707
        time_from_event implies an empty event queue.

1999-04-02  Keith Seitz  
731
 
732
        * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
733
        the frequency at which the poll_quit callback is called.
734
        (poll_quit_count): New global.
735
        (sim_io_poll_quit): Only call the poll_quit callback
736
        after the specified POLL_QUIT_INTERVAL.
737

1999-02-22  Jim Lemke  
739
 
740
        * dc-complex: Force expansion on all bits of field BO.
741
        Previously, the least-significant (prediction) bit was ignored.
742
        * ppc-instructions (conditional branches): Implement mpc860c0 option.
743
        * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.

748
1999-02-01  Jim Blandy  
749
 
750
        Make the simulator compatible with the MPC750.  It would be nicer
751
        to make this a real multi-sim, but that's more work than we have
752
        time for.
753
        * emul_generic.c (emul_add_tree_options): Only require strict
754
        alignment if it was explicitly requested at configuration time.
755
        Don't make it the default for little-endian machines.
756
        * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
757
        MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
758
        THRM2, THRM3): Plop in the MPC750 SPR registers.
759
        (DABR): This is weird.  This was HID5, but the PPC spec says this
760
        should be DABR; why did some random processor use it for something
761
        else?  The HID5 entry dates back to the original checkin of the
762
        simulator code in 1995, so remove it.
763
        * sim_calls.c (register_names): Delete this; since the user can
764
        now change GDB's list of register names dynamically, we can't
765
        pretend there's a static mapping here.
766
        (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
767
        function to get the register name.  That ought to be accurate.
768
        However, we're changing a compile-time dependency (using the
769
        REGISTER_NAMES macro) into a link- and run-time dependency
770
        (calling REGISTER_NAME, which happens to be a function call on the
771
        PPC).
772
 
773
1999-01-22  Jim Lemke

775
        * igen.c(gen_semantics_[ch]): setup/use of new option

        (-o mpc860c0[=n]).

        interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
778
        ppc-instructions(the four branch insn groups): detect problematic br's.
779
        psim.c(is_num - added, psim_options): Parse and init new option.
780
        These changes are currently under #ifdef WITH_OPTION_MPC860C0.

1998-12-01  Ken Raeburn  
783

        (sim_events_poll): Copy function from common/sim-events.c.
792
        (event_queue_init): Copy scheduling of sim_events_poll from same.
793
 
794
        * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
795
        poll the external environment.

797
1998-11-19  Michael Meissner  
798
 
799
        * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
800
        fractional type, so that quiet NaN's aren't treated like
801
        Infinities.
802
 
803
Mon Sep 28 09:42:45 1998  Drew Moseley  
804
 
805
        * table.c (table_open): For cygwin hosts, we need to use the
806
        return value from the read routine as the number of bytes to
807
        process.  This apparently is due to text-mode vs binary-mode.  If
808
        the mounts are done text-mode, then the size returnedby fstat()
809
        may be different than the number of bytes "read" in text mode.

834
Tue May 12 12:10:33 PDT 1998  James Ingham  
835
 
836
        * Makefile.in: The run target depended on a target psim$(EXEEXT),
837
        but there was no such target, only plain psim.  So I changed the
838
        run target to depend on psim.

        * aclocal.m4:  Remove defs of AM_EXEEXT and AM_CYGWIN32.  These are
843
        now defined in ../common/aclocal.m4, and the double definition causes
844
        problems with AC_SUBST of EXEEXT.
845

1115
 
1116
        * Many of the ppc-opcode-* files are identical baring the type of
1117
        lookup table.  Instead of having multiple tables, igen can do this
1118
        via an additional option.
1119
 
1120
        * ld-decode.h, ld-decode.c (force_decode_gen_type): New function,

1125
        overridden.
1126
 
1127
        * igen.c (main): Add -T  option so that an overriding
1128
        instruction decode mechanism can be specified.
1129
 
1130
        * configure.in: New option --sim-decode-mechanism to control
1131
        igen's new -T  flag.

