+
+1999-02-22 Jim Lemke <jlemke@cygnus.com>

+
+1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
+
+ Make the simulator compatible with the MPC750. It would be nicer
+ to make this a real multi-sim, but that's more work than we have
+ time for.
+ * emul_generic.c (emul_add_tree_options): Only require strict
+ alignment if it was explicitly requested at configuration time.
+ Don't make it the default for little-endian machines.
+ * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,

+ THRM2, THRM3): Plop in the MPC750 SPR registers.
+ (DABR): This is weird. This was HID5, but the PPC spec says this
+ should be DABR; why did some random processor use it for something
+ else? The HID5 entry dates back to the original checkin of the
+ simulator code in 1995, so remove it.
+ * sim_calls.c (register_names): Delete this; since the user can
+ now change GDB's list of register names dynamically, we can't
+ pretend there's a static mapping here.
+ (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
+ function to get the register name. That ought to be accurate.
+ However, we're changing a compile-time dependency (using the
+ REGISTER_NAMES macro) into a link- and run-time dependency
+ (calling REGISTER_NAME, which happens to be a function call on the
+ PPC).

+
+Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
+
+ * table.c (table_open): For cygwin hosts, we need to use the
+ return value from the read routine as the number of bytes to
+ process. This apparently is due to text-mode vs binary-mode. If
+ the mounts are done text-mode, then the size returnedby fstat()

+ 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
+ reworked idecode.

+
+ * 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.
