+2001-12-15 Akim Demaille <akim@epita.fr>
+
+ Make `make distcheck' work.
+
+ * lib/Makefile.am (INCLUDES): Add top_srcdir/intl, since hash uses
+ system.h which uses libgettext.h.
+
+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

+ `nvars', hence we overflow our arrays.
+
+2001-12-15 Akim Demaille <akim@epita.fr>
+
+ The header can also be produced directly, without any obstack!

+
+ * src/files.c, src/files.h (defines_obstack): Remove.
+ (compute_header_macro): Global.

+ (parser_file_name): New.
+ * src/files.c (compute_output_file_names): Compute it.

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

+
+2001-12-13 Akim Demaille <akim@epita.fr>
+
+ * src/print.c (print_actions): Output the handling of `$' as the
+ traces do: shifting the token EOF. Before EOF was treated as a
+ nonterminal.
+ * tests/regression.at: Adjust some tests.
+ * src/print_graph.c (print_core): Complete the set of items via
+ closure. The next-to-final and final states are still unsatisfying,
+ but that's to be addressed elsewhere.
+ No longer output the rule numbers, but do output the state number.
+ A single loop for the shifts + gotos is enough, but picked a

+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ * src/state.h (shifts): Remove the `number' member: shifts are
+ attached to state, hence no longer need to be labelled with a
+ state number.
+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ Now that states have a complete set of members, the linked list of
+ shifts is useless: just fill directly the state's shifts member.
+
+ * src/state.h (shifts): Remove the `next' member.
+ * src/LR0.c (first_state, last_state): Remove.
+ Adjust the callers.
+ (augment_automaton): Don't look for the shifts that must be added
+ a shift on EOF: it is those of the state we looked for! But now,
+ since shifts are attached, it is no longer needed to looking
+ merely by its id: its number.
+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ * src/LR0.c (augment_automaton): Better variable locality.
+ Remove an impossible branch: if there is a state corresponding to
+ the start symbol being shifted, then there is shift for the start
+ symbol from the initial state.
+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'

+ * tests/regression.at (Rule Line Numbers): Adjust.
+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ * src/LR0.c (augment_automaton): Now that all states have shifts,

+
+ * src/lalr.c (set_state_table): Move to...

+
+ * src/LR0.h (first_shift, first_reduction): Remove.

+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ * src/LR0.c: Attach shifts to states as soon as they are
+ computed.

+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ * src/LR0.c (insert_start_shift): Rename as...
+ (insert_start_shifting_state): this.
+ (insert_eof_shifting_state, insert_accepting_state): New.
+ (augment_automaton): Adjust.
+ Better locality of the variables.
+ When looking if the start_symbol is shifted from the initial
+ state, using `while (... symbol != start_symbol ...)' sounds
+ better than `while (... symbol < start_symbol ...)': If fail
+ to see how the order between symbols could be relevant!
+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ * src/getargs.h: Don't declare `spec_name_prefix' and
+ `spec_file_prefix', declared by src/files.h.
+ * src/files.c, src/files.h: Default for spec_name_prefix is "yy".
+ * src/muscle_tab.c (muscle_init): Default prefix to NULL.
+ * src/output.c (prepare): Adjust.
+ * src/reader.c (symbols_output): Likewise.

+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ * src/muscle_tab.c (muscle_init): NULL is a better default than

+
+ * src/reader.c (reader): Calling symbols_output once is enough.
+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ Now that states have a complete set of members, the linked list of
+ reductions is useless: just fill directly the state's reductions

+
+ * src/state.h (struct reductions): Remove member `number' and

+ * src/LR0.c (first_reduction, last_reduction): Remove.
+ (save_reductions): Don't link the new reductions, store them in
+ this_state.
+ * src/lalr.c (set_state_table): No need to attach reductions to

+ * src/output.c (output_actions): No longer free the shifts, then

+ members.
+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ * src/options.c (OPTN, DRTV, BOTH): New.
+ (option_table): Use them.
+
+ * src/muscle_tab.c: Don't include xalloc.h and string.h: that's
+ the job of system.h.
+ * src/options.c: Don't include stdio.h and xalloc.h for the same
+ reasons.
+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ * src/output.c (output, prepare): Make sure the values of the

+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ Clean up GCC warnings.
+
+ * src/reader.c (copy_action): `buf' is not used.

+ Adjust casts to preserve the const.
+
+2001-12-10 Akim Demaille <akim@epita.fr>
+

+ * tests/Makefile.am: Adjust.
+
+2001-12-10 Akim Demaille <akim@epita.fr>
+

+ (state_table): Be state_t **, not state_t *.
+ * src/state.h (core, CORE_ALLOC): Rename as...
+ (state_t, STATE_ALLOC): this.
+ Add the LALR(1) members: shifts, reductions, errs.
+ * src/LR0.c (state_table): Rename as...

+ * src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c

+
+ * src/warshall.c (bitmatrix_print): New.

+2001-12-05 Akim Demaille <akim@epita.fr>
+
+ * src/reduce.c (reduce_grammar_tables): No longer disable the

+
+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.

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

+
+2001-12-05 Akim Demaille <akim@epita.fr>
+
+ Pessimize the code to simplify it: from now on, all the states

+
+ * src/lalr.c (transpose): Free the memory allocated to the

+
+ Because useless nonterminals are now kept alive (instead of being

+ Deobfuscate, i.e., allocate, use and free `symbol_count' here

+
+ * src/bison.simple (union yyalloc): Change member names

+ * 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.
+
+2001-11-27 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.
+
+2001-11-29 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.

+
+ * src/bison.simple (YYSTYPE, YYLTYPE): Move their definitions
+ before their first uses.
+ (YYBISON, YYPURE): Move to the top of the output.

+ * tests/reduce.at (Useless Nonterminals): Fix.

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

Instead of mapping the LHS of unused rules to -1, keep the LHS
* src/files.h (graph_obstack): New extern declaration.
* src/Makefile.am: Add new source files.