1160
Wed Feb  5 10:56:27 1997  Andrew Cagney  
1161
 
1162
        * Property create/initialization still wasn't correctly ordered.
1163
        Should be delaying everything related to ihandle creation until
1164
        after the rest of the tree has been established.
1165
 
1166
        * device.c (device_find_ihandle_runtime_property): Update.
1167
        (device_add_ihandle_runtime_property): Update.
1168
 
1169

1183
        works for normal and boolean table entries.
1184
 
1185
        * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
1186

1187
        it.
1188

1190

1200
        max iterations exceeded.
1201
 
1202
        * gen-idecode.c: Re-work the table lookup code so that it assumes
1203
        that the entry is a leaf by default.  Simplify the boolean table
1204
        entry code so that it involves a mask + test instead of shift +
1205
        shift + mask + test.
1206
 
1207
        * gen-idecode.c: Correct generated igen body so that it no drops
1208
        or doubles clock interrupts.

1228
        (gentmap,targ-vals.def): Build from common directory.
1229
        (targ-vals.h,targ-map.c): Build by running gentmap.
1230
        (callback.o): Build from source in common directory.
1231

1233
 
1234
Wed Jan 29 12:14:19 1997  Andrew Cagney  
1235
 
1236
        * igen wasn't aborting if the opcode table contained no valid
1237
        fields.
1238
 
1239
        * misc.c (name2i): Possibly abort if an invalid name is
1240
        encountered.
1241
        * ld-decode.c: Abort if the table type isn't found.
1242
 
1243
Wed Jan 29 12:14:19 1997  Andrew Cagney  
1244
 
1245
        * When performance monitoring is disabled, it is still possible to
1246
        determine the simulation speed by looking at the number of elapsed
1247
        ticks recorded by the event queue.
1248
 
1249
        * psim.c (psim_write_register, psim_read_register): Force the cpu
1250
        to zero when it is either of `-1' or `nr_cpus'.  In both cases the
1251
        next cpu would be zero any way.
1252
 
1253
        * mon.c (mon_print_info): If possible, print the system cycle
1254
        performance.  This is an indication of the number of instructions
1255
        per second.
1256
 
1257
Wed Jan 29 12:14:19 1997  Andrew Cagney  
1258
 
1259
        * The code to allow an event queue to be updated during a signal
1260
        was missing.  For main.c, a cntrl-c simulation termination wasn't
1261
        handled cleanly.
1262
 
1263
        * The simulation would not correctly restart if an event requested
1264
        that the simulation be halted.
1265
 
1266
        * psim.c (psim_options): Add hack to -i option to optionally

        (psim_usage): Document.
1269
 
1270
        * main.c (cntrl_c, cntrl_c_simulation): New functions.  When a
1271
        cntrl-c occures schedule an event to halt the simulation.
1272
        (main): Catch CNTRL-C signals with the function cntrl_c.
1273
 
1274
        * events.c (event_queue_process): Mask interrupts while
1275
        manipulating the async event queue.
1276
        (event_queue_init): Ditto.
1277
        (event_queue_schedule_after_signal): Ditto.
1278
 
1279
        * events.c (event_queue_process): Mark the event queue as being in
1280
        the processing state when processing has started.  Adjust code
1281
        so that it is tolerant of halts.
1282
        (event_queue_init): Start the event queue out with processing
1283
        false.
1284
        (event_queue_tick): Check that processing isn't still being
1285
        performed.
1286
 
1287
        * gen-idecode.c (print_run_until_stop_body): Call
1288
        event_queue_process_events to clear possibly pending events before
1289
        starting a simulation run.  Re-arange main loop so that simulator
1290
        is correctly restarted when an event halts the simulation.
1291
 
1292
        * psim.c (psim_halt): Handle an event halting the simulation.
1293
        * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1294
        reworked idecode.
1295
 
1296
Wed Jan 29 12:14:19 1997  Andrew Cagney  
1297
 
1298
        * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1299
        RA.  Based on instruction frequency stats, expand additional
1300
        instructions.
1301
        * ppc-instructions: Change all `RA == 0' to RA_is_0.
1302
 
1303
        * ppc-opcode-stupid: Move all but the basic table in -complex into
1304
        here.  Update to new format.
1305
 
1306
        * Makefile.in (tmp-defines): New target. Force defines.h to always
1307
        be built.  Hence get ppc-opcode-goto to build.
1308
 
1309
Tue Jan 28 13:00:19 1997  Andrew Cagney  
1310
 
1311
        * hw_com.c (hw_com_instance_read, hw_com_instance_write):
1312
        Implement.
1313
 
