+
+	* gen-icache.c: Generalize code handling XXX_is_NNN so that it

+
+	* psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now

+ 	max iterations exceeded.
+
+	* gen-idecode.c: Re-work the table lookup code so that it assumes
+ 	that the entry is a leaf by default.  Simplify the boolean table
+ 	entry code so that it involves a mask + test instead of shift +
+ 	shift + mask + test.
+

+	* When performance monitoring is disabled, it is still possible to
+ 	determine the simulation speed by looking at the number of elapsed
+ 	ticks recorded by the event queue.
+	
+	* psim.c (psim_write_register, psim_read_register): Force the cpu

+ 	next cpu would be zero any way.

+
+	* 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
+ 	cntrl-c occures schedule an event to halt the simulation.
+	(main): Catch CNTRL-C signals with the function cntrl_c.
+
+	* events.c (event_queue_process): Mask interrupts while
+ 	manipulating the async event queue.
+	(event_queue_init): Ditto.
+	(event_queue_schedule_after_signal): Ditto.
+
+	* events.c (event_queue_process): Mark the event queue as being in
+ 	the processing state when processing has started.  Adjust code
+	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

+	* ppc-opcode-complex: Correct typo - was expanding ORA instead of
+ 	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
+ 	be built.  Hence get ppc-opcode-goto to build.
