocated to
        `symbol_count' was used for two different purpose: once to count
        the number of occurrences of each symbol, and later reassigned to
        `shift_symbol', containing the symbol that can be shifted from a
        given state.
        Deobfuscate, i.e., allocate, use and free `symbol_count' here
        only, and...
        (new_itemsets): Allocate `shift_symbol' here.
        (allocate_itemsets): symbol_count includes useless nonterminals.
        Make room for them.
        (free_storage): Use `free', not `XFREE', for pointers that cannot
        be null.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/nullable.c (set_nullable): Deobfuscate the handling of
        ritem.
        `symbol >= 0' is wrong now, use `rule_table[ruleno].useful'.

2001-12-05  Akim Demaille  <akim@epita.fr>

        * src/gram.c, src/gram.h (ritem_print): New.
        * src/gram.c (dummy): Remove, now there is actual code in gram.c.
        (This useless function was defined only to work around VMS linkers
        that can't handle compilation units with variables only).
        * src/reduce.c (dump_grammar): Use it to trace the construction of
        ritem.

2001-12-04  Paul Eggert  <eggert@twinsun.com>

        * src/bison.simple (union yyalloc): Change member names
        to be the same as the stack names.
        (yyparse): yyptr is now union yyalloc *, not char *.
        (YYSTACK_RELOCATE): Likewise.  This avoids a GCC warning,
        and may generate better code on some machines.
        (yystpcpy): Use prototype if __STDC__ is defined, not just
        if __cplusplus is defined.

2001-11-30  Akim Demaille  <akim@epita.fr>

        * configure.in (WARNING_CFLAGS): Add -Werror when possible.
        (CFLAGS): Do not include the WARNING_CFLAGS here, since GNU
        Gettext doesn't compile cleanly, and dies with -Werror.
        * src/Makefile.am, lib/Makefile.am, tests/atlocal.in (CFLAGS):
        Include WARNING_CFLAGS here.
        * lib/xstrdup.c: Include xalloc.h, so that xstrdup be declared
        before being defined.

2001-11-30  Paul Eggert  <eggert@twinsun.com>

        * lib/quotearg.h (quotearg_n, quotearg_n_style):
        First arg is int, not unsigned.
        * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise.
        (SIZE_MAX, UINT_MAX): New macros.
        (quotearg_n_options): Abort if N is negative.
        Avoid overflow check on hosts where size_t is 64 bits and int
        is 32 bits, as overflow is impossible there.
        Fix off-by-one typo that caused unnecessary reallocation.

2001-11-30  Paul Eggert  <eggert@twinsun.com>

        Name space cleanup in generated parser.

        * doc/bison.texinfo (Bison Parser): Discuss system headers
        and their effect on the user name space.

        * src/bison.simple:
        (YYSTACK_ALLOC, YYSTACK_FREE, union yyalloc, YYSTACK_GAP_MAX,
        YYSTACK_BYTES, YYSTACK_RELOCATE): Do not define unless necessary,
        i.e. unless ! defined (yyoverflow) || defined (YYERROR_VERBOSE).

        (YYSIZE_T): New macro.  Use it instead of size_t, to avoid infringing
        on user names when possible.

        (YYSTACK_USE_ALLOCA): Do not define; just use any existing defn.
        Simplify test for whather <alloca.h> exists.

        (<stdlib.h>): Include if we will use malloc, and if standard C or C++.

        (<stdio.h>): Include if YYDEBUG.

        (yymemcpy): Renamed from __yy_memcpy.  Do not define unless
        ! defined (yyoverflow) && ! defined (yymemcpy).

        (yymemcpy, yyparse): Rename local variables as needed so that
        they all begin with 'yy'.

        (yystrlen, yystpcpy): New functions.

        (YY_DECL_NON_LSP_VARIABLES): Renamed from _YY_DECL_VARIABLES.
        All uses changed.

        (yyparse): size_t -> YYSIZE_T.  Use yystrlen and yystpcpy
        instead of relying on string.h functions.  Use YYSTACK_ALLOC
        and YYSTACK_FREE instead of malloc and free.

2001-11-30  Akim Demaille  <akim@epita.fr>

        * src/bison.simple (YYSTACK_FREE): Use `do {;} while (0)' as empty
        if body instead of `;' to pacify GCC's warnings.