1314
Thu Jan 23 09:07:26 1997  Andrew Cagney  
1315
 
1316
        * hw_trace.c (hw_trace_init_data): Delete.  The trace options need
1317
        to be initialized independant of the rest of the simulation
1318
        initalization.  Otherwize a trace option explictly set from gdb
1319
        could be overridden by hw_trace.
1320
 
1321
        * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1322
 
1323
        * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1324
        debug.c.  It could be much simpler.
1325
 
1326
Thu Jan 23 09:07:26 1997  Andrew Cagney  
1327
 
1328
        * Some devices support removable media.  Add hooks to the disk
1329
        device so that it supports this.
1330
 
1331
        * device.c (device_add_string_array_property,
1332
        device_find_string_array_property): New functions, manipulate

        (device_init_runtime_properties): Update.
1337
 
1338
        * hw_disk.c (hw_disk_ioctl): Add ioctl for changing the disk
1339
        media.  If no file image is specified, use the next one in the
1340
        image property list.
1341
        (hw_disk_init_address): Change the file property so that it is a
1342
        string array - use the first entry for the initial file image.
1343
 
1344
        * tree.c (print_string_aray_property): New function - print a
1345
        string array.
1346
        (print_properties): Adjust.
1347
        (print_string): Write a string, handling double quotes.
1348
 
1349
        * device.h: Define an ioctl to `change-media' with an optional new
1350
        media image.
1351
 
1352
        * hw_disk.c: Allow floppy disk devices to be specified.
1353
 
1354
        * psim.c (psim_command): New function, parse more complex psim
1355
        commands such as "change-media" and "trace".
1356
        * sim_calls.c (sim_do_command): Use.
1357
 
1358
Wed Jan 22 09:38:33 1997  Andrew Cagney  
1359
 
1360
        * For expressions like (RA == 0) that are entered in to the cache
1361
        as RA_is_0. If possible generate the result of the expression so
1362
        that the compiler gets a better chance of eliminating dead
1363
        branches.
1364
 
1365
        * gen-icache.c (print_icache_extraction): For a cache entry of
1366
        the form _is_ where it is a boolean field, generate
1367
        the result of the expression instead of the expression its self.
1368
        (print_icache_body): Remove code that was looking for *_is_0 and
1369
        then generating corresponding definitions.
1370
 
1371
        * gen-icache.c (print_icache_struct): If there is no cache, do not
1372
        output expressions in idecode.h file.
1373
 
1374
        * gen-icache.c (print_icache_body): Output them here.
1375
 
1376
        * ppc-opcode-complex: Clarify constant values for SPR==LR register
1377
        expansion.
1378
 
1379
        * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
1380
 
1381
Wed Jan 22 12:24:52 1997  Andrew Cagney  
1382
 
1383
        * The code that put values in and extracted values from the cache
1384
        was too compilicated.  The cache table did not allow values to be
1385
        computed from cache entries.  #defines could only be used when a
1386
        cache was present, remove the restriction.
1387
 
1388
        * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH.  A
1389
        scratch variable is defined when a cache entry is beinf
1390
        filled. Change the definition of a COMPUTE variable to be defined
1391
        when the cache entry is being used.
1392
        * gen-icache.c: Update.
1393
 
1394
        * ld-cache.h, ld-cache.c: Change field names so that their meaning
1395
        is more obvious.  old_name->field_name, new_name->derived_name.
1396
        * gen-icache.c: Update
1397
 
1398
        * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1399
        different types of cache code - put into cache, extract from
1400

2779
        * psim.c (psim_options): Enter the argument to the memory size
2780
        option directly into the device tree.  Was using atol() which is

2803
 
2804
        * emul_generic.c (emul_add_tree_options): Was incorrectly setting

2816
 
2817
        * gen-idecode.c: Output the complete run_until_stop function
2818
        instead of just the code to handle a single instruction issue.

