1019 * events.c (event_queue_process): Call update_time_from_event
1020 every time an event is removed from the queue.
1021 (update_time_from_event): Delete assertion that a negative
1022 time_from_event implies an empty event queue.
1024 Fri Apr 28 15:53:54 2000 Andrew Cagney <cagney@b1.cygnus.com>
1026 * interrupts.c (deliver_hardware_interrupt): Print time trace in
1027 decimal.

1033 * ppc-instructions (Disabled_Exponent_Underflow): Increment
1034 the exponent when denormalizing.
1036 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
1038 * configure: Regenerated to track ../common/aclocal.m4 changes.
1040 1999-05-08 Felix Lee <flee@cygnus.com>
1042 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
1043 * configure: Regenerated to track ../common/aclocal.m4 changes.
1045 1999-04-02 Keith Seitz <keiths@cygnus.com>
1047 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
1048 the frequency at which the poll_quit callback is called.
1049 (poll_quit_count): New global.
1050 (sim_io_poll_quit): Only call the poll_quit callback
1051 after the specified POLL_QUIT_INTERVAL.
1053 1999-02-22 Jim Lemke <jlemke@cygnus.com>
1055 * dc-complex: Force expansion on all bits of field BO.
1056 Previously, the least-significant (prediction) bit was ignored.
1057 * ppc-instructions (conditional branches): Implement mpc860c0 option.
1058 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
1059 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.
1060 * interrupts.h: Added "mpc860c0_instruction_program_interrupt".
1061 * interrupts.c (program_interrupt): Added handling for above interrupt.
1063 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
1065 Make the simulator compatible with the MPC750. It would be nicer
1066 to make this a real multi-sim, but that's more work than we have
1067 time for.
1068 * emul_generic.c (emul_add_tree_options): Only require strict
1069 alignment if it was explicitly requested at configuration time.
1070 Don't make it the default for little-endian machines.
1071 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
1072 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1073 THRM2, THRM3): Plop in the MPC750 SPR registers.
1074 (DABR): This is weird. This was HID5, but the PPC spec says this
1075 should be DABR; why did some random processor use it for something
1076 else? The HID5 entry dates back to the original checkin of the
1077 simulator code in 1995, so remove it.
1078 * sim_calls.c (register_names): Delete this; since the user can
1079 now change GDB's list of register names dynamically, we can't
1080 pretend there's a static mapping here.
1081 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1082 function to get the register name. That ought to be accurate.
1083 However, we're changing a compile-time dependency (using the
1084 REGISTER_NAMES macro) into a link- and run-time dependency
1085 (calling REGISTER_NAME, which happens to be a function call on the
1086 PPC).
1088 1999-01-22 Jim Lemke <jlemke@cygnus.com>
1090 * igen.c(gen_semantics_[ch]): setup/use of new option
1091 (-o mpc860c0[=n]).

1093 ppc-instructions(the four branch insn groups): detect problematic br's.
1094 psim.c(is_num - added, psim_options): Parse and init new option.
1095 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
1097 1998-12-01 Ken Raeburn <raeburn@cygnus.com>
1099 * hw_nvram.c (hw_nvram_bcd): Force value to fit in 0..99.

1107 (event_queue_init): Copy scheduling of sim_events_poll from same.
1109 * sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
1110 poll the external environment.
1112 1998-11-19 Michael Meissner <meissner@cygnus.com>
1114 * ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
1115 fractional type, so that quiet NaN's aren't treated like
1116 Infinities.
1118 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
1120 * table.c (table_open): For cygwin hosts, we need to use the
1121 return value from the read routine as the number of bytes to
1122 process. This apparently is due to text-mode vs binary-mode. If
1123 the mounts are done text-mode, then the size returnedby fstat()
1124 may be different than the number of bytes "read" in text mode.
1126 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
1128 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

1140 return zero when nothing to do.
1142 1998-06-26 Michael Meissner <meissner@cygnus.com>
1144 * configure.in (AC_CHECK_HEADERS): Don't check for sys/mount.h.
1145 * configure: Regenerate.
1146 * emul_{netbsd,unix}.c (toplevel): No longer try to include
1147 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
1149 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
1151 * Makefile.in: The run target depended on a target psim$(EXEEXT),
1152 but there was no such target, only plain psim. So I changed the
1153 run target to depend on psim.
1155 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
1157 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
1158 now defined in ../common/aclocal.m4, and the double definition causes
1159 problems with AC_SUBST of EXEEXT.
1160 * configure: Regenerate.
1162 Wed Apr 29 15:44:52 1998 Geoffrey Noer <noer@cygnus.com>

1242 (sim_io_flush_stdoutput): Replace gdb_flush with callback ->
1243 flush_stdout.
1245 Fri Sep 26 09:50:29 1997 Andrew Cagney <cagney@b1.cygnus.com>
1247 * ppc-instructions (sraw, slw, srw): From Charles Lefurgy, Fix

1491 Augment each extracted field with a comment citing the codes
1492 origin. Should simplify tracking down incorrect cache
1493 extractions.

