1017 (update_time_from_event): Delete assertion that a negative
1018 time_from_event implies an empty event queue.
1020 Fri Apr 28 15:53:54 2000 Andrew Cagney <cagney@b1.cygnus.com>

1029 * ppc-instructions (Disabled_Exponent_Underflow): Increment
1030 the exponent when denormalizing.
1032 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
1034 * configure: Regenerated to track ../common/aclocal.m4 changes.
1036 1999-05-08 Felix Lee <flee@cygnus.com>
1038 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
1039 * configure: Regenerated to track ../common/aclocal.m4 changes.
1041 1999-04-02 Keith Seitz <keiths@cygnus.com>
1043 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
1044 the frequency at which the poll_quit callback is called.
1045 (poll_quit_count): New global.
1046 (sim_io_poll_quit): Only call the poll_quit callback
1047 after the specified POLL_QUIT_INTERVAL.
1049 1999-02-22 Jim Lemke <jlemke@cygnus.com>
1051 * dc-complex: Force expansion on all bits of field BO.
1052 Previously, the least-significant (prediction) bit was ignored.
1053 * ppc-instructions (conditional branches): Implement mpc860c0 option.
1054 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
1055 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.
1056 * interrupts.h: Added "mpc860c0_instruction_program_interrupt".
1057 * interrupts.c (program_interrupt): Added handling for above interrupt.
1059 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
1061 Make the simulator compatible with the MPC750. It would be nicer
1062 to make this a real multi-sim, but that's more work than we have
1063 time for.
1064 * emul_generic.c (emul_add_tree_options): Only require strict
1065 alignment if it was explicitly requested at configuration time.
1066 Don't make it the default for little-endian machines.
1067 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
1068 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1069 THRM2, THRM3): Plop in the MPC750 SPR registers.
1070 (DABR): This is weird. This was HID5, but the PPC spec says this
1071 should be DABR; why did some random processor use it for something
1072 else? The HID5 entry dates back to the original checkin of the
1073 simulator code in 1995, so remove it.
1074 * sim_calls.c (register_names): Delete this; since the user can
1075 now change GDB's list of register names dynamically, we can't
1076 pretend there's a static mapping here.
1077 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1078 function to get the register name. That ought to be accurate.
1079 However, we're changing a compile-time dependency (using the
1080 REGISTER_NAMES macro) into a link- and run-time dependency
1081 (calling REGISTER_NAME, which happens to be a function call on the
1082 PPC).
1084 1999-01-22 Jim Lemke <jlemke@cygnus.com>
1086 * igen.c(gen_semantics_[ch]): setup/use of new option
1087 (-o mpc860c0[=n]).
1088 interrupts.[ch](mpc860c0_instruction_program_interrupt): added.
1089 ppc-instructions(the four branch insn groups): detect problematic br's.
1090 psim.c(is_num - added, psim_options): Parse and init new option.
1091 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
1093 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
1095 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

1103 (event_queue_init): Copy scheduling of sim_events_poll from same.
1105 * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
1106 poll the external environment.
1108 1998-11-19 Michael Meissner <meissner@cygnus.com>
1110 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
1111 fractional type, so that quiet NaN's aren't treated like
1112 Infinities.
1114 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1116 * table.c (table_open): For cygwin hosts, we need to use the
1117 return value from the read routine as the number of bytes to
1118 process. This apparently is due to text-mode vs binary-mode. If
1119 the mounts are done text-mode, then the size returnedby fstat()
1120 may be different than the number of bytes "read" in text mode.
1122 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
1124 * emul_netbsd.c (do_open): fix order-of-evaluation problem.
1125 (do_close): ditto.

1136 return zero when nothing to do.
1138 1998-06-26 Michael Meissner <meissner@cygnus.com>
1140 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
1141 * configure: Regenerate.
1142 * emul_{netbsd,unix}.c (toplevel): No longer try to include
1143 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
1145 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1147 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1148 but there was no such target, only plain psim. So I changed the
1149 run target to depend on psim.
1151 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1153 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
1154 now defined in ../common/aclocal.m4, and the double definition causes
1155 problems with AC_SUBST of EXEEXT.
1156 * configure: Regenerate.
1158 Wed Apr 29 15:44:52 1998 Geoffrey Noer <noer@cygnus.com>

1238 (sim_io_flush_stdoutput): Replace gdb_flush with callback ->
1239 flush_stdout.
1241 Fri Sep 26 09:50:29 1997 Andrew Cagney <cagney@b1.cygnus.com>

1487 Augment each extracted field with a comment citing the codes
1488 origin. Should simplify tracking down incorrect cache

1509 (psim_usage): Document.
1510 (psim_max_iterations_exceeded): New function, abort simulation if
1511 max iterations exceeded.
1513 * gen-idecode.c: Re-work the table lookup code so that it assumes
1514 that the entry is a leaf by default. Simplify the boolean table
1515 entry code so that it involves a mask + test instead of shift +
1516 shift + mask + test.
1518 * gen-idecode.c: Correct generated igen body so that it no drops
1519 or doubles clock interrupts.
1522 Thu Jan 30 11:23:20 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1524 * Makefile.in (BUILT_SRC_WO_CONFIG): Change targ-vals.* to
1525 @sim_targ_vals@

1530 Wed Jan 29 12:32:41 1997 Michael Meissner <meissner@tiktok.cygnus.com>
1532 * configure.in (sim_callback): If the gdb is post 4.16, configure
1533 callback support from the common directory.
1534 * configure: Regenerate.
1536 * Makefile.in (BUILT_SRC_WO_CONFIG): Add targ-vals.{h,def} and
1537 targ-map.c.
1538 (GDB_OBJ): Add callback support configured in.

