+ ticks recorded by the event queue.
+
+ * psim.c (psim_write_register, psim_read_register): Force the cpu
+ to zero when it is either of `-1' or `nr_cpus'. In both cases the
+ next cpu would be zero any way.
+
+ * mon.c (mon_print_info): If possible, print the system cycle

+
+ * The code to allow an event queue to be updated during a signal
+ was missing. For main.c, a cntrl-c simulation termination wasn't
+ handled cleanly.
+
+ * The simulation would not correctly restart if an event requested
+ that the simulation be halted.
+
+ * psim.c (psim_options): Add hack to -i option to optionally
+ include a level vis -i2.
+ (psim_usage): Document.
+
+ * main.c (cntrl_c, cntrl_c_simulation): New functions. When a

+ so that it is tolerant of halts.
+ (event_queue_init): Start the event queue out with processing
+ false.
+ (event_queue_tick): Check that processing isn't still being
+ performed.
+
+ * gen-idecode.c (print_run_until_stop_body): Call
+ event_queue_process_events to clear possibly pending events before
+ starting a simulation run. Re-arange main loop so that simulator
+ is correctly restarted when an event halts the simulation.
+
+ * psim.c (psim_halt): Handle an event halting the simulation.
+ * psim.c (psim_init): Adjust initial cpu - == -1 - to match

+ RA. Based on instruction frequency stats, expand additional
+ instructions.
+ * ppc-instructions: Change all `RA == 0' to RA_is_0.
+
+ * ppc-opcode-stupid: Move all but the basic table in -complex into
+ here. Update to new format.
+
+ * Makefile.in (tmp-defines): New target. Force defines.h to always
