+
+ * src/reader.c (copy_definition): Re-use CPP-outed code which
+ replace precedent remove.
+ * src/bison.simple: Remove #line before %%prologue because
+ %%input-line is wrong at this time.
+
+2001-12-10 Marc Autret <autret_m@epita.fr>
+
+ * src/reader.c (symbols_output): Clean up.
+ * src/output.c (output_gram, output): Clean up.
+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ * src/lalr.c (initialize_lookaheads): New. Extracted from...
+ * src/LR0.c (set_state_table): here.
+ * src/lalr.c (lalr): Call it.
+
+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'
+ only when appropriate: when insert_start_shifting_state' is not
+ invoked.
+ * 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,
+ merge the two cases addition shifts to the initial state.
+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ * 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.
+
+2001-12-10 Akim Demaille <akim@epita.fr>
+
+ * 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.
+
+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.
+ * 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.

Now that states have a complete set of members, the linked list of
the reductions, then the states: free all the states and their
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.

One structure for states is enough, even though theoretically
* src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
