+
+       * 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.
+
+

+
+       * 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!

+
+       * 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.
+       * src/vmsgetargs.c: Vaguely adjust, but who cares?
+
+       
+2001-12-10  Akim Demaille  <akim@epita.fr>
+
+       * src/muscle_tab.c (muscle_init): NULL is a better default than
+       `"0"'.
+
+       
+2001-12-10  Akim Demaille  <akim@epita.fr>
+
+       * src/reader.c (reader): Calling symbols_output once is enough.
