605
606 Make the simulator compatible with the MPC750. It would be nicer
607 to make this a real multi-sim, but that's more work than we have
608 time for.
609 * emul_generic.c (emul_add_tree_options): Only require strict
610 alignment if it was explicitly requested at configuration time.
611 Don't make it the default for little-endian machines.
612 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
613 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
614 THRM2, THRM3): Plop in the MPC750 SPR registers.
615 (DABR): This is weird. This was HID5, but the PPC spec says this
616 should be DABR; why did some random processor use it for something
617 else? The HID5 entry dates back to the original checkin of the
618 simulator code in 1995, so remove it.
619 * sim_calls.c (register_names): Delete this; since the user can
620 now change GDB's list of register names dynamically, we can't
621 pretend there's a static mapping here.
622 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
623 function to get the register name. That ought to be accurate.
624 However, we're changing a compile-time dependency (using the
625 REGISTER_NAMES macro) into a link- and run-time dependency
626 (calling REGISTER_NAME, which happens to be a function call on the
627 PPC).
628

657 Infinities.
658
659Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
660
661 * table.c (table_open): For cygwin hosts, we need to use the
662 return value from the read routine as the number of bytes to
663 process. This apparently is due to text-mode vs binary-mode. If
664 the mounts are done text-mode, then the size returnedby fstat()
665 may be different than the number of bytes "read" in text mode.

692 * Makefile.in: The run target depended on a target psim$(EXEEXT),
693 but there was no such target, only plain psim. So I changed the
694 run target to depend on psim.
695
696Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
697
698 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are

1060 entry code so that it involves a mask + test instead of shift +
1061 shift + mask + test.
1062
1063 * gen-idecode.c: Correct generated igen body so that it no drops
1064 or doubles clock interrupts.
1065

1104
1105 * psim.c (psim_write_register, psim_read_register): Force the cpu
1106 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1107 next cpu would be zero any way.

1110 performance. This is an indication of the number of instructions
1111 per second.
1112
1113Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1114
1115 * The code to allow an event queue to be updated during a signal
1116 was missing. For main.c, a cntrl-c simulation termination wasn't
1117 handled cleanly.
1118
1119 * The simulation would not correctly restart if an event requested
1120 that the simulation be halted.
1121

1123 include a level vis -i2.
1124 (psim_usage): Document.
1125

1127 cntrl-c occures schedule an event to halt the simulation.
1128 (main): Catch CNTRL-C signals with the function cntrl_c.
1129
1130 * events.c (event_queue_process): Mask interrupts while

1134
1135 * events.c (event_queue_process): Mark the event queue as being in
1136 the processing state when processing has started. Adjust code
1137 so that it is tolerant of halts.
1138 (event_queue_init): Start the event queue out with processing
1139 false.
1140 (event_queue_tick): Check that processing isn't still being
1141 performed.
1142
1143 * gen-idecode.c (print_run_until_stop_body): Call
1144 event_queue_process_events to clear possibly pending events before

1153
1154 * ppc-opcode-complex: Correct typo - was expanding ORA instead of

1156 instructions.
1157 * ppc-instructions: Change all `RA == 0' to RA_is_0.
1158
1159 * ppc-opcode-stupid: Move all but the basic table in -complex into
1160 here. Update to new format.
1161
1162 * Makefile.in (tmp-defines): New target. Force defines.h to always
1163 be built. Hence get ppc-opcode-goto to build.
1164
1165Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1166
1167 * hw_com.c (hw_com_instance_read, hw_com_instance_write):
1168 Implement.
1169
1170Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1171
1172 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1173 to be initialized independant of the rest of the simulation
1174 initalization. Otherwize a trace option explictly set from gdb
1175 could be overridden by hw_trace.
1176
1177 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1178
1179 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1180 debug.c. It could be much simpler.
1181
1182Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1183
1184 * Some devices support removable media. Add hooks to the disk
1185 device so that it supports this.

1195 media. If no file image is specified, use the next one in the
1196 image property list.
1197 (hw_disk_init_address): Change the file property so that it is a
1198 string array - use the first entry for the initial file image.
1199
1200 * tree.c (print_string_aray_property): New function - print a
1201 string array.
1202 (print_properties): Adjust.

1213
1214Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1215
1216 * For expressions like (RA == 0) that are entered in to the cache
1217 as RA_is_0. If possible generate the result of the expression so
1218 that the compiler gets a better chance of eliminating dead
1219 branches.
1220
1221 * gen-icache.c (print_icache_extraction): For a cache entry of
1222 the form <name>_is_<const> where it is a boolean field, generate
1223 the result of the expression instead of the expression its self.
1224 (print_icache_body): Remove code that was looking for *_is_0 and
1225 then generating corresponding definitions.
1226
1227 * gen-icache.c (print_icache_struct): If there is no cache, do not
1228 output expressions in idecode.h file.
1229
1230 * gen-icache.c (print_icache_body): Output them here.
1231
1232 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1233 expansion.

1236
1237Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1238
1239 * The code that put values in and extracted values from the cache
1240 was too compilicated. The cache table did not allow values to be
1241 computed from cache entries. #defines could only be used when a
1242 cache was present, remove the restriction.
1243
1244 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1245 scratch variable is defined when a cache entry is beinf
1246 filled. Change the definition of a COMPUTE variable to be defined
1247 when the cache entry is being used.
1248 * gen-icache.c: Update.
1249
1250 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1251 is more obvious. old_name->field_name, new_name->derived_name.
1252 * gen-icache.c: Update
1253
1254 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1255 different types of cache code - put into cache, extract from
1256 cache, no cache - an explicit argument to print_icache_body.
1257 * gen-icache.c (print_icache_extraction): Ditto.
1258
1259 * gen-semantics.c (print_c_semantic): Update use.
1260 * gen-idecode.c (print_jump_insn): Update use.
1261 * gen-icache.c (print_icache_function): Update use.
1262
1263 * igen.c (main): Change 'R' option so that it does not force the
1264 cache.
1265
1266 * configure.in (enable-sim-icache): Clarify description. Make
1267 #define one of the defaults regardless of the cache. Probably
1268 should revamp and add a separate option.
1269
1270Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1271

1275 1..3.
1276 (is_iso9660): New function, verify a CD9660 File system.
1277 (pk_disklabel_create_instance): Start expanding so that active
1278 partition selection is supported.

1280Mon Jan 20 11:20:15 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1281
1282 * The cap object was retaining a reference to the instance of a
1283 device after it was deleted. Instead add and remove cap's from the
1284 cap db as they are created and deleted. This ensuring that a
1285 capibility is only used during the lifetime of the corresponding
1286 object.
1287
1288 * cap.h, cap.c: Correct cap type - was signed32 should be
1289 signed_cell.
1290
1291 * cap.c (cap_add, cap_remove): New methods for cap object that
1292 allow the explicit addition and removal of internal objects that
1293 the cap knows about.
1294
1295 * cap.c (cap_init): Rewrite. Verify that the only objects
1296 remaining in the cap data base are those that were entered first.
1297 Thse objects will be the permenant ones.
1298 * device.c (device_init_address): Remember to initialize the cap
