929 * dc-complex: Force expansion on all bits of field BO.
930 Previously, the least-significant (prediction) bit was ignored.
931 * ppc-instructions (conditional branches): Implement mpc860c0 option.
932 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
933 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.
934 * interrupts.h: Added "mpc860c0_instruction_program_interrupt".
935 * interrupts.c (program_interrupt): Added handling for above interrupt.
936
937 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
938
939 Make the simulator compatible with the MPC750. It would be nicer
940 to make this a real multi-sim, but that's more work than we have
941 time for.
942 * emul_generic.c (emul_add_tree_options): Only require strict
943 alignment if it was explicitly requested at configuration time.
944 Don't make it the default for little-endian machines.
945 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
946 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
947 THRM2, THRM3): Plop in the MPC750 SPR registers.
948 (DABR): This is weird. This was HID5, but the PPC spec says this
949 should be DABR; why did some random processor use it for something
950 else? The HID5 entry dates back to the original checkin of the
951 simulator code in 1995, so remove it.
952 * sim_calls.c (register_names): Delete this; since the user can
953 now change GDB's list of register names dynamically, we can't
954 pretend there's a static mapping here.
955 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
956 function to get the register name. That ought to be accurate.
957 However, we're changing a compile-time dependency (using the
958 REGISTER_NAMES macro) into a link- and run-time dependency
959 (calling REGISTER_NAME, which happens to be a function call on the
960 PPC).
961
962 1999-01-22 Jim Lemke <jlemke@cygnus.com>
963
964 * igen.c(gen_semantics_[ch]): setup/use of new option
965 (-o mpc860c0[=n]).
966 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
967 ppc-instructions(the four branch insn groups): detect problematic br's.
968 psim.c(is_num - added, psim_options): Parse and init new option.
969 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
970
971 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
972
973 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.
974

982
983 * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
984 poll the external environment.
985
986 1998-11-19 Michael Meissner <meissner@cygnus.com>
987
988 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
989 fractional type, so that quiet NaN's aren't treated like
990 Infinities.
991
992 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
993
994 * table.c (table_open): For cygwin hosts, we need to use the
995 return value from the read routine as the number of bytes to
996 process. This apparently is due to text-mode vs binary-mode. If
997 the mounts are done text-mode, then the size returnedby fstat()
998 may be different than the number of bytes "read" in text mode.
999
1000 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
1001
1002 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

1023 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1024
1025 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1026 but there was no such target, only plain psim. So I changed the
1027 run target to depend on psim.
1028
1029 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1030
1031 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are

1364 * gen-icache.c (print_icache_extraction): Add a reason parameter.
1365 Augment each extracted field with a comment citing the codes
1366 origin. Should simplify tracking down incorrect cache
1367 extractions.
1368
1369 Tue Feb 4 17:44:51 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1370
1371 * gen-icache.c: Generalize code handling XXX_is_NNN so that it
1372 works for normal and boolean table entries.
1373
1374 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
1375 valid. Handle this just like *_{read,write}_register now handles
1376 it.
1377
1378 Mon Feb 3 17:18:16 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1379
1380 * events.c (insert_event_entry): Correct loop termination

1388 (psim_max_iterations_exceeded): New function, abort simulation if
1389 max iterations exceeded.
1390
1391 * gen-idecode.c: Re-work the table lookup code so that it assumes
1392 that the entry is a leaf by default. Simplify the boolean table
1393 entry code so that it involves a mask + test instead of shift +
1394 shift + mask + test.
1395
1396 * gen-idecode.c: Correct generated igen body so that it no drops
1397 or doubles clock interrupts.
1398
1399
1400 Thu Jan 30 11:23:20 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1401
1402 * Makefile.in (BUILT_SRC_WO_CONFIG): Change targ-vals.* to
1403 @sim_targ_vals@
1404
1405 * configure.in (sim_callback, sim_targ_vals): Set sim_targ_valls
1406 if common callback is present.
1407
1408 Wed Jan 29 12:32:41 1997 Michael Meissner <meissner@tiktok.cygnus.com>
1409
1410 * configure.in (sim_callback): If the gdb is post 4.16, configure
1411 callback support from the common directory.
1412 * configure: Regenerate.
1413

