703
        time_from_event implies an empty event queue.

721
1999-05-08  Felix Lee  
722

726
1999-04-02  Keith Seitz  
727
 
728
        * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
729
        the frequency at which the poll_quit callback is called.
730
        (poll_quit_count): New global.
731
        (sim_io_poll_quit): Only call the poll_quit callback
732
        after the specified POLL_QUIT_INTERVAL.
733
 
734
1999-02-22  Jim Lemke  
735
 
736
        * dc-complex: Force expansion on all bits of field BO.
737
        Previously, the least-significant (prediction) bit was ignored.
738
        * ppc-instructions (conditional branches): Implement mpc860c0 option.
739
        * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
740
        * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.
741
        * interrupts.h: Added "mpc860c0_instruction_program_interrupt".
742
        * interrupts.c (program_interrupt): Added handling for above interrupt.
743
 
744
1999-02-01  Jim Blandy  
745
 
746
        Make the simulator compatible with the MPC750.  It would be nicer
747
        to make this a real multi-sim, but that's more work than we have
748
        time for.
749
        * emul_generic.c (emul_add_tree_options): Only require strict
750
        alignment if it was explicitly requested at configuration time.
751
        Don't make it the default for little-endian machines.
752
        * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
753
        MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
754
        THRM2, THRM3): Plop in the MPC750 SPR registers.
755
        (DABR): This is weird.  This was HID5, but the PPC spec says this
756
        should be DABR; why did some random processor use it for something
757
        else?  The HID5 entry dates back to the original checkin of the
758
        simulator code in 1995, so remove it.
759
        * sim_calls.c (register_names): Delete this; since the user can
760
        now change GDB's list of register names dynamically, we can't
761
        pretend there's a static mapping here.
762
        (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
763
        function to get the register name.  That ought to be accurate.
764
        However, we're changing a compile-time dependency (using the
765
        REGISTER_NAMES macro) into a link- and run-time dependency
766
        (calling REGISTER_NAME, which happens to be a function call on the
767
        PPC).
768
 
769
1999-01-22  Jim Lemke 
770
 
771
        * igen.c(gen_semantics_[ch]): setup/use of new option
772
        (-o mpc860c0[=n]).
773
        interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
774
        ppc-instructions(the four branch insn groups): detect problematic br's.
775
        psim.c(is_num - added, psim_options): Parse and init new option.
776
        These changes are currently under #ifdef WITH_OPTION_MPC860C0.
777
 
778
1998-12-01  Ken Raeburn  
779
 
780

        * main.c (sim_io_poll_quit): Stub function.
785
 
786
        * events.c (SIM_EVENTS_POLL_RATE): Define.
787
        (sim_events_poll): Copy function from common/sim-events.c.
788
        (event_queue_init): Copy scheduling of sim_events_poll from same.
789
 
790
        * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
791
        poll the external environment.
792
 
793
1998-11-19  Michael Meissner  
794
 
795
        * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
796
        fractional type, so that quiet NaN's aren't treated like
797
        Infinities.
798
 
799
Mon Sep 28 09:42:45 1998  Drew Moseley  
800
 
801
        * table.c (table_open): For cygwin hosts, we need to use the
802
        return value from the read routine as the number of bytes to
803
        process.  This apparently is due to text-mode vs binary-mode.  If
804
        the mounts are done text-mode, then the size returnedby fstat()
805
        may be different than the number of bytes "read" in text mode.
806

Sun Oct  4 00:50:47 1998  Felix Lee  
808

830
Tue May 12 12:10:33 PDT 1998  James Ingham  
831
 
832
        * Makefile.in: The run target depended on a target psim$(EXEEXT),
833
        but there was no such target, only plain psim.  So I changed the
834
        run target to depend on psim.

        * aclocal.m4:  Remove defs of AM_EXEEXT and AM_CYGWIN32.  These are
839
        now defined in ../common/aclocal.m4, and the double definition causes
840
        problems with AC_SUBST of EXEEXT.
841
        * configure:  Regenerate.

1111
 
1112
        * Many of the ppc-opcode-* files are identical baring the type of
1113
        lookup table.  Instead of having multiple tables, igen can do this
1114
        via an additional option.
1115
 
1116
        * ld-decode.h, ld-decode.c (force_decode_gen_type): New function,

1120
        * ld-decode.c (load_decode_table): Allow the table type to be
1121
        overridden.
1122
 
1123
        * igen.c (main): Add -T  option so that an overriding
1124
        instruction decode mechanism can be specified.
1125
 
1126
        * configure.in: New option --sim-decode-mechanism to control
1127
        igen's new -T  flag.

