980 when it is empty.
981 * emul_chirp.c (map_over_chirp_note): Default load-base to -1 not
982 CHIRP_LOAD_BASE.

1010
1011 * sim-endian.h: Don't have parameters on macro definitions which
1012 are simply renaming functions, to permit use of XCONCAT2 in both
1013 the macro name and the arguments in a use of such a definition.
1014
1015 2000-11-15 Jim Blandy <jimb@redhat.com>
1016
1017 * sim_calls.c: Doc fix.

1031
1032 * events.c (event_queue_process): Call update_time_from_event
1033 every time an event is removed from the queue.
1034 (update_time_from_event): Delete assertion that a negative
1035 time_from_event implies an empty event queue.
1036
1037 Fri Apr 28 15:53:54 2000 Andrew Cagney <cagney@b1.cygnus.com>
1038
1039 * interrupts.c (deliver_hardware_interrupt): Print time trace in

1052
1053 1999-05-08 Felix Lee <flee@cygnus.com>
1054
1055 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
1056 * configure: Regenerated to track ../common/aclocal.m4 changes.
1057
1058 1999-04-02 Keith Seitz <keiths@cygnus.com>
1059
1060 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
1061 the frequency at which the poll_quit callback is called.
1062 (poll_quit_count): New global.
1063 (sim_io_poll_quit): Only call the poll_quit callback
1064 after the specified POLL_QUIT_INTERVAL.
1065
1066 1999-02-22 Jim Lemke <jlemke@cygnus.com>
1067
1068 * dc-complex: Force expansion on all bits of field BO.
1069 Previously, the least-significant (prediction) bit was ignored.
1070 * ppc-instructions (conditional branches): Implement mpc860c0 option.
1071 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
1072 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.
1073 * interrupts.h: Added "mpc860c0_instruction_program_interrupt".
1074 * interrupts.c (program_interrupt): Added handling for above interrupt.
1075
1076 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
1077
1078 Make the simulator compatible with the MPC750. It would be nicer
1079 to make this a real multi-sim, but that's more work than we have
1080 time for.
1081 * emul_generic.c (emul_add_tree_options): Only require strict
1082 alignment if it was explicitly requested at configuration time.
1083 Don't make it the default for little-endian machines.
1084 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
1085 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1086 THRM2, THRM3): Plop in the MPC750 SPR registers.
1087 (DABR): This is weird. This was HID5, but the PPC spec says this
1088 should be DABR; why did some random processor use it for something
1089 else? The HID5 entry dates back to the original checkin of the
1090 simulator code in 1995, so remove it.
1091 * sim_calls.c (register_names): Delete this; since the user can
1092 now change GDB's list of register names dynamically, we can't
1093 pretend there's a static mapping here.
1094 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1095 function to get the register name. That ought to be accurate.
1096 However, we're changing a compile-time dependency (using the
1097 REGISTER_NAMES macro) into a link- and run-time dependency
1098 (calling REGISTER_NAME, which happens to be a function call on the
1099 PPC).
1100
1101 1999-01-22 Jim Lemke <jlemke@cygnus.com>
1102
1103 * igen.c(gen_semantics_[ch]): setup/use of new option
1104 (-o mpc860c0[=n]).
1105 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
1106 ppc-instructions(the four branch insn groups): detect problematic br's.
1107 psim.c(is_num - added, psim_options): Parse and init new option.
1108 These changes are currently under #ifdef WITH_OPTION_MPC860C0.

1117
1118 * events.c (SIM_EVENTS_POLL_RATE): Define.
1119 (sim_events_poll): Copy function from common/sim-events.c.
1120 (event_queue_init): Copy scheduling of sim_events_poll from same.
1121
1122 * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
1123 poll the external environment.
1124
1125 1998-11-19 Michael Meissner <meissner@cygnus.com>
1126
1127 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
1128 fractional type, so that quiet NaN's aren't treated like
1129 Infinities.
1130
1131 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1132
1133 * table.c (table_open): For cygwin hosts, we need to use the
1134 return value from the read routine as the number of bytes to
1135 process. This apparently is due to text-mode vs binary-mode. If
1136 the mounts are done text-mode, then the size returnedby fstat()
1137 may be different than the number of bytes "read" in text mode.
1138
1139 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
1140
1141 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

1155 1998-06-26 Michael Meissner <meissner@cygnus.com>
1156
1157 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
1158 * configure: Regenerate.
1159 * emul_{netbsd,unix}.c (toplevel): No longer try to include
1160 sys/mount.h. It conflicts on Linux when gnu libc2 is used.

