656
1999-02-01  Jim Blandy  
657
 
658
        Make the simulator compatible with the MPC750.  It would be nicer
659
        to make this a real multi-sim, but that's more work than we have
660
        time for.
661
        * emul_generic.c (emul_add_tree_options): Only require strict
662
        alignment if it was explicitly requested at configuration time.
663
        Don't make it the default for little-endian machines.
664
        * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
665
        MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
666
        THRM2, THRM3): Plop in the MPC750 SPR registers.
667
        (DABR): This is weird.  This was HID5, but the PPC spec says this
668
        should be DABR; why did some random processor use it for something
669
        else?  The HID5 entry dates back to the original checkin of the
670
        simulator code in 1995, so remove it.
671
        * sim_calls.c (register_names): Delete this; since the user can
672
        now change GDB's list of register names dynamically, we can't
673
        pretend there's a static mapping here.
674
        (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
675
        function to get the register name.  That ought to be accurate.
676
        However, we're changing a compile-time dependency (using the
677
        REGISTER_NAMES macro) into a link- and run-time dependency
678
        (calling REGISTER_NAME, which happens to be a function call on the
679
        PPC).

716
        the mounts are done text-mode, then the size returnedby fstat()
717
        may be different than the number of bytes "read" in text mode.

        (even_queue_{init,schedule_after_signal,tick}): Conditionalize use
1049
        of sigprocmask to appropriate autoconf test.
1050
 
1051
        * main.c ({cntrl_c,main}): Use RETSIGTYPE for signal return type,
1052
        don't assume void.

1054
 
1055
        * Makefile.in (callback.o): Define HAVE_CONFIG_H, so callback.c
1056
        includes our config.h.

        found in the device tree.
1067
 
1068
Wed Feb  5 10:56:27 1997  Andrew Cagney  
1069
 
1070
        * Property create/initialization still wasn't correctly ordered.
1071
        Should be delaying everything related to ihandle creation until
1072
        after the rest of the tree has been established.
1073
 
1074
        * device.c (device_find_ihandle_runtime_property): Update.
1075
        (device_add_ihandle_runtime_property): Update.
1076
 
1077
        * tree.c (parse_ihandle_property): Delay lookup of the device to

        * tree.c (print_properties): Update.
1080
 
1081
Wed Feb  5 10:56:27 1997  Andrew Cagney  
1082
 
1083
        * gen-icache.c (print_icache_extraction): Add a reason parameter.
1084
        Augment each extracted field with a comment citing the codes
1085

        extractions.
1087
 
1088

1089
 
1090
        * gen-icache.c: Generalize code handling XXX_is_NNN so that it
1091
        works for normal and boolean table entries.
1092
 
1093
        * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
1094
        valid.  Handle this just like *_{read,write}_register now handles
1095
        it.
1096
 
1097
Mon Feb  3 17:18:16 1997  Andrew Cagney  
1098
 
1099
        * events.c (insert_event_entry): Correct loop termination
1100
        assertions.
1101
 
1102
Fri Jan 31 16:20:26 1997  Andrew Cagney  
1103
 
1104
        * psim.c (psim_options): Add new option -c for max-iterations or
1105
        count.
1106
        (psim_usage): Document.

        (psim_max_iterations_exceeded): New function, abort simulation if
1108
        max iterations exceeded.
1109
 
1110
        * gen-idecode.c: Re-work the table lookup code so that it assumes
1111
        that the entry is a leaf by default.  Simplify the boolean table
1112
        entry code so that it involves a mask + test instead of shift +
1113
        shift + mask + test.
1114
 
1115
        * gen-idecode.c: Correct generated igen body so that it no drops
1116
        or doubles clock interrupts.
1117
 
1118
 
1119
Thu Jan 30 11:23:20 1997  Andrew Cagney  
1120
 
1121
        * Makefile.in (BUILT_SRC_WO_CONFIG): Change targ-vals.* to

1130
        callback support from the common directory.
1131
        * configure: Regenerate.

