908 the frequency at which the poll_quit callback is called.
909 (poll_quit_count): New global.
910 (sim_io_poll_quit): Only call the poll_quit callback
911 after the specified POLL_QUIT_INTERVAL.
912

925 Make the simulator compatible with the MPC750. It would be nicer
926 to make this a real multi-sim, but that's more work than we have
927 time for.
928 * emul_generic.c (emul_add_tree_options): Only require strict
929 alignment if it was explicitly requested at configuration time.
930 Don't make it the default for little-endian machines.
931 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
932 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
933 THRM2, THRM3): Plop in the MPC750 SPR registers.
934 (DABR): This is weird. This was HID5, but the PPC spec says this
935 should be DABR; why did some random processor use it for something
936 else? The HID5 entry dates back to the original checkin of the
937 simulator code in 1995, so remove it.
938 * sim_calls.c (register_names): Delete this; since the user can
939 now change GDB's list of register names dynamically, we can't
940 pretend there's a static mapping here.
941 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
942 function to get the register name. That ought to be accurate.
943 However, we're changing a compile-time dependency (using the
944 REGISTER_NAMES macro) into a link- and run-time dependency
945 (calling REGISTER_NAME, which happens to be a function call on the
946 PPC).
947
9481999-01-22 Jim Lemke <jlemke@cygnus.com>
949
950 * igen.c(gen_semantics_[ch]): setup/use of new option

954 psim.c(is_num - added, psim_options): Parse and init new option.
955 These changes are currently under #ifdef WITH_OPTION_MPC860C0.

976 Infinities.
977
978Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
979
980 * table.c (table_open): For cygwin hosts, we need to use the
981 return value from the read routine as the number of bytes to
982 process. This apparently is due to text-mode vs binary-mode. If
983 the mounts are done text-mode, then the size returnedby fstat()
984 may be different than the number of bytes "read" in text mode.

1011 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1012 but there was no such target, only plain psim. So I changed the
1013 run target to depend on psim.
1014
1015Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1016
1017 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are

1290
1291 * Many of the ppc-opcode-* files are identical baring the type of

1320 * sim_calls.c (sim_{ctrl_c,resume}): Ditto.
1321
1322 * Makefile.in (callback.o): Define HAVE_CONFIG_H, so callback.c
1323 includes our config.h.
1324
1325Tue Feb 4 13:42:59 1997 Doug Evans <dje@canuck.cygnus.com>
1326
1327 * configure.in: Fix typo in test for callback.c.

1348Wed Feb 5 10:56:27 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1349
1350 * gen-icache.c (print_icache_extraction): Add a reason parameter.
1351 Augment each extracted field with a comment citing the codes
1352 origin. Should simplify tracking down incorrect cache
1353 extractions.
1354
1355Tue Feb 4 17:44:51 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1356
1357 * gen-icache.c: Generalize code handling XXX_is_NNN so that it
1358 works for normal and boolean table entries.
1359
1360 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
1361 valid. Handle this just like *_{read,write}_register now handles

1376
1377 * gen-idecode.c: Re-work the table lookup code so that it assumes
1378 that the entry is a leaf by default. Simplify the boolean table
1379 entry code so that it involves a mask + test instead of shift +
1380 shift + mask + test.
1381
1382 * gen-idecode.c: Correct generated igen body so that it no drops
1383 or doubles clock interrupts.
1384
1385
1386Thu Jan 30 11:23:20 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1410
1411 * igen wasn't aborting if the opcode table contained no valid
1412 fields.
1413
1414 * misc.c (name2i): Possibly abort if an invalid name is
1415 encountered.
1416 * ld-decode.c: Abort if the table type isn't found.