1142
 
1143
        * Makefile.in (callback.o): Define HAVE_CONFIG_H, so callback.c

1156
Wed Feb  5 10:56:27 1997  Andrew Cagney  
1157
 
1158
        * Property create/initialization still wasn't correctly ordered.
1159
        Should be delaying everything related to ihandle creation until
1160
        after the rest of the tree has been established.
1161
 
1162
        * device.c (device_find_ihandle_runtime_property): Update.
1163
        (device_add_ihandle_runtime_property): Update.
1164
 
1165

1179
        works for normal and boolean table entries.

1181
        * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
1182

1183
        it.
1184
 
1185
Mon Feb  3 17:18:16 1997  Andrew Cagney  
1186

1193
        count.

        (psim_max_iterations_exceeded): New function, abort simulation if
1196
        max iterations exceeded.
1197
 
1198
        * gen-idecode.c: Re-work the table lookup code so that it assumes
1199
        that the entry is a leaf by default.  Simplify the boolean table
1200
        entry code so that it involves a mask + test instead of shift +
1201
        shift + mask + test.
1202
 
1203
        * gen-idecode.c: Correct generated igen body so that it no drops
1204
        or doubles clock interrupts.
1205
 
1206
 
1207
Thu Jan 30 11:23:20 1997  Andrew Cagney  
1208

1224
        (gentmap,targ-vals.def): Build from common directory.
1225
        (targ-vals.h,targ-map.c): Build by running gentmap.
1226
        (callback.o): Build from source in common directory.
1227
        (targ-map.o): Add dependency.
1228
        (clean): Remove gentmap.
1229
 
1230
Wed Jan 29 12:14:19 1997  Andrew Cagney  
1231
 
1232
        * igen wasn't aborting if the opcode table contained no valid
1233
        fields.
1234
 
1235
        * misc.c (name2i): Possibly abort if an invalid name is
1236
        encountered.
1237
        * ld-decode.c: Abort if the table type isn't found.
1238
 
1239
Wed Jan 29 12:14:19 1997  Andrew Cagney  
1240
 
1241
        * When performance monitoring is disabled, it is still possible to
1242
        determine the simulation speed by looking at the number of elapsed
1243
        ticks recorded by the event queue.
1244
 
1245
        * psim.c (psim_write_register, psim_read_register): Force the cpu
1246
        to zero when it is either of `-1' or `nr_cpus'.  In both cases the
1247
        next cpu would be zero any way.
1248
 
1249
        * mon.c (mon_print_info): If possible, print the system cycle
1250
        performance.  This is an indication of the number of instructions
1251
        per second.
1252
 
1253
Wed Jan 29 12:14:19 1997  Andrew Cagney  
1254
 
1255
        * The code to allow an event queue to be updated during a signal
1256
        was missing.  For main.c, a cntrl-c simulation termination wasn't
1257
        handled cleanly.
1258
 
1259
        * The simulation would not correctly restart if an event requested
1260
        that the simulation be halted.
1261
 
1262
        * psim.c (psim_options): Add hack to -i option to optionally
1263
        include a level vis -i2.

        (psim_usage): Document.
1265
 
1266
        * main.c (cntrl_c, cntrl_c_simulation): New functions.  When a
1267
        cntrl-c occures schedule an event to halt the simulation.
1268
        (main): Catch CNTRL-C signals with the function cntrl_c.
1269
 
1270
        * events.c (event_queue_process): Mask interrupts while
1271
        manipulating the async event queue.
1272
        (event_queue_init): Ditto.
1273
        (event_queue_schedule_after_signal): Ditto.
1274
 
1275
        * events.c (event_queue_process): Mark the event queue as being in
1276
        the processing state when processing has started.  Adjust code
1277
        so that it is tolerant of halts.
1278
        (event_queue_init): Start the event queue out with processing
1279
        false.
1280
        (event_queue_tick): Check that processing isn't still being
1281
        performed.
1282
 
1283
        * gen-idecode.c (print_run_until_stop_body): Call
1284
        event_queue_process_events to clear possibly pending events before
1285
        starting a simulation run.  Re-arange main loop so that simulator
1286
        is correctly restarted when an event halts the simulation.
1287
 
1288
        * psim.c (psim_halt): Handle an event halting the simulation.
1289
        * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1290
        reworked idecode.
1291
 
1292
Wed Jan 29 12:14:19 1997  Andrew Cagney  
1293
 
1294
        * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1295
        RA.  Based on instruction frequency stats, expand additional
1296
        instructions.
1297
        * ppc-instructions: Change all `RA == 0' to RA_is_0.
1298
 
1299
        * ppc-opcode-stupid: Move all but the basic table in -complex into
1300
        here.  Update to new format.
1301
 
1302
        * Makefile.in (tmp-defines): New target. Force defines.h to always
1303
        be built.  Hence get ppc-opcode-goto to build.
1304
 
