553 after the specified POLL_QUIT_INTERVAL.

566
567 Make the simulator compatible with the MPC750. It would be nicer
568 to make this a real multi-sim, but that's more work than we have
569 time for.
570 * emul_generic.c (emul_add_tree_options): Only require strict
571 alignment if it was explicitly requested at configuration time.
572 Don't make it the default for little-endian machines.
573 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
574 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
575 THRM2, THRM3): Plop in the MPC750 SPR registers.
576 (DABR): This is weird. This was HID5, but the PPC spec says this
577 should be DABR; why did some random processor use it for something
578 else? The HID5 entry dates back to the original checkin of the
579 simulator code in 1995, so remove it.
580 * sim_calls.c (register_names): Delete this; since the user can
581 now change GDB's list of register names dynamically, we can't
582 pretend there's a static mapping here.
583 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
584 function to get the register name. That ought to be accurate.
585 However, we're changing a compile-time dependency (using the
586 REGISTER_NAMES macro) into a link- and run-time dependency
587 (calling REGISTER_NAME, which happens to be a function call on the
588 PPC).
589
5901999-01-22 Jim Lemke <jlemke@cygnus.com>
591
592 * igen.c(gen_semantics_[ch]): setup/use of new option

597 These changes are currently under #ifdef WITH_OPTION_MPC860C0.

616 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
617 fractional type, so that quiet NaN's aren't treated like
618 Infinities.
619
620Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
621
622 * table.c (table_open): For cygwin hosts, we need to use the
623 return value from the read routine as the number of bytes to
624 process. This apparently is due to text-mode vs binary-mode. If
625 the mounts are done text-mode, then the size returnedby fstat()
626 may be different than the number of bytes "read" in text mode.
627
628Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>

652
653 * Makefile.in: The run target depended on a target psim$(EXEEXT),
654 but there was no such target, only plain psim. So I changed the
655 run target to depend on psim.
656
657Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
658
659 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
660 now defined in ../common/aclocal.m4, and the double definition causes

961 don't assume void.
962 * sim_calls.c (sim_{ctrl_c,resume}): Ditto.
963
964 * Makefile.in (callback.o): Define HAVE_CONFIG_H, so callback.c

991
992 * gen-icache.c (print_icache_extraction): Add a reason parameter.
993 Augment each extracted field with a comment citing the codes
994 origin. Should simplify tracking down incorrect cache
995 extractions.
996
997Tue Feb 4 17:44:51 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
998

1000 works for normal and boolean table entries.
1001
1002 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now

1018
1019 * gen-idecode.c: Re-work the table lookup code so that it assumes
1020 that the entry is a leaf by default. Simplify the boolean table
1021 entry code so that it involves a mask + test instead of shift +
1022 shift + mask + test.
1023
1024 * gen-idecode.c: Correct generated igen body so that it no drops
1025 or doubles clock interrupts.
1026

1054 fields.
1055
1056 * misc.c (name2i): Possibly abort if an invalid name is
1057 encountered.
1058 * ld-decode.c: Abort if the table type isn't found.

1065
1066 * psim.c (psim_write_register, psim_read_register): Force the cpu
1067 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1068 next cpu would be zero any way.
1069
1070 * mon.c (mon_print_info): If possible, print the system cycle
1071 performance. This is an indication of the number of instructions
1072 per second.
1073
1074Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1075
1076 * The code to allow an event queue to be updated during a signal
1077 was missing. For main.c, a cntrl-c simulation termination wasn't
1078 handled cleanly.
1079
1080 * The simulation would not correctly restart if an event requested
1081 that the simulation be halted.
1082
1083 * psim.c (psim_options): Add hack to -i option to optionally
1084 include a level vis -i2.
1085 (psim_usage): Document.
1086
1087 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a
1088 cntrl-c occures schedule an event to halt the simulation.
1089 (main): Catch CNTRL-C signals with the function cntrl_c.
1090
1091 * events.c (event_queue_process): Mask interrupts while
1092 manipulating the async event queue.
1093 (event_queue_init): Ditto.
1094 (event_queue_schedule_after_signal): Ditto.
1095
1096 * events.c (event_queue_process): Mark the event queue as being in
1097 the processing state when processing has started. Adjust code
1098 so that it is tolerant of halts.
1099 (event_queue_init): Start the event queue out with processing
1100 false.
1101 (event_queue_tick): Check that processing isn't still being
1102 performed.
1103
1104 * gen-idecode.c (print_run_until_stop_body): Call
1105 event_queue_process_events to clear possibly pending events before
1106 starting a simulation run. Re-arange main loop so that simulator
1107 is correctly restarted when an event halts the simulation.

1109 * psim.c (psim_halt): Handle an event halting the simulation.
1110 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1111 reworked idecode.
1112
1113Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1114
1115 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1116 RA. Based on instruction frequency stats, expand additional
1117 instructions.
1118 * ppc-instructions: Change all `RA == 0' to RA_is_0.
1119
1120 * ppc-opcode-stupid: Move all but the basic table in -complex into
1121 here. Update to new format.
1122
1123 * Makefile.in (tmp-defines): New target. Force defines.h to always
1124 be built. Hence get ppc-opcode-goto to build.
1125
1126Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1127
1128 * hw_com.c (hw_com_instance_read, hw_com_instance_write):
1129 Implement.
1130
1131Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1132
1133 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1134 to be initialized independant of the rest of the simulation
1135 initalization. Otherwize a trace option explictly set from gdb
1136 could be overridden by hw_trace.
1137
1138 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1139
1140 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1141 debug.c. It could be much simpler.
1142
1143Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1144
1145 * Some devices support removable media. Add hooks to the disk
1146 device so that it supports this.
1147
1148 * device.c (device_add_string_array_property,
1149 device_find_string_array_property): New functions, manipulate
1150 properties containing an array of strings.