1162 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1163
1164 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1165 but there was no such target, only plain psim. So I changed the
1166 run target to depend on psim.
1167
1168 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1169
1170 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are

1443
1444 * Many of the ppc-opcode-* files are identical baring the type of
1445 lookup table. Instead of having multiple tables, igen can do this
1446 via an additional option.
1447

1473 * sim_calls.c (sim_{ctrl_c,resume}): Ditto.
1474
1475 * Makefile.in (callback.o): Define HAVE_CONFIG_H, so callback.c
1476 includes our config.h.
1477
1478 Tue Feb 4 13:42:59 1997 Doug Evans <dje@canuck.cygnus.com>
1479
1480 * configure.in: Fix typo in test for callback.c.

1502
1503 * gen-icache.c (print_icache_extraction): Add a reason parameter.
1504 Augment each extracted field with a comment citing the codes
1505 origin. Should simplify tracking down incorrect cache
1506 extractions.
1507
1508 Tue Feb 4 17:44:51 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1509
1510 * gen-icache.c: Generalize code handling XXX_is_NNN so that it
1511 works for normal and boolean table entries.
1512
1513 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
1514 valid. Handle this just like *_{read,write}_register now handles

1528 max iterations exceeded.
1529
1530 * gen-idecode.c: Re-work the table lookup code so that it assumes
1531 that the entry is a leaf by default. Simplify the boolean table
1532 entry code so that it involves a mask + test instead of shift +
1533 shift + mask + test.
1534
1535 * gen-idecode.c: Correct generated igen body so that it no drops
1536 or doubles clock interrupts.
1537
1538
1539 Thu Jan 30 11:23:20 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1563
1564 * igen wasn't aborting if the opcode table contained no valid
1565 fields.
1566
1567 * misc.c (name2i): Possibly abort if an invalid name is
1568 encountered.
1569 * ld-decode.c: Abort if the table type isn't found.
1570
1571 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1572
1573 * When performance monitoring is disabled, it is still possible to
1574 determine the simulation speed by looking at the number of elapsed
1575 ticks recorded by the event queue.
1576
1577 * psim.c (psim_write_register, psim_read_register): Force the cpu
1578 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1579 next cpu would be zero any way.
1580
1581 * mon.c (mon_print_info): If possible, print the system cycle
1582 performance. This is an indication of the number of instructions
1583 per second.
1584
1585 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1586
1587 * The code to allow an event queue to be updated during a signal
1588 was missing. For main.c, a cntrl-c simulation termination wasn't
1589 handled cleanly.
1590
1591 * The simulation would not correctly restart if an event requested
1592 that the simulation be halted.
1593
1594 * psim.c (psim_options): Add hack to -i option to optionally
1595 include a level vis -i2.
1596 (psim_usage): Document.
1597
1598 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a
1599 cntrl-c occures schedule an event to halt the simulation.
1600 (main): Catch CNTRL-C signals with the function cntrl_c.
1601
1602 * events.c (event_queue_process): Mask interrupts while
1603 manipulating the async event queue.
1604 (event_queue_init): Ditto.
1605 (event_queue_schedule_after_signal): Ditto.
1606
1607 * events.c (event_queue_process): Mark the event queue as being in
1608 the processing state when processing has started. Adjust code
1609 so that it is tolerant of halts.
1610 (event_queue_init): Start the event queue out with processing
1611 false.
1612 (event_queue_tick): Check that processing isn't still being
1613 performed.
1614
1615 * gen-idecode.c (print_run_until_stop_body): Call
1616 event_queue_process_events to clear possibly pending events before
1617 starting a simulation run. Re-arange main loop so that simulator
1618 is correctly restarted when an event halts the simulation.
1619
1620 * psim.c (psim_halt): Handle an event halting the simulation.
1621 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1622 reworked idecode.
1623
1624 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1625
1626 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1627 RA. Based on instruction frequency stats, expand additional
1628 instructions.
1629 * ppc-instructions: Change all `RA == 0' to RA_is_0.
1630
1631 * ppc-opcode-stupid: Move all but the basic table in -complex into
1632 here. Update to new format.
1633
1634 * Makefile.in (tmp-defines): New target. Force defines.h to always
1635 be built. Hence get ppc-opcode-goto to build.
1636
1637 Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1638
1639 * hw_com.c (hw_com_instance_read, hw_com_instance_write):
1640 Implement.
1641
1642 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1643
1644 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1645 to be initialized independant of the rest of the simulation
1646 initalization. Otherwize a trace option explictly set from gdb
1647 could be overridden by hw_trace.
1648
1649 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1650
1651 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1652 debug.c. It could be much simpler.
1653
1654 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1655
1656 * Some devices support removable media. Add hooks to the disk
1657 device so that it supports this.
1658
1659 * device.c (device_add_string_array_property,
1660 device_find_string_array_property): New functions, manipulate
1661 properties containing an array of strings.

