648 Make the simulator compatible with the MPC750. It would be nicer
649 to make this a real multi-sim, but that's more work than we have
650 time for.
651 * emul_generic.c (emul_add_tree_options): Only require strict
652 alignment if it was explicitly requested at configuration time.
653 Don't make it the default for little-endian machines.
654 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
655 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
656 THRM2, THRM3): Plop in the MPC750 SPR registers.
657 (DABR): This is weird. This was HID5, but the PPC spec says this
658 should be DABR; why did some random processor use it for something
659 else? The HID5 entry dates back to the original checkin of the
660 simulator code in 1995, so remove it.
661 * sim_calls.c (register_names): Delete this; since the user can
662 now change GDB's list of register names dynamically, we can't
663 pretend there's a static mapping here.
664 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
665 function to get the register name. That ought to be accurate.
666 However, we're changing a compile-time dependency (using the
667 REGISTER_NAMES macro) into a link- and run-time dependency
668 (calling REGISTER_NAME, which happens to be a function call on the
669 PPC).

701Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
702
703 * table.c (table_open): For cygwin hosts, we need to use the
704 return value from the read routine as the number of bytes to
705 process. This apparently is due to text-mode vs binary-mode. If
706 the mounts are done text-mode, then the size returnedby fstat()
707 may be different than the number of bytes "read" in text mode.

1103 shift + mask + test.
1104
1105 * gen-idecode.c: Correct generated igen body so that it no drops
1106 or doubles clock interrupts.
1107

1146
1147 * psim.c (psim_write_register, psim_read_register): Force the cpu
1148 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1149 next cpu would be zero any way.

1156
1157 * The code to allow an event queue to be updated during a signal
1158 was missing. For main.c, a cntrl-c simulation termination wasn't

1179 so that it is tolerant of halts.
1180 (event_queue_init): Start the event queue out with processing
1181 false.
1182 (event_queue_tick): Check that processing isn't still being
1183 performed.

1195
1196 * ppc-opcode-complex: Correct typo - was expanding ORA instead of

1198 instructions.
1199 * ppc-instructions: Change all `RA == 0' to RA_is_0.
1200
1201 * ppc-opcode-stupid: Move all but the basic table in -complex into
1202 here. Update to new format.
1203
1204 * Makefile.in (tmp-defines): New target. Force defines.h to always
1205 be built. Hence get ppc-opcode-goto to build.
1206
1207Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1208

1210 Implement.
1211
1212Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1213
1214 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1215 to be initialized independant of the rest of the simulation
1216 initalization. Otherwize a trace option explictly set from gdb
1217 could be overridden by hw_trace.
1218
1219 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1220
1221 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1222 debug.c. It could be much simpler.
1223
1224Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1225
1226 * Some devices support removable media. Add hooks to the disk

1237 media. If no file image is specified, use the next one in the
1238 image property list.
1239 (hw_disk_init_address): Change the file property so that it is a
1240 string array - use the first entry for the initial file image.
1241
1242 * tree.c (print_string_aray_property): New function - print a
1243 string array.
1244 (print_properties): Adjust.

1257
1258 * For expressions like (RA == 0) that are entered in to the cache
1259 as RA_is_0. If possible generate the result of the expression so
1260 that the compiler gets a better chance of eliminating dead
1261 branches.
1262
1263 * gen-icache.c (print_icache_extraction): For a cache entry of
1264 the form <name>_is_<const> where it is a boolean field, generate
1265 the result of the expression instead of the expression its self.
1266 (print_icache_body): Remove code that was looking for *_is_0 and
1267 then generating corresponding definitions.
1268
1269 * gen-icache.c (print_icache_struct): If there is no cache, do not
1270 output expressions in idecode.h file.
1271
1272 * gen-icache.c (print_icache_body): Output them here.
1273
1274 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1275 expansion.

1279Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1280
1281 * The code that put values in and extracted values from the cache
1282 was too compilicated. The cache table did not allow values to be
1283 computed from cache entries. #defines could only be used when a
1284 cache was present, remove the restriction.
1285
1286 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1287 scratch variable is defined when a cache entry is beinf
1288 filled. Change the definition of a COMPUTE variable to be defined
1289 when the cache entry is being used.
1290 * gen-icache.c: Update.
1291
1292 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1293 is more obvious. old_name->field_name, new_name->derived_name.
1294 * gen-icache.c: Update

2717 * : Have the generated idecode.c include inline.c (instead of psim.c).
2718
2719 * std-config.h: Change psim.c so that it isn't inlined (as this is
2720 no longer needed).
2721
2722 * psim.c (run_until_stop): Delete the old run_until_stop function
2723 instead calling the idecode_run and idecode_run_until_stop
2724 functions that gen-idecode.c is now creating.

2751 corresponding call to ITRACE so that it still matches.
2752
2753 * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead

2774 testing jumping idecodes.
2775

2790
2791 * configure.in: New option --enable-sim-line-nr (default enabled).
