+
+       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.
+

+
+       * 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.
+
+

+
+       * src/LR0.c (augment_automaton): Call `insert_eof_shifting_state'
+       only when appropriate: when insert_start_shifting_state' is not
+       invoked.
+       * tests/regression.at (Rule Line Numbers): Adjust.

+
+       * src/LR0.c (augment_automaton): Now that all states have shifts,
+       merge the two cases addition shifts to the initial state.

+
+       * src/lalr.c (set_state_table): Move to...
+       * src/LR0.c: here.
+       * src/lalr.c (lalr): Don't call it...
+       * src/LR0.c (generate_states): do it.
+       * src/LR0.h (first_state): Remove, only the table is used.
+
+

+
+       * src/LR0.h (first_shift, first_reduction): Remove.
+       * src/lalr.c: Don't use first_shift: find shifts through the
+       states.
+
+       
+2001-12-10  Akim Demaille  <akim@epita.fr>
+
+       * src/LR0.c: Attach shifts to states as soon as they are
+       computed.
+       * src/lalr.c (set_state_table): Instead of assigning shifts to
+       state, just assert that the mapping was properly done.
+
+