1423 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1424
1425 * igen wasn't aborting if the opcode table contained no valid
1426 fields.
1427
1428 * misc.c (name2i): Possibly abort if an invalid name is
1429 encountered.
1430 * ld-decode.c: Abort if the table type isn't found.
1431
1432 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1433
1434 * When performance monitoring is disabled, it is still possible to
1435 determine the simulation speed by looking at the number of elapsed
1436 ticks recorded by the event queue.
1437
1438 * psim.c (psim_write_register, psim_read_register): Force the cpu
1439 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1440 next cpu would be zero any way.
1441
1442 * mon.c (mon_print_info): If possible, print the system cycle
1443 performance. This is an indication of the number of instructions
1444 per second.
1445
1446 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1447
1448 * The code to allow an event queue to be updated during a signal
1449 was missing. For main.c, a cntrl-c simulation termination wasn't
1450 handled cleanly.
1451
1452 * The simulation would not correctly restart if an event requested
1453 that the simulation be halted.
1454
1455 * psim.c (psim_options): Add hack to -i option to optionally
1456 include a level vis -i2.
1457 (psim_usage): Document.
1458
1459 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a
1460 cntrl-c occures schedule an event to halt the simulation.
1461 (main): Catch CNTRL-C signals with the function cntrl_c.
1462
1463 * events.c (event_queue_process): Mask interrupts while
1464 manipulating the async event queue.
1465 (event_queue_init): Ditto.
1466 (event_queue_schedule_after_signal): Ditto.
1467
1468 * events.c (event_queue_process): Mark the event queue as being in
1469 the processing state when processing has started. Adjust code
1470 so that it is tolerant of halts.
1471 (event_queue_init): Start the event queue out with processing
1472 false.
1473 (event_queue_tick): Check that processing isn't still being
1474 performed.
1475
1476 * gen-idecode.c (print_run_until_stop_body): Call
1477 event_queue_process_events to clear possibly pending events before
1478 starting a simulation run. Re-arange main loop so that simulator
1479 is correctly restarted when an event halts the simulation.
1480
1481 * psim.c (psim_halt): Handle an event halting the simulation.
1482 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1483 reworked idecode.
1484
1485 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1486
1487 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1488 RA. Based on instruction frequency stats, expand additional
1489 instructions.
1490 * ppc-instructions: Change all `RA == 0' to RA_is_0.
1491
1492 * ppc-opcode-stupid: Move all but the basic table in -complex into
1493 here. Update to new format.
1494
1495 * Makefile.in (tmp-defines): New target. Force defines.h to always
1496 be built. Hence get ppc-opcode-goto to build.
1497
1498 Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1499
1500 * hw_com.c (hw_com_instance_read, hw_com_instance_write):
1501 Implement.
1502
1503 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1504
1505 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1506 to be initialized independant of the rest of the simulation
1507 initalization. Otherwize a trace option explictly set from gdb
1508 could be overridden by hw_trace.
1509
1510 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1511
1512 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1513 debug.c. It could be much simpler.
1514
1515 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1516
1517 * Some devices support removable media. Add hooks to the disk
1518 device so that it supports this.
1519
1520 * device.c (device_add_string_array_property,
1521 device_find_string_array_property): New functions, manipulate
1522 properties containing an array of strings.

1528 media. If no file image is specified, use the next one in the
1529 image property list.
1530 (hw_disk_init_address): Change the file property so that it is a
1531 string array - use the first entry for the initial file image.
1532
1533 * tree.c (print_string_aray_property): New function - print a
1534 string array.
1535 (print_properties): Adjust.
1536 (print_string): Write a string, handling double quotes.
1537
1538 * device.h: Define an ioctl to `change-media' with an optional new
1539 media image.
1540

1542
1543 * psim.c (psim_command): New function, parse more complex psim
1544 commands such as "change-media" and "trace".
1545 * sim_calls.c (sim_do_command): Use.
1546
1547 Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1548
1549 * For expressions like (RA == 0) that are entered in to the cache
1550 as RA_is_0. If possible generate the result of the expression so
1551 that the compiler gets a better chance of eliminating dead
1552 branches.
1553
1554 * gen-icache.c (print_icache_extraction): For a cache entry of
1555 the form <name>_is_<const> where it is a boolean field, generate
1556 the result of the expression instead of the expression its self.
1557 (print_icache_body): Remove code that was looking for *_is_0 and
1558 then generating corresponding definitions.
1559
1560 * gen-icache.c (print_icache_struct): If there is no cache, do not
1561 output expressions in idecode.h file.
1562
1563 * gen-icache.c (print_icache_body): Output them here.
1564
1565 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1566 expansion.