1543 (clean): Remove gentmap.
1545 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1548 fields.
1550 * misc.c (name2i): Possibly abort if an invalid name is
1551 encountered.
1552 * ld-decode.c: Abort if the table type isn't found.
1554 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1556 * When performance monitoring is disabled, it is still possible to
1557 determine the simulation speed by looking at the number of elapsed
1558 ticks recorded by the event queue.
1560 * psim.c (psim_write_register, psim_read_register): Force the cpu
1561 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1562 next cpu would be zero any way.
1564 * mon.c (mon_print_info): If possible, print the system cycle
1565 performance. This is an indication of the number of instructions
1566 per second.
1568 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1570 * The code to allow an event queue to be updated during a signal
1571 was missing. For main.c, a cntrl-c simulation termination wasn't
1572 handled cleanly.
1574 * The simulation would not correctly restart if an event requested
1575 that the simulation be halted.
1577 * psim.c (psim_options): Add hack to -i option to optionally
1578 include a level vis -i2.
1579 (psim_usage): Document.
1581 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a
1582 cntrl-c occures schedule an event to halt the simulation.
1583 (main): Catch CNTRL-C signals with the function cntrl_c.
1585 * events.c (event_queue_process): Mask interrupts while
1586 manipulating the async event queue.
1587 (event_queue_init): Ditto.
1588 (event_queue_schedule_after_signal): Ditto.
1590 * events.c (event_queue_process): Mark the event queue as being in
1591 the processing state when processing has started. Adjust code
1592 so that it is tolerant of halts.
1593 (event_queue_init): Start the event queue out with processing
1594 false.
1595 (event_queue_tick): Check that processing isn't still being
1596 performed.
1598 * gen-idecode.c (print_run_until_stop_body): Call
1599 event_queue_process_events to clear possibly pending events before
1600 starting a simulation run. Re-arange main loop so that simulator
1601 is correctly restarted when an event halts the simulation.
1603 * psim.c (psim_halt): Handle an event halting the simulation.
1604 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1605 reworked idecode.
1607 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1609 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1610 RA. Based on instruction frequency stats, expand additional
1611 instructions.
1612 * ppc-instructions: Change all `RA == 0' to RA_is_0.
1614 * ppc-opcode-stupid: Move all but the basic table in -complex into
1615 here. Update to new format.
1617 * Makefile.in (tmp-defines): New target. Force defines.h to always
1618 be built. Hence get ppc-opcode-goto to build.
1620 Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1622 * hw_com.c (hw_com_instance_read, hw_com_instance_write):
1623 Implement.
1625 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1627 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1628 to be initialized independant of the rest of the simulation
1629 initalization. Otherwize a trace option explictly set from gdb
1630 could be overridden by hw_trace.
1632 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1634 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1635 debug.c. It could be much simpler.
1637 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1639 * Some devices support removable media. Add hooks to the disk
1640 device so that it supports this.
1642 * device.c (device_add_string_array_property,
1643 device_find_string_array_property): New functions, manipulate
1644 properties containing an array of strings.
1645 (device_find_string_property): Allow a string array.

1647 (device_init_runtime_properties): Update.
1649 * hw_disk.c (hw_disk_ioctl): Add ioctl for changing the disk
1650 media. If no file image is specified, use the next one in the
1651 image property list.
1652 (hw_disk_init_address): Change the file property so that it is a
1653 string array - use the first entry for the initial file image.
1655 * tree.c (print_string_aray_property): New function - print a
1656 string array.
1657 (print_properties): Adjust.
1658 (print_string): Write a string, handling double quotes.
1660 * device.h: Define an ioctl to `change-media' with an optional new
1661 media image.
1663 * hw_disk.c: Allow floppy disk devices to be specified.
1665 * psim.c (psim_command): New function, parse more complex psim
1666 commands such as "change-media" and "trace".
1667 * sim_calls.c (sim_do_command): Use.
1669 Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1671 * For expressions like (RA == 0) that are entered in to the cache
1672 as RA_is_0. If possible generate the result of the expression so
1673 that the compiler gets a better chance of eliminating dead
1674 branches.
1676 * gen-icache.c (print_icache_extraction): For a cache entry of
1677 the form <name>_is_<const> where it is a boolean field, generate
1678 the result of the expression instead of the expression its self.
1679 (print_icache_body): Remove code that was looking for *_is_0 and
1680 then generating corresponding definitions.
1682 * gen-icache.c (print_icache_struct): If there is no cache, do not
1683 output expressions in idecode.h file.
1685 * gen-icache.c (print_icache_body): Output them here.
1687 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1688 expansion.
1690 * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
1692 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1694 * The code that put values in and extracted values from the cache
1695 was too compilicated. The cache table did not allow values to be
1696 computed from cache entries. #defines could only be used when a
1697 cache was present, remove the restriction.
1699 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1700 scratch variable is defined when a cache entry is beinf
1701 filled. Change the definition of a COMPUTE variable to be defined
1702 when the cache entry is being used.
1703 * gen-icache.c: Update.
1705 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1706 is more obvious. old_name->field_name, new_name->derived_name.
1707 * gen-icache.c: Update
1709 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1710 different types of cache code - put into cache, extract from