1664 (device_init_runtime_properties): Update.
1665
1666 * hw_disk.c (hw_disk_ioctl): Add ioctl for changing the disk
1667 media. If no file image is specified, use the next one in the
1668 image property list.
1669 (hw_disk_init_address): Change the file property so that it is a
1670 string array - use the first entry for the initial file image.
1671
1672 * tree.c (print_string_aray_property): New function - print a
1673 string array.
1674 (print_properties): Adjust.
1675 (print_string): Write a string, handling double quotes.
1676
1677 * device.h: Define an ioctl to `change-media' with an optional new
1678 media image.
1679
1680 * hw_disk.c: Allow floppy disk devices to be specified.
1681
1682 * psim.c (psim_command): New function, parse more complex psim
1683 commands such as "change-media" and "trace".
1684 * sim_calls.c (sim_do_command): Use.
1685
1686 Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1687
1688 * For expressions like (RA == 0) that are entered in to the cache
1689 as RA_is_0. If possible generate the result of the expression so
1690 that the compiler gets a better chance of eliminating dead
1691 branches.
1692
1693 * gen-icache.c (print_icache_extraction): For a cache entry of
1694 the form <name>_is_<const> where it is a boolean field, generate
1695 the result of the expression instead of the expression its self.
1696 (print_icache_body): Remove code that was looking for *_is_0 and
1697 then generating corresponding definitions.
1698
1699 * gen-icache.c (print_icache_struct): If there is no cache, do not
1700 output expressions in idecode.h file.
1701
1702 * gen-icache.c (print_icache_body): Output them here.
1703
1704 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1705 expansion.
1706
1707 * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
1708
1709 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1710
1711 * The code that put values in and extracted values from the cache
1712 was too compilicated. The cache table did not allow values to be
1713 computed from cache entries. #defines could only be used when a
1714 cache was present, remove the restriction.
1715
1716 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1717 scratch variable is defined when a cache entry is beinf
1718 filled. Change the definition of a COMPUTE variable to be defined
1719 when the cache entry is being used.
1720 * gen-icache.c: Update.
1721
1722 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1723 is more obvious. old_name->field_name, new_name->derived_name.
1724 * gen-icache.c: Update
1725
1726 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1727 different types of cache code - put into cache, extract from
1728 cache, no cache - an explicit argument to print_icache_body.
1729 * gen-icache.c (print_icache_extraction): Ditto.
1730
1731 * gen-semantics.c (print_c_semantic): Update use.
1732 * gen-idecode.c (print_jump_insn): Update use.
1733 * gen-icache.c (print_icache_function): Update use.
1734
1735 * igen.c (main): Change 'R' option so that it does not force the
1736 cache.
1737
1738 * configure.in (enable-sim-icache): Clarify description. Make
1739 #define one of the defaults regardless of the cache. Probably
1740 should revamp and add a separate option.
1741
1742 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1743
1744 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos
1745 partition numbering.
1746 (pk_disklabel_create_instance): Partition 1..4 are valid - not
1747 1..3.
1748 (is_iso9660): New function, verify a CD9660 File system.
1749 (pk_disklabel_create_instance): Start expanding so that active
1750 partition selection is supported.
1751
1752 Mon Jan 20 11:20:15 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1753
1754 * The cap object was retaining a reference to the instance of a
1755 device after it was deleted. Instead add and remove cap's from the
1756 cap db as they are created and deleted. This ensuring that a
1757 capibility is only used during the lifetime of the corresponding
1758 object.
1759
1760 * cap.h, cap.c: Correct cap type - was signed32 should be
1761 signed_cell.
1762
1763 * cap.c (cap_add, cap_remove): New methods for cap object that
1764 allow the explicit addition and removal of internal objects that
1765 the cap knows about.
1766
1767 * cap.c (cap_init): Rewrite. Verify that the only objects
1768 remaining in the cap data base are those that were entered first.
1769 Thse objects will be the permenant ones.
1770 * device.c (device_init_address): Remember to initialize the cap
1771 database.
1772
1773 * device.c (device_create_instance_from): Explicitly add device
1774 instances to the cap database. Simplify create code.
1775 (device_instance_delete): Explicitly remove device instances from
1776 the cap database.

1790
1791 Sun Jan 19 15:28:23 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1792
1793 * The memory "claim" and "release" methods take an address and
1794 size as arguments. These may be multi cell values. Initially fix
1795 the memory code so that they check/detect this. Leave the
1796 adjustment of any clients to later.
1797
1798 * hw_memory.c (hw_memory_instance_claim,
1799 hw_memory_instance_release): Handle multi-cell memory devices.
1800
1801 * hw_memory.c (hw_memory_instance_claim): Be tolerant towards the

1803
1804 Fri Jan 17 12:01:07 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1805
1806 * device.h, device.c (device_instance_call_method): Correct return
1807 type - can return either 0 or -1, hence should be a signed type.
1808 * device_table.h: Ditto.

3220
3221 * configure.in: New option --enable-sim-line-nr (default enabled).
