+
+ 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.

+
+ * 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.