1712 * gen-icache.c (print_icache_extraction): Ditto.
1714 * gen-semantics.c (print_c_semantic): Update use.
1715 * gen-idecode.c (print_jump_insn): Update use.
1716 * gen-icache.c (print_icache_function): Update use.
1718 * igen.c (main): Change 'R' option so that it does not force the
1719 cache.
1721 * configure.in (enable-sim-icache): Clarify description. Make
1722 #define one of the defaults regardless of the cache. Probably
1723 should revamp and add a separate option.
1725 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1727 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

1737 * The cap object was retaining a reference to the instance of a
1738 device after it was deleted. Instead add and remove cap's from the
1739 cap db as they are created and deleted. This ensuring that a
1740 capibility is only used during the lifetime of the corresponding
1741 object.
1743 * cap.h, cap.c: Correct cap type - was signed32 should be
1744 signed_cell.
1746 * cap.c (cap_add, cap_remove): New methods for cap object that
1747 allow the explicit addition and removal of internal objects that
1748 the cap knows about.
1750 * cap.c (cap_init): Rewrite. Verify that the only objects
1751 remaining in the cap data base are those that were entered first.
1752 Thse objects will be the permenant ones.
1753 * device.c (device_init_address): Remember to initialize the cap
1754 database.
1756 * device.c (device_create_instance_from): Explicitly add device
1757 instances to the cap database. Simplify create code.

1776 * The memory "claim" and "release" methods take an address and
1777 size as arguments. These may be multi cell values. Initially fix
1778 the memory code so that they check/detect this. Leave the
1779 adjustment of any clients to later.
1781 * hw_memory.c (hw_memory_instance_claim,
1782 hw_memory_instance_release): Handle multi-cell memory devices.
1784 * hw_memory.c (hw_memory_instance_claim): Be tolerant towards the

1800 * emul_chirp.c (chirp_emul_claim): Implement using the "claim"
1801 method belonging to "/chosen/memory".
1802 (chirm_emul_release): Ditto.
1804 * Makefile.in (LIB_INLINE_SRC): Remove emul_* from list of files
1805 that are inlined. These modules are called via a table and are
1806 not made inline.
1808 * hw_init.c (update_for_binary_section): Fix failure to allocate
1809 memory used by the binary in real-mode executions. If "claim"
1810 property is present, allocate memory from the "/chosen/memory"

3035 always update the cache_entries semantic and address fields.
3037 * gen-idecode.c (print_idecode_switch_illegal): Include a break
3038 when generating illegal instructions. This was commented out
3039 which is a hangover from looking a at switch statements generated
3040 using indirect jumps.
3042 Tue Jul 23 20:57:01 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
3044 * igen.c (print_my_defines): Replaces print_define_my_index.

3080 hardware devices that are to be included in the build. Makes it
3081 possible for user packages to be specified.
3083 * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
3084 hardware instead of checking it using ls. configure.in should
3085 have taken care of any problems.
3086 (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure.
3088 Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>
3090 * psim.c (psim_options): Enter the argument to the memory size
3091 option directly into the device tree. Was using atol() which is

3130 * : Have the generated idecode.c include inline.c (instead of psim.c).
3132 * std-config.h: Change psim.c so that it isn't inlined (as this is
3133 no longer needed).
3135 * psim.c (run_until_stop): Delete the old run_until_stop function
3136 instead calling the idecode_run and idecode_run_until_stop
3137 functions that gen-idecode.c is now creating.
3139 Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>

3161 match new interface.
3163 * emul_bugapi.c (emul_bugapi_instruction_call): Adjust
3164 corresponding call to ITRACE so that it still matches.
3166 * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead
3167 of ITRACE. The CPP line directives would have previously set the
3168 line-nr and file name so ITRACE isn't needed.
3170 Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
3172 * gen-idecode.c (print_jump_until_stop_body): New function and
3173 idecode generation option. Instead of generating and calling

3198 as 1024,define. Add a new choice to the list - semantic - which
3199 will cause igen to generate instruction decode functions that
3200 include the corresponding semantic code.
3202 Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
3204 * configure.in: New option --enable-sim-line-nr (default enabled).

3207 used when generating the simulator code.
3209 * Makefile.in (sim_line_nr): Pass to igen.
3211 Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