1305
Tue Jan 28 13:00:19 1997  Andrew Cagney  
1306
 
1307
        * hw_com.c (hw_com_instance_read, hw_com_instance_write):
1308
        Implement.
1309
 
1310
Thu Jan 23 09:07:26 1997  Andrew Cagney  
1311
 
1312
        * hw_trace.c (hw_trace_init_data): Delete.  The trace options need
1313
        to be initialized independant of the rest of the simulation
1314
        initalization.  Otherwize a trace option explictly set from gdb
1315
        could be overridden by hw_trace.
1316
 
1317
        * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1318
 
1319
        * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1320
        debug.c.  It could be much simpler.
1321
 
1322
Thu Jan 23 09:07:26 1997  Andrew Cagney  
1323
 
1324
        * Some devices support removable media.  Add hooks to the disk
1325
        device so that it supports this.
1326
 
1327
        * device.c (device_add_string_array_property,
1328
        device_find_string_array_property): New functions, manipulate
1329
        properties containing an array of strings.

        (device_init_static_properties): Update.
1332
        (device_init_runtime_properties): Update.
1333
 
1334
        * hw_disk.c (hw_disk_ioctl): Add ioctl for changing the disk
1335
        media.  If no file image is specified, use the next one in the
1336
        image property list.
1337
        (hw_disk_init_address): Change the file property so that it is a
1338
        string array - use the first entry for the initial file image.
1339
 
1340
        * tree.c (print_string_aray_property): New function - print a
1341
        string array.
1342
        (print_properties): Adjust.
1343
        (print_string): Write a string, handling double quotes.
1344
 
1345
        * device.h: Define an ioctl to `change-media' with an optional new
1346
        media image.
1347
 
1348
        * hw_disk.c: Allow floppy disk devices to be specified.
1349
 
1350
        * psim.c (psim_command): New function, parse more complex psim
1351
        commands such as "change-media" and "trace".
1352
        * sim_calls.c (sim_do_command): Use.
1353
 
1354
Wed Jan 22 09:38:33 1997  Andrew Cagney  
1355
 
1356
        * For expressions like (RA == 0) that are entered in to the cache
1357
        as RA_is_0. If possible generate the result of the expression so
1358
        that the compiler gets a better chance of eliminating dead
1359
        branches.
1360
 
1361
        * gen-icache.c (print_icache_extraction): For a cache entry of
1362
        the form _is_ where it is a boolean field, generate
1363
        the result of the expression instead of the expression its self.
1364
        (print_icache_body): Remove code that was looking for *_is_0 and
1365
        then generating corresponding definitions.
1366
 
1367
        * gen-icache.c (print_icache_struct): If there is no cache, do not
1368
        output expressions in idecode.h file.
1369
 
1370
        * gen-icache.c (print_icache_body): Output them here.
1371
 
1372
        * ppc-opcode-complex: Clarify constant values for SPR==LR register
1373
        expansion.
1374
 
1375
        * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
1376
 
1377
Wed Jan 22 12:24:52 1997  Andrew Cagney  
1378
 
1379
        * The code that put values in and extracted values from the cache
1380
        was too compilicated.  The cache table did not allow values to be
1381
        computed from cache entries.  #defines could only be used when a
1382
        cache was present, remove the restriction.
1383
 
1384
        * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH.  A
1385
        scratch variable is defined when a cache entry is beinf
1386
        filled. Change the definition of a COMPUTE variable to be defined
1387
        when the cache entry is being used.
1388
        * gen-icache.c: Update.
1389
 
1390
        * ld-cache.h, ld-cache.c: Change field names so that their meaning
1391
        is more obvious.  old_name->field_name, new_name->derived_name.
1392
        * gen-icache.c: Update
1393
 
1394
        * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1395
        different types of cache code - put into cache, extract from
1396
        cache, no cache - an explicit argument to print_icache_body.
1397
        * gen-icache.c (print_icache_extraction): Ditto.
1398
 
1399

2799
 
2800
        * emul_generic.c (emul_add_tree_options): Was incorrectly setting

2812
 
2813

2814
        instead of just the code to handle a single instruction issue.
2815
        * : Have the generated idecode.c include inline.c (instead of psim.c).
2816
 
2817
        * std-config.h: Change psim.c so that it isn't inlined (as this is
2818
        no longer needed).
2819
 
2820
        * psim.c (run_until_stop): Delete the old run_until_stop function
2821
        instead calling the idecode_run and idecode_run_until_stop
2822
        functions that gen-idecode.c is now creating.
2823
 
