+1999-04-02 Keith Seitz <keiths@cygnus.com>
+
+ * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak

+ (poll_quit_count): New global.
+ (sim_io_poll_quit): Only call the poll_quit callback

+
+1999-02-22 Jim Lemke <jlemke@cygnus.com>
+
+ * dc-complex: Force expansion on all bits of field BO.

+ * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.
+ * interrupts.h: Added "mpc860c0_instruction_program_interrupt".
+ * interrupts.c (program_interrupt): Added handling for above interrupt.
+
+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,
+ MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
+ 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).
+
+1999-01-22 Jim Lemke <jlemke@cygnus.com>

+
+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()

+
+ * psim.c (psim_options): Add hack to -i option to optionally
+ include a level vis -i2.
+ (psim_usage): Document.

+
+ * FIXME: The trace code is too scattered - hw_trace.c, psim.c,

+
+ * The code that put values in and extracted values from the cache

+ computed from cache entries. #defines could only be used when a
+ cache was present, remove the restriction.
+
+ * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
+ scratch variable is defined when a cache entry is beinf

+
+ * ld-cache.h, ld-cache.c: Change field names so that their meaning