1418Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1419
1420 * When performance monitoring is disabled, it is still possible to
1421 determine the simulation speed by looking at the number of elapsed
1422 ticks recorded by the event queue.
1423
1424 * psim.c (psim_write_register, psim_read_register): Force the cpu
1425 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1426 next cpu would be zero any way.
1427
1428 * mon.c (mon_print_info): If possible, print the system cycle
1429 performance. This is an indication of the number of instructions
1430 per second.
1431
1432Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1433
1434 * The code to allow an event queue to be updated during a signal
1435 was missing. For main.c, a cntrl-c simulation termination wasn't
1436 handled cleanly.
1437
1438 * The simulation would not correctly restart if an event requested
1439 that the simulation be halted.
1440
1441 * psim.c (psim_options): Add hack to -i option to optionally
1442 include a level vis -i2.
1443 (psim_usage): Document.
1444
1445 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a
1446 cntrl-c occures schedule an event to halt the simulation.
1447 (main): Catch CNTRL-C signals with the function cntrl_c.
1448
1449 * events.c (event_queue_process): Mask interrupts while
1450 manipulating the async event queue.

1452 (event_queue_schedule_after_signal): Ditto.
1453
1454 * events.c (event_queue_process): Mark the event queue as being in
1455 the processing state when processing has started. Adjust code
1456 so that it is tolerant of halts.
1457 (event_queue_init): Start the event queue out with processing
1458 false.
1459 (event_queue_tick): Check that processing isn't still being
1460 performed.
1461
1462 * gen-idecode.c (print_run_until_stop_body): Call
1463 event_queue_process_events to clear possibly pending events before
1464 starting a simulation run. Re-arange main loop so that simulator
1465 is correctly restarted when an event halts the simulation.

1467 * psim.c (psim_halt): Handle an event halting the simulation.
1468 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1469 reworked idecode.
1470
1471Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1472
1473 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1474 RA. Based on instruction frequency stats, expand additional
1475 instructions.
1476 * ppc-instructions: Change all `RA == 0' to RA_is_0.
1477
1478 * ppc-opcode-stupid: Move all but the basic table in -complex into
1479 here. Update to new format.
1480
1481 * Makefile.in (tmp-defines): New target. Force defines.h to always
1482 be built. Hence get ppc-opcode-goto to build.
1483
1484Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1485
1486 * hw_com.c (hw_com_instance_read, hw_com_instance_write):
1487 Implement.
1488
1489Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1490
1491 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1492 to be initialized independant of the rest of the simulation
1493 initalization. Otherwize a trace option explictly set from gdb
1494 could be overridden by hw_trace.
1495
1496 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1497
1498 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1499 debug.c. It could be much simpler.
1500
1501Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1502
1503 * Some devices support removable media. Add hooks to the disk
1504 device so that it supports this.

1514 media. If no file image is specified, use the next one in the
1515 image property list.
1516 (hw_disk_init_address): Change the file property so that it is a
1517 string array - use the first entry for the initial file image.
1518
1519 * tree.c (print_string_aray_property): New function - print a
1520 string array.
1521 (print_properties): Adjust.
1522 (print_string): Write a string, handling double quotes.
1523

1528
1529 * psim.c (psim_command): New function, parse more complex psim
1530 commands such as "change-media" and "trace".

1532
1533Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1534
1535 * For expressions like (RA == 0) that are entered in to the cache
1536 as RA_is_0. If possible generate the result of the expression so
1537 that the compiler gets a better chance of eliminating dead
1538 branches.
1539
1540 * gen-icache.c (print_icache_extraction): For a cache entry of
1541 the form <name>_is_<const> where it is a boolean field, generate
1542 the result of the expression instead of the expression its self.
1543 (print_icache_body): Remove code that was looking for *_is_0 and
1544 then generating corresponding definitions.
1545
1546 * gen-icache.c (print_icache_struct): If there is no cache, do not
1547 output expressions in idecode.h file.
1548
1549 * gen-icache.c (print_icache_body): Output them here.
1550
1551 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1552 expansion.