1135
        (GDB_OBJ): Add callback support configured in.
1136
        (gentmap,targ-vals.def): Build from common directory.
1137
        (targ-vals.h,targ-map.c): Build by running gentmap.
1138
        (callback.o): Build from source in common directory.
1139
        (targ-map.o): Add dependency.
1140

1141
 
1142
Wed Jan 29 12:14:19 1997  Andrew Cagney  
1143
 
1144
        * igen wasn't aborting if the opcode table contained no valid
1145
        fields.
1146
 
1147
        * misc.c (name2i): Possibly abort if an invalid name is
1148
        encountered.
1149
        * ld-decode.c: Abort if the table type isn't found.
1150
 
1151
Wed Jan 29 12:14:19 1997  Andrew Cagney  
1152
 
1153
        * When performance monitoring is disabled, it is still possible to
1154
        determine the simulation speed by looking at the number of elapsed
1155
        ticks recorded by the event queue.
1156
 
1157
        * psim.c (psim_write_register, psim_read_register): Force the cpu
1158
        to zero when it is either of `-1' or `nr_cpus'.  In both cases the
1159
        next cpu would be zero any way.
1160
 
1161
        * mon.c (mon_print_info): If possible, print the system cycle
1162
        performance.  This is an indication of the number of instructions
1163
        per second.
1164
 
1165
Wed Jan 29 12:14:19 1997  Andrew Cagney  
1166
 
1167
        * The code to allow an event queue to be updated during a signal
1168
        was missing.  For main.c, a cntrl-c simulation termination wasn't
1169
        handled cleanly.
1170
 
1171
        * The simulation would not correctly restart if an event requested
1172
        that the simulation be halted.
1173
 
1174
        * psim.c (psim_options): Add hack to -i option to optionally
1175
        include a level vis -i2.

        (psim_usage): Document.
1177
 
1178
        * main.c (cntrl_c, cntrl_c_simulation): New functions.  When a
1179
        cntrl-c occures schedule an event to halt the simulation.
1180
        (main): Catch CNTRL-C signals with the function cntrl_c.
1181
 
1182
        * events.c (event_queue_process): Mask interrupts while
1183
        manipulating the async event queue.
1184
        (event_queue_init): Ditto.
1185
        (event_queue_schedule_after_signal): Ditto.
1186
 
1187
        * events.c (event_queue_process): Mark the event queue as being in
1188
        the processing state when processing has started.  Adjust code
1189
        so that it is tolerant of halts.
1190
        (event_queue_init): Start the event queue out with processing
1191
        false.
1192
        (event_queue_tick): Check that processing isn't still being
1193
        performed.
1194
 
1195
        * gen-idecode.c (print_run_until_stop_body): Call
1196
        event_queue_process_events to clear possibly pending events before
1197
        starting a simulation run.  Re-arange main loop so that simulator
1198
        is correctly restarted when an event halts the simulation.
1199
 
1200
        * psim.c (psim_halt): Handle an event halting the simulation.
1201
        * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1202
        reworked idecode.
1203
 
1204
Wed Jan 29 12:14:19 1997  Andrew Cagney  
1205
 
1206
        * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1207
        RA.  Based on instruction frequency stats, expand additional
1208
        instructions.
1209
        * ppc-instructions: Change all `RA == 0' to RA_is_0.
1210
 
1211
        * ppc-opcode-stupid: Move all but the basic table in -complex into
1212
        here.  Update to new format.
1213
 
1214
        * Makefile.in (tmp-defines): New target. Force defines.h to always
1215
        be built.  Hence get ppc-opcode-goto to build.
1216
 
1217
Tue Jan 28 13:00:19 1997  Andrew Cagney  
1218
 
1219
        * hw_com.c (hw_com_instance_read, hw_com_instance_write):
1220
        Implement.
1221
 
1222
Thu Jan 23 09:07:26 1997  Andrew Cagney  
1223
 
1224
        * hw_trace.c (hw_trace_init_data): Delete.  The trace options need
1225
        to be initialized independant of the rest of the simulation
1226
        initalization.  Otherwize a trace option explictly set from gdb
1227
        could be overridden by hw_trace.
1228
 
1229
        * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1230
 
1231
        * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1232
        debug.c.  It could be much simpler.
1233
 
1234
Thu Jan 23 09:07:26 1997  Andrew Cagney  
1235
 
1236
        * Some devices support removable media.  Add hooks to the disk
1237
        device so that it supports this.
1238
 
1239
        * device.c (device_add_string_array_property,
1240
        device_find_string_array_property): New functions, manipulate

        (device_init_runtime_properties): Update.
1245
 
1246
        * hw_disk.c (hw_disk_ioctl): Add ioctl for changing the disk
1247
        media.  If no file image is specified, use the next one in the
1248
        image property list.
1249
        (hw_disk_init_address): Change the file property so that it is a
1250
        string array - use the first entry for the initial file image.
1251
 
1252
        * tree.c (print_string_aray_property): New function - print a
1253
        string array.
1254
        (print_properties): Adjust.
1255
        (print_string): Write a string, handling double quotes.
1256
 
1257
        * device.h: Define an ioctl to `change-media' with an optional new
1258
        media image.
1259
 