1497 * gen-icache.c: Generalize code handling XXX_is_NNN so that it
1498 works for normal and boolean table entries.

1513 (psim_usage): Document.
1514 (psim_max_iterations_exceeded): New function, abort simulation if
1515 max iterations exceeded.
1517 * gen-idecode.c: Re-work the table lookup code so that it assumes
1518 that the entry is a leaf by default. Simplify the boolean table
1519 entry code so that it involves a mask + test instead of shift +
1520 shift + mask + test.
1522 * gen-idecode.c: Correct generated igen body so that it no drops
1523 or doubles clock interrupts.
1526 Thu Jan 30 11:23:20 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1528 * Makefile.in (BUILT_SRC_WO_CONFIG): Change targ-vals.* to
1529 @sim_targ_vals@

1534 Wed Jan 29 12:32:41 1997 Michael Meissner <meissner@tiktok.cygnus.com>
1536 * configure.in (sim_callback): If the gdb is post 4.16, configure
1537 callback support from the common directory.
1538 * configure: Regenerate.
1540 * Makefile.in (BUILT_SRC_WO_CONFIG): Add targ-vals.{h,def} and
1541 targ-map.c.
1542 (GDB_OBJ): Add callback support configured in.

1546 (targ-map.o): Add dependency.
1547 (clean): Remove gentmap.
1549 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1555 encountered.
1556 * ld-decode.c: Abort if the table type isn't found.
1558 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1560 * When performance monitoring is disabled, it is still possible to
1561 determine the simulation speed by looking at the number of elapsed
1562 ticks recorded by the event queue.
1564 * psim.c (psim_write_register, psim_read_register): Force the cpu
1565 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1566 next cpu would be zero any way.
1568 * mon.c (mon_print_info): If possible, print the system cycle
1569 performance. This is an indication of the number of instructions
1570 per second.
1572 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1574 * The code to allow an event queue to be updated during a signal
1575 was missing. For main.c, a cntrl-c simulation termination wasn't
1576 handled cleanly.
1578 * The simulation would not correctly restart if an event requested
1579 that the simulation be halted.
1581 * psim.c (psim_options): Add hack to -i option to optionally
1582 include a level vis -i2.
1583 (psim_usage): Document.
1585 * main.c (cntrl_c, cntrl_c_simulation): New functions. When a
1586 cntrl-c occures schedule an event to halt the simulation.
1587 (main): Catch CNTRL-C signals with the function cntrl_c.
1589 * events.c (event_queue_process): Mask interrupts while
1590 manipulating the async event queue.
1591 (event_queue_init): Ditto.
1592 (event_queue_schedule_after_signal): Ditto.
1594 * events.c (event_queue_process): Mark the event queue as being in
1595 the processing state when processing has started. Adjust code
1596 so that it is tolerant of halts.
1597 (event_queue_init): Start the event queue out with processing
1598 false.
1599 (event_queue_tick): Check that processing isn't still being
1600 performed.
1602 * gen-idecode.c (print_run_until_stop_body): Call
1603 event_queue_process_events to clear possibly pending events before
1604 starting a simulation run. Re-arange main loop so that simulator
1605 is correctly restarted when an event halts the simulation.
1607 * psim.c (psim_halt): Handle an event halting the simulation.
1608 * psim.c (psim_init): Adjust initial cpu - == -1 - to match
1609 reworked idecode.
1611 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1613 * ppc-opcode-complex: Correct typo - was expanding ORA instead of
1614 RA. Based on instruction frequency stats, expand additional
1615 instructions.
1616 * ppc-instructions: Change all `RA == 0' to RA_is_0.
1618 * ppc-opcode-stupid: Move all but the basic table in -complex into
1619 here. Update to new format.
1621 * Makefile.in (tmp-defines): New target. Force defines.h to always
1622 be built. Hence get ppc-opcode-goto to build.
1624 Tue Jan 28 13:00:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1626 * hw_com.c (hw_com_instance_read, hw_com_instance_write):
1627 Implement.
1629 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1631 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1632 to be initialized independant of the rest of the simulation
1633 initalization. Otherwize a trace option explictly set from gdb
1634 could be overridden by hw_trace.
1636 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1638 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1639 debug.c. It could be much simpler.
1641 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1643 * Some devices support removable media. Add hooks to the disk
1644 device so that it supports this.
1646 * device.c (device_add_string_array_property,
1647 device_find_string_array_property): New functions, manipulate
1648 properties containing an array of strings.
1649 (device_find_string_property): Allow a string array.

