1006 1999-04-02 Keith Seitz <keiths@cygnus.com>

1024 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
1026 Make the simulator compatible with the MPC750. It would be nicer
1027 to make this a real multi-sim, but that's more work than we have
1029 * emul_generic.c (emul_add_tree_options): Only require strict
1030 alignment if it was explicitly requested at configuration time.
1031 Don't make it the default for little-endian machines.

1034 THRM2, THRM3): Plop in the MPC750 SPR registers.
1035 (DABR): This is weird. This was HID5, but the PPC spec says this
1036 should be DABR; why did some random processor use it for something
1037 else? The HID5 entry dates back to the original checkin of the
1038 simulator code in 1995, so remove it.
1039 * sim_calls.c (register_names): Delete this; since the user can
1040 now change GDB's list of register names dynamically, we can't
1041 pretend there's a static mapping here.
1042 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1043 function to get the register name. That ought to be accurate.
1044 However, we're changing a compile-time dependency (using the
1045 REGISTER_NAMES macro) into a link- and run-time dependency
1046 (calling REGISTER_NAME, which happens to be a function call on the

1081 * table.c (table_open): For cygwin hosts, we need to use the
1082 return value from the read routine as the number of bytes to
1083 process. This apparently is due to text-mode vs binary-mode. If
1084 the mounts are done text-mode, then the size returnedby fstat()
1085 may be different than the number of bytes "read" in text mode.

1110 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1112 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1113 but there was no such target, only plain psim. So I changed the

1526 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1527 next cpu would be zero any way.
1529 * mon.c (mon_print_info): If possible, print the system cycle
1530 performance. This is an indication of the number of instructions
1533 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1535 * The code to allow an event queue to be updated during a signal

1664 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1665 scratch variable is defined when a cache entry is beinf

1668 * gen-icache.c: Update.