1570 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1571
1572 * The code that put values in and extracted values from the cache
1573 was too compilicated. The cache table did not allow values to be
1574 computed from cache entries. #defines could only be used when a
1575 cache was present, remove the restriction.
1576
1577 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1578 scratch variable is defined when a cache entry is beinf
1579 filled. Change the definition of a COMPUTE variable to be defined
1580 when the cache entry is being used.
1581 * gen-icache.c: Update.
1582
1583 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1584 is more obvious. old_name->field_name, new_name->derived_name.
1585 * gen-icache.c: Update
1586
1587 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1588 different types of cache code - put into cache, extract from
1589 cache, no cache - an explicit argument to print_icache_body.
1590 * gen-icache.c (print_icache_extraction): Ditto.
1591
1592 * gen-semantics.c (print_c_semantic): Update use.
1593 * gen-idecode.c (print_jump_insn): Update use.
1594 * gen-icache.c (print_icache_function): Update use.
1595
1596 * igen.c (main): Change 'R' option so that it does not force the
1597 cache.
1598
1599 * configure.in (enable-sim-icache): Clarify description. Make
1600 #define one of the defaults regardless of the cache. Probably
1601 should revamp and add a separate option.
1602
1603 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1604

1613 Mon Jan 20 11:20:15 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1614
1615 * The cap object was retaining a reference to the instance of a
1616 device after it was deleted. Instead add and remove cap's from the
1617 cap db as they are created and deleted. This ensuring that a
1618 capibility is only used during the lifetime of the corresponding
1619 object.
1620
1621 * cap.h, cap.c: Correct cap type - was signed32 should be
1622 signed_cell.
1623
1624 * cap.c (cap_add, cap_remove): New methods for cap object that
1625 allow the explicit addition and removal of internal objects that
1626 the cap knows about.
1627
1628 * cap.c (cap_init): Rewrite. Verify that the only objects
1629 remaining in the cap data base are those that were entered first.
1630 Thse objects will be the permenant ones.
1631 * device.c (device_init_address): Remember to initialize the cap
1632 database.
1633
1634 * device.c (device_create_instance_from): Explicitly add device
1635 instances to the cap database. Simplify create code.

1653
1654 * The memory "claim" and "release" methods take an address and
1655 size as arguments. These may be multi cell values. Initially fix
1656 the memory code so that they check/detect this. Leave the
1657 adjustment of any clients to later.
1658
1659 * hw_memory.c (hw_memory_instance_claim,
1660 hw_memory_instance_release): Handle multi-cell memory devices.

1666
1667 * device.h, device.c (device_instance_call_method): Correct return
1668 type - can return either 0 or -1, hence should be a signed type.

1684 not made inline.
1685
1686 * hw_init.c (update_for_binary_section): Fix failure to allocate
1687 memory used by the binary in real-mode executions. If "claim"

2913 always update the cache_entries semantic and address fields.
2914

2930 modules that include it.
2931 * inline.h, inline.c: Adjust so that support.[hc] is handled the
2932 same as cpu.[hc].
2933
2934 * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
2935 name for a lable and then branch to it.
2936
2937 * ppc-instructions (convert_to_integer, Floating Round to
2938 Single-Precision, Floating Convert from Integer Doubleword): Use
2939 LABEL and GOTO instead of the recently added switch statements.

2965
2966 Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>
2967
2968 * psim.c (psim_options): Enter the argument to the memory size
2969 option directly into the device tree. Was using atol() which is

3010 * std-config.h: Change psim.c so that it isn't inlined (as this is
3011 no longer needed).
3012
3013 * psim.c (run_until_stop): Delete the old run_until_stop function
3014 instead calling the idecode_run and idecode_run_until_stop
3015 functions that gen-idecode.c is now creating.

3081
3082 * configure.in: New option --enable-sim-line-nr (default enabled).

4061
4062 * device.c (external_to_device) : New function that provides a
4063 standard mapping between a devices internal representation (a
4064 pointer) and its external (or what is passed to a client)
4065 representation (a phandle). Implement using the cap object
4066 attached to the root node.
4067
4068 * device.c (device_to_external) : Ditto
4069 * device.c (external_to_device_instance) : Ditto but for ihandle
4070 and device instance.
4071 * device.c (device_instance_to_external) : Ditto
4072
4073 * Makefile (device.o): Add dependency on cap.
4074
4075 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
4076 needing to translate between internal and external representations
4077 changed to use the external_to_device et.al. device operations.
4078 * emul_chirp.c (chirp_emul_*) : Ditto
4079
4080 * Makefile (emul_chirp.o): Remove dependency on cap

4088
4089 * emul_generic.c (emul_write_buffer): Use vm faulting byte
4090 read/write calls for buffer transfers. This will cause a fault to
4091 occure if the transfer fails. CHRP catches the fault while the
4092 others suffer the consequences.

4101 emul_generic (emul_blr_instruction): Use a real blr instruction to
4102 return from a client service call.
4103
4104 * emul_chirp.c (services): Add all OpenBoot services to table.
4105
4106 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
4107 (emul_chirp_create) : Use names instead of numbers for
4108 instructions being stored in memory.