2820
 
2821
        * std-config.h: Change psim.c so that it isn't inlined (as this is
2822
        no longer needed).
2823
 
2824
        * psim.c (run_until_stop): Delete the old run_until_stop function
2825
        instead calling the idecode_run and idecode_run_until_stop
2826
        functions that gen-idecode.c is now creating.
2827
 
2828
Sun Jul 21 21:18:05 1996  Andrew Cagney

2836
 
2837
        * debug.c (TRACE, ITRACE, DTRACE): Have GCC instead of CPP
2838

2847
        current instructions name and source line number.
2848
 
2849
        * gen-semantics.c, gen-icache.c: Adjust generated ITRACE calls to

        corresponding call to ITRACE so that it still matches.
2854
 
2855
        * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead
2856
        of ITRACE.  The CPP line directives would have previously set the
2857
        line-nr and file name so ITRACE isn't needed.
2858

Sun Jul 21 21:18:05 1996  Andrew Cagney  
2860
 
2861
        * gen-idecode.c (print_jump_until_stop_body): New function and
2862
        idecode generation option.  Instead of generating and calling
2863
        separate functions containing the semantic and icache code
2864
        generate a single monolythic function and use goto's (and GCC's
2865
        indirect jump) to move between code blocks.

2873
        is being create.
2874
 
2875
        * ppc-opcode-jump: New file.  Set of opcode rules useful when

2886
        * configure.in (--enable-sim-icache): Accept an option list such
2887
        as 1024,define.  Add a new choice to the list - semantic - which

2889
        include the corresponding semantic code.
2890

2892
 
2893

2894
        Enable/disable the inclusion of CPP line directives in the
2895
        generated files.  Such directives refer back to the source files
2896
        used when generating the simulator code.
2897
 
2898
        * Makefile.in (sim_line_nr): Pass to igen.

2909
        * Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so
2910
        that they use the same technique as igen (ie a dummy targets

3807
        * device_tree.c (trace_*): New device node, its properties are
3808
        used to set the value of the trace options.  Init this device (in
3809
        psim_options) when ever the options are updated.

3811
Wed Jan 17 19:46:07 1996  Andrew Cagney  
3812
 
3813
        * debug.h: Add trace_print_info, trace_print_device_tree and
3814
        trace_dump_device_tree.  The first is a replacement for the
3815
        variable `print_info' found in main.c and sim_calls.c.  The latter
3816
        two enable the dumping of the entire device tree.
3817
 
3818
        * debug.c: Add to trace_description table.
3819
 
3820
        * main.c (main): Use above trace instead of local variable
3821
        * sim_calls.c (sim_close): Ditto
3822
 
3823
        * device.c (device_tree_print_device): New.  Prints the device
3824
        tree in a format that is consistent with what can be parsed by the
3825
        device tree load from file code.
3826
 
3827
        * psim.c (psim_create): Dump device tree if enabled. If nump
3828
        selected, exit psim immediatly.
3829

3831
 
3832
        * corefile-n.h (core_map_read_N): When mapping from an address to
3833
        a device, do not subtract the devices base.  The device its self
3834
        can do this.  Brings the behavour into line with OpenBoot.
3835
        * corefile-n.h (core_map_write_N): Ditto
3836
        * corefile.c (core_map_read_buffer): Ditto

3844
 
3845
        * device.c (attach_device_interrupt_edge): New. Interrupt model
3846
        did not allow interrupts to be wired up as a general net (edges).
3847
        Re-implement so that interrupt events can be passed to multiple
3848
        controllers and interrupt controllers can further propogate
3849
        interrupt events.
3850
 
3851

3866
 
3867
        * device_table.c (icu_io_write_buffer_callback) : Update to use
3868
        interface.
3869
        * device_table.c (icu_interrupt_event_callback) : Ditto

3871
Wed Jan 17 18:18:40 1996  Andrew Cagney  
3872
 
3873
        * device.c (external_to_device) : New function that provides a
3874
        standard mapping between a devices internal representation (a
3875
        pointer) and its external (or what is passed to a client)
3876
        representation (a phandle).  Implement using the cap object
3877
        attached to the root node.
3878
 
3879
        * device.c (device_to_external) : Ditto

3881
        and device instance.
3882
        * device.c (device_instance_to_external) : Ditto
3883
 
3884
        * Makefile (device.o): Add dependency on cap.
3885
 
3886
        * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3887
        needing to translate between internal and external representations
3888
        changed to use the external_to_device et.al. device operations.
3889

3899
 
3900
        * emul_generic.c (emul_write_buffer): Use vm faulting byte
3901
        read/write calls for buffer transfers.  This will cause a fault to
3902
        occure if the transfer fails.  CHRP catches the fault while the
3903
        others suffer the consequences.
3904

3912
        emul_generic (emul_blr_instruction): Use a real blr instruction to
3913
        return from a client service call.
3914
 
3915
        * emul_chirp.c (services): Add all OpenBoot services to table.
