556 Make the simulator compatible with the MPC750. It would be nicer
557 to make this a real multi-sim, but that's more work than we have
558 time for.
559 * emul_generic.c (emul_add_tree_options): Only require strict
560 alignment if it was explicitly requested at configuration time.
561 Don't make it the default for little-endian machines.
562 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
563 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
564 THRM2, THRM3): Plop in the MPC750 SPR registers.
565 (DABR): This is weird. This was HID5, but the PPC spec says this
566 should be DABR; why did some random processor use it for something
567 else? The HID5 entry dates back to the original checkin of the
568 simulator code in 1995, so remove it.
569 * sim_calls.c (register_names): Delete this; since the user can
570 now change GDB's list of register names dynamically, we can't
571 pretend there's a static mapping here.
572 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
573 function to get the register name. That ought to be accurate.
574 However, we're changing a compile-time dependency (using the
575 REGISTER_NAMES macro) into a link- and run-time dependency
576 (calling REGISTER_NAME, which happens to be a function call on the
577 PPC).

609Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
610
611 * table.c (table_open): For cygwin hosts, we need to use the
612 return value from the read routine as the number of bytes to
613 process. This apparently is due to text-mode vs binary-mode. If
614 the mounts are done text-mode, then the size returnedby fstat()
615 may be different than the number of bytes "read" in text mode.

950 don't assume void.
951 * sim_calls.c (sim_{ctrl_c,resume}): Ditto.
952
953 * Makefile.in (callback.o): Define HAVE_CONFIG_H, so callback.c

955
956Tue Feb 4 13:42:59 1997 Doug Evans <dje@canuck.cygnus.com>
957
958 * configure.in: Fix typo in test for callback.c.

980
981 * gen-icache.c (print_icache_extraction): Add a reason parameter.
982 Augment each extracted field with a comment citing the codes
983 origin. Should simplify tracking down incorrect cache
984 extractions.
985
986Tue Feb 4 17:44:51 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
987

989 works for normal and boolean table entries.
990
991 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
992 valid. Handle this just like *_{read,write}_register now handles

1007
1008 * gen-idecode.c: Re-work the table lookup code so that it assumes
1009 that the entry is a leaf by default. Simplify the boolean table
1010 entry code so that it involves a mask + test instead of shift +
1011 shift + mask + test.
1012
1013 * gen-idecode.c: Correct generated igen body so that it no drops
1014 or doubles clock interrupts.
1015
1016

1043 fields.
1044
1045 * misc.c (name2i): Possibly abort if an invalid name is
1046 encountered.
1047 * ld-decode.c: Abort if the table type isn't found.

1053 ticks recorded by the event queue.
1054
1055 * psim.c (psim_write_register, psim_read_register): Force the cpu
1056 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1057 next cpu would be zero any way.

1059 * mon.c (mon_print_info): If possible, print the system cycle
1060 performance. This is an indication of the number of instructions
1061 per second.
1062
1063Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1064
1065 * The code to allow an event queue to be updated during a signal
1066 was missing. For main.c, a cntrl-c simulation termination wasn't
1067 handled cleanly.
1068
1069 * The simulation would not correctly restart if an event requested
1070 that the simulation be halted.
1071
1072 * psim.c (psim_options): Add hack to -i option to optionally
1073 include a level vis -i2.
1074 (psim_usage): Document.
1075
1076 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a
1077 cntrl-c occures schedule an event to halt the simulation.
1078 (main): Catch CNTRL-C signals with the function cntrl_c.
1079
1080 * events.c (event_queue_process): Mask interrupts while
1081 manipulating the async event queue.
1082 (event_queue_init): Ditto.
1083 (event_queue_schedule_after_signal): Ditto.
1084
1085 * events.c (event_queue_process): Mark the event queue as being in
1086 the processing state when processing has started. Adjust code
1087 so that it is tolerant of halts.
1088 (event_queue_init): Start the event queue out with processing
1089 false.
1090 (event_queue_tick): Check that processing isn't still being
1091 performed.
1092
1093 * gen-idecode.c (print_run_until_stop_body): Call
1094 event_queue_process_events to clear possibly pending events before
1095 starting a simulation run. Re-arange main loop so that simulator
1096 is correctly restarted when an event halts the simulation.

1098 * psim.c (psim_halt): Handle an event halting the simulation.
1099 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1100 reworked idecode.
1101
1102Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1103
1104 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1105 RA. Based on instruction frequency stats, expand additional
1106 instructions.
1107 * ppc-instructions: Change all `RA == 0' to RA_is_0.
1108
1109 * ppc-opcode-stupid: Move all but the basic table in -complex into
1110 here. Update to new format.
1111
1112 * Makefile.in (tmp-defines): New target. Force defines.h to always
1113 be built. Hence get ppc-opcode-goto to build.
1114
1115Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1116
1117 * hw_com.c (hw_com_instance_read, hw_com_instance_write):
1118 Implement.
1119
1120Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1121
1122 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1123 to be initialized independant of the rest of the simulation
1124 initalization. Otherwize a trace option explictly set from gdb
1125 could be overridden by hw_trace.
1126
1127 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1128
1129 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1130 debug.c. It could be much simpler.
1131
1132Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1133
1134 * Some devices support removable media. Add hooks to the disk
1135 device so that it supports this.
1136
1137 * device.c (device_add_string_array_property,
1138 device_find_string_array_property): New functions, manipulate
1139 properties containing an array of strings.