1260
        * hw_disk.c: Allow floppy disk devices to be specified.
1261
 
1262
        * psim.c (psim_command): New function, parse more complex psim
1263
        commands such as "change-media" and "trace".
1264
        * sim_calls.c (sim_do_command): Use.
1265
 
1266
Wed Jan 22 09:38:33 1997  Andrew Cagney  
1267
 
1268
        * For expressions like (RA == 0) that are entered in to the cache
1269
        as RA_is_0. If possible generate the result of the expression so
1270
        that the compiler gets a better chance of eliminating dead
1271
        branches.
1272
 
1273
        * gen-icache.c (print_icache_extraction): For a cache entry of
1274
        the form _is_ where it is a boolean field, generate
1275
        the result of the expression instead of the expression its self.
1276
        (print_icache_body): Remove code that was looking for *_is_0 and
1277
        then generating corresponding definitions.
1278
 
1279
        * gen-icache.c (print_icache_struct): If there is no cache, do not
1280
        output expressions in idecode.h file.
1281
 
1282
        * gen-icache.c (print_icache_body): Output them here.
1283
 
1284
        * ppc-opcode-complex: Clarify constant values for SPR==LR register
1285
        expansion.
1286
 
1287
        * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
1288
 
1289
Wed Jan 22 12:24:52 1997  Andrew Cagney  
1290
 
1291
        * The code that put values in and extracted values from the cache
1292
        was too compilicated.  The cache table did not allow values to be
1293
        computed from cache entries.  #defines could only be used when a
1294
        cache was present, remove the restriction.
1295
 
1296
        * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH.  A
1297
        scratch variable is defined when a cache entry is beinf
1298
        filled. Change the definition of a COMPUTE variable to be defined
1299
        when the cache entry is being used.
1300
        * gen-icache.c: Update.
1301
 
1302
        * ld-cache.h, ld-cache.c: Change field names so that their meaning
1303
        is more obvious.  old_name->field_name, new_name->derived_name.
1304
        * gen-icache.c: Update
1305
 
1306
        * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1307
        different types of cache code - put into cache, extract from
1308
        cache, no cache - an explicit argument to print_icache_body.
1309
        * gen-icache.c (print_icache_extraction): Ditto.
1310
 
1311
        * gen-semantics.c (print_c_semantic): Update use.
1312

1316
        cache.
1317
 
1318
        * configure.in (enable-sim-icache): Clarify description.  Make
1319
        #define one of the defaults regardless of the cache.  Probably
1320
        should revamp and add a separate option.
1321

Tue Jan 21 13:26:10 1997  Andrew Cagney  
1323
 
1324
        * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
1325
        partition numbering.
1326
        (pk_disklabel_create_instance): Partition 1..4 are valid - not
1327
        1..3.
1328
        (is_iso9660): New function, verify a CD9660 File system.
1329
        (pk_disklabel_create_instance): Start expanding so that active
1330
        partition selection is supported.
1331
 
1332
Mon Jan 20 11:20:15 1997  Andrew Cagney  
1333
 
1334
        * The cap object was retaining a reference to the instance of a
1335
        device after it was deleted. Instead add and remove cap's from the
1336
        cap db as they are created and deleted.  This ensuring that a
1337
        capibility is only used during the lifetime of the corresponding
1338
        object.
1339
 
1340
        * cap.h, cap.c: Correct cap type - was signed32 should be
1341
        signed_cell.
1342
 
1343
        * cap.c (cap_add, cap_remove): New methods for cap object that
1344
        allow the explicit addition and removal of internal objects that
1345
        the cap knows about.
1346
 
1347
        * cap.c (cap_init): Rewrite.  Verify that the only objects
1348
        remaining in the cap data base are those that were entered first.
1349
        Thse objects will be the permenant ones.
1350
        * device.c (device_init_address): Remember to initialize the cap
1351
        database.
1352
 
1353
        * device.c (device_create_instance_from): Explicitly add device

1371
Sun Jan 19 15:28:23 1997  Andrew Cagney  
1372
 
1373
        * The memory "claim" and "release" methods take an address and
1374
        size as arguments.  These may be multi cell values. Initially fix
1375
        the memory code so that they check/detect this.  Leave the
1376
        adjustment of any clients to later.
1377
 
1378
        * hw_memory.c (hw_memory_instance_claim,

1385
 
1386
        * device.h, device.c (device_instance_call_method): Correct return

2635
        when generating illegal instructions.  This was commented out

2679
 
2680
        * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and

2728
 
2729
        * std-config.h: Change psim.c so that it isn't inlined (as this is