1156 media. If no file image is specified, use the next one in the
1157 image property list.
1158 (hw_disk_init_address): Change the file property so that it is a
1159 string array - use the first entry for the initial file image.
1160
1161 * tree.c (print_string_aray_property): New function - print a
1162 string array.
1163 (print_properties): Adjust.
1164 (print_string): Write a string, handling double quotes.
1165
1166 * device.h: Define an ioctl to `change-media' with an optional new
1167 media image.
1168
1169 * hw_disk.c: Allow floppy disk devices to be specified.
1170
1171 * psim.c (psim_command): New function, parse more complex psim
1172 commands such as "change-media" and "trace".
1173 * sim_calls.c (sim_do_command): Use.
1174
1175Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1176
1177 * For expressions like (RA == 0) that are entered in to the cache
1178 as RA_is_0. If possible generate the result of the expression so
1179 that the compiler gets a better chance of eliminating dead
1180 branches.
1181
1182 * gen-icache.c (print_icache_extraction): For a cache entry of
1183 the form <name>_is_<const> where it is a boolean field, generate
1184 the result of the expression instead of the expression its self.
1185 (print_icache_body): Remove code that was looking for *_is_0 and
1186 then generating corresponding definitions.
1187
1188 * gen-icache.c (print_icache_struct): If there is no cache, do not
1189 output expressions in idecode.h file.
1190
1191 * gen-icache.c (print_icache_body): Output them here.
1192
1193 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1194 expansion.

1197
1198Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1199
1200 * The code that put values in and extracted values from the cache
1201 was too compilicated. The cache table did not allow values to be
1202 computed from cache entries. #defines could only be used when a
1203 cache was present, remove the restriction.
1204
1205 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1206 scratch variable is defined when a cache entry is beinf
1207 filled. Change the definition of a COMPUTE variable to be defined
1208 when the cache entry is being used.
1209 * gen-icache.c: Update.
1210
1211 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1212 is more obvious. old_name->field_name, new_name->derived_name.
1213 * gen-icache.c: Update
1214
1215 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1216 different types of cache code - put into cache, extract from
1217 cache, no cache - an explicit argument to print_icache_body.
1218 * gen-icache.c (print_icache_extraction): Ditto.
1219
1220 * gen-semantics.c (print_c_semantic): Update use.
1221 * gen-idecode.c (print_jump_insn): Update use.
1222 * gen-icache.c (print_icache_function): Update use.
1223
1224 * igen.c (main): Change 'R' option so that it does not force the
1225 cache.
1226
1227 * configure.in (enable-sim-icache): Clarify description. Make
1228 #define one of the defaults regardless of the cache. Probably
1229 should revamp and add a separate option.
1230
1231Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1232
1233 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
1234 partition numbering.

1236 1..3.
1237 (is_iso9660): New function, verify a CD9660 File system.
1238 (pk_disklabel_create_instance): Start expanding so that active
1239 partition selection is supported.

1241Mon Jan 20 11:20:15 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1242
1243 * The cap object was retaining a reference to the instance of a
1244 device after it was deleted. Instead add and remove cap's from the
1245 cap db as they are created and deleted. This ensuring that a
1246 capibility is only used during the lifetime of the corresponding
1247 object.
1248
1249 * cap.h, cap.c: Correct cap type - was signed32 should be
1250 signed_cell.
1251
1252 * cap.c (cap_add, cap_remove): New methods for cap object that
1253 allow the explicit addition and removal of internal objects that
1254 the cap knows about.
1255
1256 * cap.c (cap_init): Rewrite. Verify that the only objects
1257 remaining in the cap data base are those that were entered first.
1258 Thse objects will be the permenant ones.
1259 * device.c (device_init_address): Remember to initialize the cap
1260 database.
1261
1262 * device.c (device_create_instance_from): Explicitly add device
1263 instances to the cap database. Simplify create code.
1264 (device_instance_delete): Explicitly remove device instances from

1280Sun Jan 19 15:28:23 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1281
1282 * The memory "claim" and "release" methods take an address and
1283 size as arguments. These may be multi cell values. Initially fix
1284 the memory code so that they check/detect this. Leave the
1285 adjustment of any clients to later.
1286
1287 * hw_memory.c (hw_memory_instance_claim,
1288 hw_memory_instance_release): Handle multi-cell memory devices.
1289
1290 * hw_memory.c (hw_memory_instance_claim): Be tolerant towards the

1292
1293Fri Jan 17 12:01:07 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1294
1295 * device.h, device.c (device_instance_call_method): Correct return
1296 type - can return either 0 or -1, hence should be a signed type.
1297 * device_table.h: Ditto.
1298
1299 * hw_memory.c (hw_memory_instance_claim,
1300 hw_memory_instance_release): Update.