2001-11-30  Akim Demaille  <akim@epita.fr>

        Instead of mapping the LHS of unused rules to -1, keep the LHS
        valid, but flag the rules as invalid.

        * src/gram.h (rule_t): `useful' is a new member.
        * src/print.c (print_grammar): Adjust.
        * src/derives.c (set_derives): Likewise.
        * src/reader.c (packgram, reduce_output): Likewise.
        * src/reduce.c (reduce_grammar_tables): Likewise.
        * tests/reduce.at (Underivable Rules, Useless Rules): New.

2001-11-30  Akim Demaille  <akim@epita.fr>

        * src/reduce.c (reduce_output): Formatting changes.
        * src/print.c (print_results, print_grammar): Likewise.
        * tests/regression.at (Rule Line Numbers)
        (Solved SR Conflicts, Unresolved SR Conflicts): Adjust.

2001-11-30  Akim Demaille  <akim@epita.fr>

        * src/reduce.c (nonterminals_reduce): Instead of throwing away
        useless nonterminals, move them at the end of the symbol arrays.
        (reduce_output): Adjust.
        * tests/reduce.at (Useless Nonterminals): Adjust.

2001-11-30  Akim Demaille  <akim@epita.fr>

        * src/reduce.c: Various comment/formatting changes.
        (nonterminals_reduce): New, extracted from...
        (reduce_grammar_tables): here.
        (reduce_grammar): Call nonterminals_reduce.

2001-11-29  Paul Eggert  <eggert@twinsun.com>

        * src/bison.simple (YYSTACK_REALLOC): Remove.
        (YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
        (YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
        New macros.
        (union yyalloc): New type.
        (__yy_memcpy): Last arg is size_t, not unsigned int, to remove
        an arbitrary restriction on hosts where size_t is wider than int.

        (yyparse): Don't dump core if alloca or malloc fails; instead, report
        a parser stack overflow.  Allocate just one block of memory for all
        three stacks, instead of allocating three blocks; this typically is
        faster and reduces fragmentation.

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

2001-11-28  Akim Demaille  <akim@epita.fr>

        * src/LR0.c (shifts_new): New.
        (save_shifts, insert_start_shift, augment_automaton): Use it.

2001-11-28  Akim Demaille  <akim@epita.fr>

        * src/closure.c (closure): `b' and `ruleno' denote the same value:
        keep ruleno only.

2001-11-28  Akim Demaille  <akim@epita.fr>

        * src/closure.c (closure): Instead of looping over word in array
        then bits in words, loop over bits in array.

2001-11-28  Akim Demaille  <akim@epita.fr>

        * src/closure.c (closure): No longer optimize the special case
        where all the bits of `ruleset[r]' are set to 0, to make the code
        clearer.

2001-11-28  Akim Demaille  <akim@epita.fr>

        * src/closure.c (closure): `r' and `c' are new variables, used to
        de-obfuscate accesses to RULESET and CORE.

2001-11-28  Akim Demaille  <akim@epita.fr>

        * src/reduce.c (reduce_print): Use ngettext.
        (dump_grammar): Improve the trace accuracy.

2001-11-28  Akim Demaille  <akim@epita.fr>

        * src/reduce.c (dump_grammar): Don't translate trace messages.

2001-11-28  Akim Demaille  <akim@epita.fr>

        * tests/reduce.at (Useless Terminals, Useless Nonterminals): New.
        * src/reduce.c (reduce_grammar_tables): Do not free useless tags,
        as all tags are free'ed afterwards.
        From Enrico Scholz.

2001-11-23  Akim Demaille  <akim@epita.fr>

        Attaching lineno to buckets is stupid, since only one copy of each

        * src/print_graph.c: Don't.

        * tests/calc.at, tests/output.at, tests/regression.at,
        * tests/testsuite.at, tests/torture.at: Rely on Autotest 2.52g:

        * tests/calc.at (AT_CHECK_CALC): Don't try to check the compiler's

        * src/bison.simple (yyparse): Let yyls1, yyss1 and yyvs1 be

2001-11-14  Akim Demaille  <akim@epita.fr>

        * src/print.c: Include reduce.h.
        Reported by Hans Aberg.

