1020 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
1022 Make the simulator compatible with the MPC750. It would be nicer

1030 THRM2, THRM3): Plop in the MPC750 SPR registers.
1031 (DABR): This is weird. This was HID5, but the PPC spec says this
1032 should be DABR; why did some random processor use it for something
1033 else? The HID5 entry dates back to the original checkin of the
1034 simulator code in 1995, so remove it.
1035 * sim_calls.c (register_names): Delete this; since the user can
1036 now change GDB's list of register names dynamically, we can't
1037 pretend there's a static mapping here.
1038 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1039 function to get the register name. That ought to be accurate.
1040 However, we're changing a compile-time dependency (using the
1041 REGISTER_NAMES macro) into a link- and run-time dependency
1042 (calling REGISTER_NAME, which happens to be a function call on the

1077 * table.c (table_open): For cygwin hosts, we need to use the
1078 return value from the read routine as the number of bytes to
1079 process. This apparently is due to text-mode vs binary-mode. If
1080 the mounts are done text-mode, then the size returnedby fstat()
1081 may be different than the number of bytes "read" in text mode.

1106 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1108 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1109 but there was no such target, only plain psim. So I changed the
1110 run target to depend on psim.

1521 * psim.c (psim_write_register, psim_read_register): Force the cpu
1522 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1523 next cpu would be zero any way.
1525 * mon.c (mon_print_info): If possible, print the system cycle
1526 performance. This is an indication of the number of instructions
1529 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1531 * The code to allow an event queue to be updated during a signal
1532 was missing. For main.c, a cntrl-c simulation termination wasn't

1536 that the simulation be halted.

1559 * gen-idecode.c (print_run_until_stop_body): Call
1560 event_queue_process_events to clear possibly pending events before