1145 media. If no file image is specified, use the next one in the
1146 image property list.
1147 (hw_disk_init_address): Change the file property so that it is a
1148 string array - use the first entry for the initial file image.
1149
1150 * tree.c (print_string_aray_property): New function - print a
1151 string array.
1152 (print_properties): Adjust.
1153 (print_string): Write a string, handling double quotes.
1154
1155 * device.h: Define an ioctl to `change-media' with an optional new
1156 media image.
1157
1158 * hw_disk.c: Allow floppy disk devices to be specified.
1159
1160 * psim.c (psim_command): New function, parse more complex psim
1161 commands such as "change-media" and "trace".
1162 * sim_calls.c (sim_do_command): Use.
1163
1164Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1165
1166 * For expressions like (RA == 0) that are entered in to the cache
1167 as RA_is_0. If possible generate the result of the expression so
1168 that the compiler gets a better chance of eliminating dead
1169 branches.
1170
1171 * gen-icache.c (print_icache_extraction): For a cache entry of
1172 the form <name>_is_<const> where it is a boolean field, generate
1173 the result of the expression instead of the expression its self.
1174 (print_icache_body): Remove code that was looking for *_is_0 and
1175 then generating corresponding definitions.
1176
1177 * gen-icache.c (print_icache_struct): If there is no cache, do not
1178 output expressions in idecode.h file.
1179
1180 * gen-icache.c (print_icache_body): Output them here.
1181
1182 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1183 expansion.

1186
1187Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1188
1189 * The code that put values in and extracted values from the cache
1190 was too compilicated. The cache table did not allow values to be
1191 computed from cache entries. #defines could only be used when a
1192 cache was present, remove the restriction.
1193
1194 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1195 scratch variable is defined when a cache entry is beinf
1196 filled. Change the definition of a COMPUTE variable to be defined
1197 when the cache entry is being used.
1198 * gen-icache.c: Update.
1199
1200 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1201 is more obvious. old_name->field_name, new_name->derived_name.
1202 * gen-icache.c: Update
1203
1204 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1205 different types of cache code - put into cache, extract from
1206 cache, no cache - an explicit argument to print_icache_body.
1207 * gen-icache.c (print_icache_extraction): Ditto.
1208
1209 * gen-semantics.c (print_c_semantic): Update use.
1210 * gen-idecode.c (print_jump_insn): Update use.
1211 * gen-icache.c (print_icache_function): Update use.
1212
1213 * igen.c (main): Change 'R' option so that it does not force the
1214 cache.
1215
1216 * configure.in (enable-sim-icache): Clarify description. Make
1217 #define one of the defaults regardless of the cache. Probably
1218 should revamp and add a separate option.
1219
1220Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1221
1222 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
1223 partition numbering.

1230Mon Jan 20 11:20:15 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1231
1232 * The cap object was retaining a reference to the instance of a
1233 device after it was deleted. Instead add and remove cap's from the
1234 cap db as they are created and deleted. This ensuring that a
1235 capibility is only used during the lifetime of the corresponding
1236 object.
1237
1238 * cap.h, cap.c: Correct cap type - was signed32 should be
1239 signed_cell.
1240
1241 * cap.c (cap_add, cap_remove): New methods for cap object that
1242 allow the explicit addition and removal of internal objects that
1243 the cap knows about.
1244
1245 * cap.c (cap_init): Rewrite. Verify that the only objects
1246 remaining in the cap data base are those that were entered first.
1247 Thse objects will be the permenant ones.
1248 * device.c (device_init_address): Remember to initialize the cap
1249 database.
1250
1251 * device.c (device_create_instance_from): Explicitly add device
1252 instances to the cap database. Simplify create code.
1253 (device_instance_delete): Explicitly remove device instances from

1269Sun Jan 19 15:28:23 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1270
1271 * The memory "claim" and "release" methods take an address and
1272 size as arguments. These may be multi cell values. Initially fix
1273 the memory code so that they check/detect this. Leave the
1274 adjustment of any clients to later.
1275
1276 * hw_memory.c (hw_memory_instance_claim,
1277 hw_memory_instance_release): Handle multi-cell memory devices.

1281
1282Fri Jan 17 12:01:07 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1283
1284 * device.h, device.c (device_instance_call_method): Correct return
1285 type - can return either 0 or -1, hence should be a signed type.
1286 * device_table.h: Ditto.
1287
1288 * hw_memory.c (hw_memory_instance_claim,
1289 hw_memory_instance_release): Update.

1297 (chirm_emul_release): Ditto.
1298
1299 * Makefile.in (LIB_INLINE_SRC): Remove emul_* from list of files
1300 that are inlined. These modules are called via a table and are
1301 not made inline.
1302