2001-11-14  Akim Demaille  <akim@epita.fr>

        * src/lex.c, src/lex.h (token_buffer, unlexed_token_buffer):
        Revert a previous patch:  these are really const.

        braces to pacify GCC's warnings for `if () if () {} else {}'.
        * src/lex.c (parse_percent_token): Replace equal_offset with
        arg_offset.
        arg is const.

        Also free V1.
        (reduce_grammar): No longer call reduce_output, since...
        * src/print.c (print_results): do it.
        * src/main.c (main): Call reduce_free;

2001-11-12  Akim Demaille  <akim@epita.fr>

2001-11-04  Akim Demaille  <akim@epita.fr>

        * src/getargs.c (longopts): Support `--output'.  getopt is now
        able to understand that `--out' is OK: the two racing long options
        are aliases.
        (usage): Adjust.
        * src/lex.h (tok_setopt): Remove, replaced with...
        (tok_intopt, tok_stropt): these new guys.

        * doc/bison.texinfo (Decl Summary): Split the list into
        `directives for grammars' and `directives for bison'.
        Sort'em.
        Add description of `%name-prefix', `file-prefix', and `output'.
        Promote `-' over `_' in directive names.

2000-12-19  Akim Demaille  <akim@epita.fr>

        * src/files.c (open_files): Yipee!  We no longer need all the code
        looking for `/tmp' since we have no tmp file.

2000-12-19  Akim Demaille  <akim@epita.fr>

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

        (obstack_grow, obstack_grow0): Don't cast WHERE at all: it
        prevents type checking.
        (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
        cast the value to (void *): assigning a `foo *' to a `void *'
        variable is valid.
        (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
        * src/reader.c (parse_union_decl): Typo: use obstack_1grow to

        (obstack_grow0, obstack_ptr_grow, obstack_ptr_grow_fast): Qualify
        `const' their input argument (`data' or `address').
        Adjust the corresponding macros to include `const' in casts.

2000-11-03  Akim Demaille  <akim@epita.fr>

        (output_files): this.
        Use `obstack_save'.
        * src/main.c (main): Don't use `atexit' to register `done', since
        it no longer has to remove tmp files, just call `output_files'
        when there are no errors.

2000-11-02  Akim Demaille  <akim@epita.fr>

        * src/files.c [VMS]: No longer include `ssdef.h', no longer define

        * src/reader.c (copy_comment2): Expect the input stream to be on
        the `/' which is suspected to open a comment, instead of being
        called after `//' or `/*' was read.

        * bison.s1 (yyparse): Assign the default value
        unconditionally, to avoid a GCC warning and make the parser a
        tad smaller.

        * src/getargs.c (getargs): Don't dump `--help' on unrecognized

2000-10-02  Akim Demaille  <akim@epita.fr>

        * src/derives.c, src/print.c, src/reduce.c: To ease the
        translation, move some `\n' out of the translated strings.

2000-10-02  Akim Demaille  <akim@epita.fr>

        The location tracking mechanism is precious for parse error
        messages.  Nevertheless, it is enabled only when `@n' is used in
        the grammar, which is a different issue (you can use it in error
        message, but not in the grammar per se).  Therefore, there should
        be another means to enable it.

        * src/getargs.c (getargs): Support `--locations'.
        (usage): Report it.
        * src/getargs.h (locationsflag): Export it.
        * src/lex.c (percent_table): Support `%locations'.
        * src/reader.c (yylsp_needed): Remove this variable, now replaced
        with `locationsflag'.
        * doc/bison.texinfo: Document `--locations' and `%locations'.
        Sort the options.
        * tests/calc.m4: Test it.

        For regularity of the names, replace each
        (nolineflag, toknumflag, rawtokenumflag, noparserflag): with...
        (no_lineflag, token_tableflag, rawflag, no_parserflag): this.
        In addition replace each `flag' with `_flag'.

2000-10-02  Akim Demaille  <akim@epita.fr>

        Also test parse error messages, including with YYERROR_VERBOSE.

