1051 Make the simulator compatible with the MPC750. It would be nicer
1052 to make this a real multi-sim, but that's more work than we have
1053 time for.
1054 * emul_generic.c (emul_add_tree_options): Only require strict
1055 alignment if it was explicitly requested at configuration time.
1056 Don't make it the default for little-endian machines.
1057 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
1058 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1059 THRM2, THRM3): Plop in the MPC750 SPR registers.
1060 (DABR): This is weird. This was HID5, but the PPC spec says this
1061 should be DABR; why did some random processor use it for something
1062 else? The HID5 entry dates back to the original checkin of the
1063 simulator code in 1995, so remove it.
1064 * sim_calls.c (register_names): Delete this; since the user can
1065 now change GDB's list of register names dynamically, we can't
1066 pretend there's a static mapping here.
1067 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1068 function to get the register name. That ought to be accurate.
1069 However, we're changing a compile-time dependency (using the
1070 REGISTER_NAMES macro) into a link- and run-time dependency
1071 (calling REGISTER_NAME, which happens to be a function call on the
1072 PPC).

1104Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1105
1106 * table.c (table_open): For cygwin hosts, we need to use the
1107 return value from the read routine as the number of bytes to
1108 process. This apparently is due to text-mode vs binary-mode. If
1109 the mounts are done text-mode, then the size returnedby fstat()
1110 may be different than the number of bytes "read" in text mode.

c906108c
SS
3072
3073 * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
