1070 Make the simulator compatible with the MPC750. It would be nicer
1071 to make this a real multi-sim, but that's more work than we have
1072 time for.
1073 * emul_generic.c (emul_add_tree_options): Only require strict
1074 alignment if it was explicitly requested at configuration time.
1075 Don't make it the default for little-endian machines.
1076 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
1077 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1078 THRM2, THRM3): Plop in the MPC750 SPR registers.
1079 (DABR): This is weird. This was HID5, but the PPC spec says this
1080 should be DABR; why did some random processor use it for something
1081 else? The HID5 entry dates back to the original checkin of the
1082 simulator code in 1995, so remove it.
1083 * sim_calls.c (register_names): Delete this; since the user can
1084 now change GDB's list of register names dynamically, we can't
1085 pretend there's a static mapping here.
1086 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1087 function to get the register name. That ought to be accurate.
1088 However, we're changing a compile-time dependency (using the
1089 REGISTER_NAMES macro) into a link- and run-time dependency
1090 (calling REGISTER_NAME, which happens to be a function call on the
1091 PPC).

1123Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1124
1125 * table.c (table_open): For cygwin hosts, we need to use the
1126 return value from the read routine as the number of bytes to
1127 process. This apparently is due to text-mode vs binary-mode. If
1128 the mounts are done text-mode, then the size returnedby fstat()
1129 may be different than the number of bytes "read" in text mode.

1157 but there was no such target, only plain psim. So I changed the
1158 run target to depend on psim.

1635
1636 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1637 to be initialized independant of the rest of the simulation
1638 initalization. Otherwize a trace option explictly set from gdb
1639 could be overridden by hw_trace.
1640
1641 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1642

3045
3046 * gen-idecode.c (print_idecode_switch_illegal): Include a break

c906108c
SS		 3091
3092 * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and

72f4393d 3138 instead of just the code to handle a single instruction issue.
c906108c
SS		 3139 * : Have the generated idecode.c include inline.c (instead of psim.c).
3140
3141 * std-config.h: Change psim.c so that it isn't inlined (as this is

SS		 3143
3144 * psim.c (run_until_stop): Delete the old run_until_stop function
72f4393d
L		 3145 instead calling the idecode_run and idecode_run_until_stop
3146 functions that gen-idecode.c is now creating.

3181 * gen-idecode.c (print_jump_until_stop_body): New function and
72f4393d
L		 3182 idecode generation option. Instead of generating and calling