        * tests/calc.m4 (calc.y): Add support for `exp = exp' (non
        associative).
        Use it to check the computations.
        Use it to check `nonassoc' is honored.
        (AT_DATA_CALC_Y): Equip `calc.y' with YYERROR_VERBOSE when passed
        `--yyerror-verbose'.
        (_AT_CHECK_CALC): Adjust to this option.
        (_AT_CHECK_CALC_ERROR): New macro to check parse error messages.

2000-10-02  Akim Demaille  <akim@epita.fr>

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

        #if YYDEBUG
        if (yydebug)
        {
        ...
        }
        #endif

        into

        if (yydebug)
        {
        ...
        }

        unfortunately this leads to a CPP conflict when
        `--name-prefix=foo' is used since it produces `#define yydebug
        foodebug'.

        * src/bison.s1 [!YYDEBUG]: Do not define yydebug.
        (YYDPRINTF): New macro.
        Spread its use.
        * tests/calc.m4 (AT_CHECK_CALC): Do require a title, build it from
        the bison options.
        Also test `--verbose', `--defines' and `--name-prefix'.

2000-10-02  Akim Demaille  <akim@epita.fr>

        Improve the readability of the produced parsers.

        * src/bison.s1: Formatting changes.
        Improve the comment related to the `$' mark.
        (yydefault): Don't fall through to `yyresume': `goto' there.
        * src/output.c (output_parser): When the `$' is met, skip the end
        of its line.
        New variable, `number_of_dollar_signs', to check there's exactly
        one `$' in the parser skeleton.

2000-10-02  Akim Demaille  <akim@epita.fr>

        * lib/xstrdup.c: New file, from the fileutils.
        * src/reader.c (parse_token_decl, get_type_name, parse_type_decl)
        (parse_assoc_decl, parse_thong_decl, get_type): Use `xstrdup'
        instead of strlen + xmalloc + strcpy.
        * src/symtab.c (copys): Remove, use xstrdup instead.

2000-10-02  Akim Demaille  <akim@epita.fr>

        * src/gram.h (associativity): New enum type which replaces the
        former CPP macros `RIGHT_ASSOC', `LEFT_ASSOC' and `NON_ASSOC' with
        `right_assoc', `left_assoc' and `non_assoc'.
        Adjust all dependencies.
        * src/reader.c: Formatting changes.
        (LTYPESTR): Don't define it, use it as a literal in
        `reader_output_yylsp'.
        * src/symtab.h (symbol_class): New enum type which replaces the
        former CPP macros `SUNKNOWN', `STOKEN and `SNTERM' with
        `sunknown', `stoken and `snterm'.

2000-10-02  Akim Demaille  <akim@epita.fr>

        * src/getargs.c (fixed_outfiles): Rename as...
        (yaccflag): for consistency and accuracy.
        Adjust dependencies.

2000-10-02  Akim Demaille  <akim@epita.fr>

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

        * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove.
        * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New
        files.

2000-10-02  Akim Demaille  <akim@epita.fr>

        * src/state.h (nstates, final_state, first_state, first_shift)
        (first_reduction): Move their exportation from here...

        Adjust dependencies.
        * src/getargs.c (statisticsflag): New variable.
        Add support for `--statistics'.
        Adjust dependencies.

        Remove a lot of now useless `extern' statements in most files.

        * src/conflicts.c (conflict_report): New function.

        Adjust dependencies.

        Propagate its inclusion.

        (bool, TRUE, FALSE): Move their definition to...
        * src/system.h: here.

        * src/lalr.c: Formatting changes, topological sorting etc.

2000-10-02  Akim Demaille  <akim@epita.fr>

        * src/output.c (token_actions): Introduce a temporary array,
        YYDEFACT, that makes it possible for this function to use
        output_short_table.

2000-10-02  Akim Demaille  <akim@epita.fr>

        `user_toknums' is output as a `short[]' in `output.c', while it is
        defined as a `int[]' in `reader.c'.  For consistency with the
        other output tables, `user_toknums' is now defined as a table of
        shorts.

        * src/reader.c (user_toknums): Be a short table instead of an int
        table.
        Adjust dependencies.

        (output_base, output_table, output_check):  Use it.

        There is now a pseudo variable @$ (readble and writable), location
        of the lhs of the rule (by default ranging from the location of
