+2002-04-07  Akim Demaille  <akim@epita.fr>
+
+	As a result of the previous patch, it is no longer needed
+	to reorder ritem itself.
+
+	* src/reduce.c (reduce_grammar_tables): Don't sort RITEM.
+
+2002-04-07  Akim Demaille  <akim@epita.fr>
+
+	Be sure never to walk through RITEMS, but use only data related to
+	the rules themselves. RITEMS should be banished.
+
+	* src/output.c (output_token_translations): Rename as...
+	(prepare_tokens): this.
+	In addition to `translate', prepare the muscles `tname' and
+	`toknum', which were handled by...
+	(output_rule_data): this.
+	Remove, and move the remainder of its outputs into...
+	(prepare_rules): this new routines, which also merges content from
+	(output_gram): this.
+	(prepare_rules): Be sure never to walk through RITEMS.
+	(output_stos): Rename as...
+	(prepare_stos): this.
+	(output): Always invoke prepare_states, after all, just don't use it
+	in the output if you don't need it.
+
+2002-04-07  Akim Demaille  <akim@epita.fr>
+
+	* src/LR0.c (new_state): Display `nstates' as the name of the
+	newly created state.
+	Adjust to initialize first_state and last_state if needed.
+	Be sure to distinguish the initial from the final state.
+	(new_states): Create the itemset of the initial state, and use
+	new_state.
+	* src/closure.c (closure): Now that the initial state has its
+	items properly set, there is no need for a special case when
+	creating `ruleset'.
+
+	As a result, now the rule 0, reducing to $axiom, is visible in the
+	outputs.  Adjust the test suite.
+
+	* tests/conflicts.at (Solved SR Conflicts)
+	(Unresolved SR Conflicts): Adjust.
+	* tests/regression.at (Web2c Report, Rule Line Numbers): Idem.
+	* tests/conflicts.at (S/R in initial): New.
+
+2002-04-07  Akim Demaille  <akim@epita.fr>
+
+	* src/LR0.c (allocate_itemsets): Don't loop over ritem: loop over
+	the RHS of the rules.
+	* src/output.c (output_gram): Likewise.
+
+2002-04-07  Akim Demaille  <akim@epita.fr>
+
+	* src/gram.h (rule_t): `lhs' is now a pointer to the symbol's
+	bucket.
+	Adjust all dependencies.
+	* src/reduce.c (nonterminals_reduce): Don't forget to renumber the
+	`number' of the buckets too.
+	* src/gram.h: Include `symtab.h'.
+	(associativity): Move to...
+	* src/symtab.h: here.
+	No longer include `gram.h'.
+
+	
+2002-04-07  Akim Demaille  <akim@epita.fr>
+
+	* src/gram.h, src/gram.c (rules_rhs_length): New.
+	(ritem_longest_rhs): Use it.
+	* src/gram.h (rule_t): `number' is a new member.
+	* src/reader.c (packgram): Set it.
+	* src/reduce.c (reduce_grammar_tables): Move the useless rules at
+	the end of `rules', and count them out of `nrules'.
+	(reduce_output, dump_grammar): Adjust.
+	* src/print.c (print_grammar): It is no longer needed to check for
+	the usefulness of a rule, as useless rules are beyond `nrules + 1'.
+	* tests/reduce.at (Reduced Automaton): New test.
+

 	* src/reduce.c (inaccessable_symbols): Fix a buglet: because of a