2824
Sun Jul 21 21:18:05 1996  Andrew Cagney  
2825

        current instructions name and source line number.
2844
 
2845
        * gen-semantics.c, gen-icache.c: Adjust generated ITRACE calls to

2852
        of ITRACE.  The CPP line directives would have previously set the

2856
 
2857
        * gen-idecode.c (print_jump_until_stop_body): New function and
2858
        idecode generation option.  Instead of generating and calling
2859
        separate functions containing the semantic and icache code

2869
        is being create.
2870
 
2871
        * ppc-opcode-jump: New file.  Set of opcode rules useful when

2882
        * configure.in (--enable-sim-icache): Accept an option list such
2883
        as 1024,define.  Add a new choice to the list - semantic - which

2885
        include the corresponding semantic code.
2886

2890
        Enable/disable the inclusion of CPP line directives in the
2891
        generated files.  Such directives refer back to the source files
2892
        used when generating the simulator code.
2893
 
2894
        * Makefile.in (sim_line_nr): Pass to igen.

2905
        * Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so
2906

3808
 
3809
        * debug.h: Add trace_print_info, trace_print_device_tree and
3810
        trace_dump_device_tree.  The first is a replacement for the
3811
        variable `print_info' found in main.c and sim_calls.c.  The latter
3812
        two enable the dumping of the entire device tree.
3813
 
3814
        * debug.c: Add to trace_description table.
3815
 
3816
        * main.c (main): Use above trace instead of local variable
3817
        * sim_calls.c (sim_close): Ditto
3818
 
3819
        * device.c (device_tree_print_device): New.  Prints the device
3820
        tree in a format that is consistent with what can be parsed by the
3821
        device tree load from file code.
3822
 
3823
        * psim.c (psim_create): Dump device tree if enabled. If nump
3824
        selected, exit psim immediatly.
3825

3827
 
3828
        * corefile-n.h (core_map_read_N): When mapping from an address to
3829
        a device, do not subtract the devices base.  The device its self
3830
        can do this.  Brings the behavour into line with OpenBoot.
3831
        * corefile-n.h (core_map_write_N): Ditto
3832
        * corefile.c (core_map_read_buffer): Ditto

3835
        * device_table.c (console_io_read_buffer_callback): Adjust to
3836
        handle biased address.
3837
        * device_table.c (console_io_write_buffer_callback): Ditto
3838
 
3839
Wed Jan 17 18:36:09 1996  Andrew Cagney  
3840
 
3841
        * device.c (attach_device_interrupt_edge): New. Interrupt model
3842
        did not allow interrupts to be wired up as a general net (edges).
3843
        Re-implement so that interrupt events can be passed to multiple
3844
        controllers and interrupt controllers can further propogate
3845
        interrupt events.
3846
 
3847
        * device.c (attach_device_interrupt_edge) : New, Ditto

3858
        * device.c (device_interrupt) : Delete old
3859
        * device.c (device_interrupt_ack) : Delete old
3860
 
3861
        * device_table.c (unimp_*) : Update to match
3862
 
3863
        * device_table.c (icu_io_write_buffer_callback) : Update to use
3864
        interface.
3865
        * device_table.c (icu_interrupt_event_callback) : Ditto
3866
 
3867
Wed Jan 17 18:18:40 1996  Andrew Cagney  
3868
 
3869
        * device.c (external_to_device) : New function that provides a
3870
        standard mapping between a devices internal representation (a
3871
        pointer) and its external (or what is passed to a client)
3872
        representation (a phandle).  Implement using the cap object
3873
        attached to the root node.
3874
 
3875
        * device.c (device_to_external) : Ditto
3876
        * device.c (external_to_device_instance) : Ditto but for ihandle
3877
        and device instance.
3878
        * device.c (device_instance_to_external) : Ditto
3879
 
3880
        * Makefile (device.o): Add dependency on cap.
3881
 
3882
        * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3883
        needing to translate between internal and external representations
3884
        changed to use the external_to_device et.al. device operations.
3885
        * emul_chirp.c (chirp_emul_*) : Ditto
3886
 
3887
        * Makefile (emul_chirp.o): Remove dependency on cap

3892
        on OpenBoot note section.
3893
 
3894
Fri Jan  5 20:28:53 1996  Andrew Cagney  
3895
 
3896
        * emul_generic.c (emul_write_buffer): Use vm faulting byte
3897
        read/write calls for buffer transfers.  This will cause a fault to
3898
        occure if the transfer fails.  CHRP catches the fault while the
3899
        others suffer the consequences.
3900
        (emul_read_buffer): Ditto.
3901
        (emul_write_word): Ditto.

3908
        emul_generic (emul_blr_instruction): Use a real blr instruction to
3909
        return from a client service call.
3910
 
3911
        * emul_chirp.c (services): Add all OpenBoot services to table.
3912
 
3913
        * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
3914