1556Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1557
1558 * The code that put values in and extracted values from the cache
1559 was too compilicated. The cache table did not allow values to be
1560 computed from cache entries. #defines could only be used when a
1561 cache was present, remove the restriction.
1562
1563 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1564 scratch variable is defined when a cache entry is beinf
1565 filled. Change the definition of a COMPUTE variable to be defined
1566 when the cache entry is being used.
1567 * gen-icache.c: Update.
1568
1569 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1570 is more obvious. old_name->field_name, new_name->derived_name.
1571 * gen-icache.c: Update
1572
1573 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1574 different types of cache code - put into cache, extract from
1575 cache, no cache - an explicit argument to print_icache_body.
1576 * gen-icache.c (print_icache_extraction): Ditto.
1577
1578 * gen-semantics.c (print_c_semantic): Update use.
1579 * gen-idecode.c (print_jump_insn): Update use.
1580 * gen-icache.c (print_icache_function): Update use.
1581
1582 * igen.c (main): Change 'R' option so that it does not force the
1583 cache.
1584
1585 * configure.in (enable-sim-icache): Clarify description. Make
1586 #define one of the defaults regardless of the cache. Probably
1587 should revamp and add a separate option.
1588
1589Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1590

1599Mon Jan 20 11:20:15 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1600
1601 * The cap object was retaining a reference to the instance of a
1602 device after it was deleted. Instead add and remove cap's from the
1603 cap db as they are created and deleted. This ensuring that a
1604 capibility is only used during the lifetime of the corresponding
1605 object.
1606
1607 * cap.h, cap.c: Correct cap type - was signed32 should be
1608 signed_cell.
1609
1610 * cap.c (cap_add, cap_remove): New methods for cap object that
1611 allow the explicit addition and removal of internal objects that
1612 the cap knows about.
1613
1614 * cap.c (cap_init): Rewrite. Verify that the only objects
1615 remaining in the cap data base are those that were entered first.
1616 Thse objects will be the permenant ones.
1617 * device.c (device_init_address): Remember to initialize the cap
1618 database.
1619
1620 * device.c (device_create_instance_from): Explicitly add device

1639
1640 * The memory "claim" and "release" methods take an address and
1641 size as arguments. These may be multi cell values. Initially fix
1642 the memory code so that they check/detect this. Leave the
1643 adjustment of any clients to later.
1644
1645 * hw_memory.c (hw_memory_instance_claim,
1646 hw_memory_instance_release): Handle multi-cell memory devices.

1652
1653 * device.h, device.c (device_instance_call_method): Correct return
1654 type - can return either 0 or -1, hence should be a signed type.

1670 not made inline.
1671
1672 * hw_init.c (update_for_binary_section): Fix failure to allocate
1673 memory used by the binary in real-mode executions. If "claim"

1675 device.
1676
1677 * emul_chirp.c (emul_chirp_create): Specify that memory should be
1678 claimed when loading a real image.

2899 always update the cache_entries semantic and address fields.
2900
2901 * gen-idecode.c (print_idecode_switch_illegal): Include a break

2916 modules that include it.
2917 * inline.h, inline.c: Adjust so that support.[hc] is handled the
2918 same as cpu.[hc].
2919
2920 * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
2921 name for a lable and then branch to it.
2922
2923 * ppc-instructions (convert_to_integer, Floating Round to
2924 Single-Precision, Floating Convert from Integer Doubleword): Use
2925 LABEL and GOTO instead of the recently added switch statements.

2951
2952Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>

2995
2996 * std-config.h: Change psim.c so that it isn't inlined (as this is
2997 no longer needed).
2998
2999 * psim.c (run_until_stop): Delete the old run_until_stop function
3000 instead calling the idecode_run and idecode_run_until_stop
3001 functions that gen-idecode.c is now creating.

3035
3036 * gen-idecode.c (print_jump_until_stop_body): New function and
3037 idecode generation option. Instead of generating and calling

3051 testing jumping idecodes.
3052

3067
3068 * configure.in: New option --enable-sim-line-nr (default enabled).

3971 * device.c (device_usage): New. Output help including a list of
3972 the devices currently available in the device table.
3973 * device_table.c: Add usage operator to each device.
3974
3975 * corefile.c (core_create, core_device_create): Adjust so that the
3976 core device is created earlier for psim_tree(). Core can later be
3977 created from it.
3978
3979 * psim.c (psim_create): Update to handle above way of creating
3980 things. Extract all information from the device tree.
3981
3982 * device_tree.c (trace_*): New device node, its properties are
3983 used to set the value of the trace options. Init this device (in
3984 psim_options) when ever the options are updated.
3985
3986Wed Jan 17 19:46:07 1996 Andrew Cagney <cagney@highland.com.au>
3987
3988 * debug.h: Add trace_print_info, trace_print_device_tree and
3989 trace_dump_device_tree. The first is a replacement for the
3990 variable `print_info' found in main.c and sim_calls.c. The latter
3991 two enable the dumping of the entire device tree.
3992
3993 * debug.c: Add to trace_description table.
3994
3995 * main.c (main): Use above trace instead of local variable
3996 * sim_calls.c (sim_close): Ditto
3997
3998 * device.c (device_tree_print_device): New. Prints the device
3999 tree in a format that is consistent with what can be parsed by the
4000 device tree load from file code.
4001
4002 * psim.c (psim_create): Dump device tree if enabled. If nump
576054f1 4003 selected, exit psim immediately.

4006
4007 * corefile-n.h (core_map_read_N): When mapping from an address to
4008 a device, do not subtract the devices base. The device its self
4009 can do this. Brings the behavour into line with OpenBoot.
4010 * corefile-n.h (core_map_write_N): Ditto
4011 * corefile.c (core_map_read_buffer): Ditto
4012 * corefile.c (core_map_write_buffer): Ditto
4013
4014 * device_table.c (console_io_read_buffer_callback): Adjust to
4015 handle biased address.
4016 * device_table.c (console_io_write_buffer_callback): Ditto
4017

4019
4020 * device.c (attach_device_interrupt_edge): New. Interrupt model
4021 did not allow interrupts to be wired up as a general net (edges).
4022 Re-implement so that interrupt events can be passed to multiple
4023 controllers and interrupt controllers can further propogate
4024 interrupt events.
4025
4026 * device.c (attach_device_interrupt_edge) : New, Ditto
4027 * device.c (detach_device_interrupt_edge) : New, Ditto
4028 * device.c (clean_device_interrupt_edges) : New, Ditto
4029 * device.c (device_interrupt_event) : New, Ditto

4046Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
4047
4048 * device.c (external_to_device) : New function that provides a
4049 standard mapping between a devices internal representation (a
4050 pointer) and its external (or what is passed to a client)
4051 representation (a phandle). Implement using the cap object
4052 attached to the root node.
4053
4054 * device.c (device_to_external) : Ditto
4055 * device.c (external_to_device_instance) : Ditto but for ihandle
4056 and device instance.
4057 * device.c (device_instance_to_external) : Ditto
4058
4059 * Makefile (device.o): Add dependency on cap.
4060
4061 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
4062 needing to translate between internal and external representations
4063 changed to use the external_to_device et.al. device operations.
4064 * emul_chirp.c (chirp_emul_*) : Ditto
4065
4066 * Makefile (emul_chirp.o): Remove dependency on cap

4074
4075 * emul_generic.c (emul_write_buffer): Use vm faulting byte
4076 read/write calls for buffer transfers. This will cause a fault to
4077 occure if the transfer fails. CHRP catches the fault while the
4078 others suffer the consequences.
4079 (emul_read_buffer): Ditto.
4080 (emul_write_word): Ditto.
4081 (emul_read_word): Ditto.