1651 (device_init_runtime_properties): Update.
1653 * hw_disk.c (hw_disk_ioctl): Add ioctl for changing the disk
1654 media. If no file image is specified, use the next one in the
1655 image property list.
1656 (hw_disk_init_address): Change the file property so that it is a
1657 string array - use the first entry for the initial file image.
1659 * tree.c (print_string_aray_property): New function - print a
1660 string array.
1661 (print_properties): Adjust.
1662 (print_string): Write a string, handling double quotes.
1664 * device.h: Define an ioctl to `change-media' with an optional new
1665 media image.
1667 * hw_disk.c: Allow floppy disk devices to be specified.
1669 * psim.c (psim_command): New function, parse more complex psim
1670 commands such as "change-media" and "trace".
1671 * sim_calls.c (sim_do_command): Use.
1673 Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1675 * For expressions like (RA == 0) that are entered in to the cache
1676 as RA_is_0. If possible generate the result of the expression so
1677 that the compiler gets a better chance of eliminating dead
1678 branches.
1680 * gen-icache.c (print_icache_extraction): For a cache entry of
1681 the form <name>_is_<const> where it is a boolean field, generate
1682 the result of the expression instead of the expression its self.
1683 (print_icache_body): Remove code that was looking for *_is_0 and
1684 then generating corresponding definitions.
1686 * gen-icache.c (print_icache_struct): If there is no cache, do not
1687 output expressions in idecode.h file.
1689 * gen-icache.c (print_icache_body): Output them here.
1691 * ppc-opcode-complex: Clarify constant values for SPR==LR register
1692 expansion.
1694 * ppc-cache-rules (RA_is_0, SPR_is_256): Two new cache entries.
1696 Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1698 * The code that put values in and extracted values from the cache
1699 was too compilicated. The cache table did not allow values to be
1700 computed from cache entries. #defines could only be used when a
1701 cache was present, remove the restriction.
1703 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1704 scratch variable is defined when a cache entry is beinf
1705 filled. Change the definition of a COMPUTE variable to be defined
1706 when the cache entry is being used.
1707 * gen-icache.c: Update.
1709 * ld-cache.h, ld-cache.c: Change field names so that their meaning
1710 is more obvious. old_name->field_name, new_name->derived_name.
1711 * gen-icache.c: Update
1713 * gen-icache.h, gen-icache.c (print_icache_body): Make the three
1714 different types of cache code - put into cache, extract from
1715 cache, no cache - an explicit argument to print_icache_body.
1716 * gen-icache.c (print_icache_extraction): Ditto.
1718 * gen-semantics.c (print_c_semantic): Update use.
1719 * gen-idecode.c (print_jump_insn): Update use.
1720 * gen-icache.c (print_icache_function): Update use.
1722 * igen.c (main): Change 'R' option so that it does not force the
1723 cache.
1725 * configure.in (enable-sim-icache): Clarify description. Make
1726 #define one of the defaults regardless of the cache. Probably
1727 should revamp and add a separate option.
1729 Tue Jan 21 13:26:10 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1731 * pk_disklabel.c (block_is_fdisk): Tidy up traces - use dos

1741 * The cap object was retaining a reference to the instance of a
1742 device after it was deleted. Instead add and remove cap's from the
1743 cap db as they are created and deleted. This ensuring that a
1744 capibility is only used during the lifetime of the corresponding
1745 object.
1747 * cap.h, cap.c: Correct cap type - was signed32 should be
1748 signed_cell.
1750 * cap.c (cap_add, cap_remove): New methods for cap object that
1751 allow the explicit addition and removal of internal objects that
1752 the cap knows about.
1754 * cap.c (cap_init): Rewrite. Verify that the only objects
1755 remaining in the cap data base are those that were entered first.
1756 Thse objects will be the permenant ones.
1757 * device.c (device_init_address): Remember to initialize the cap
1758 database.
1760 * device.c (device_create_instance_from): Explicitly add device
1761 instances to the cap database. Simplify create code.

1780 * The memory "claim" and "release" methods take an address and
1781 size as arguments. These may be multi cell values. Initially fix
1782 the memory code so that they check/detect this. Leave the
1783 adjustment of any clients to later.
1785 * hw_memory.c (hw_memory_instance_claim,
1786 hw_memory_instance_release): Handle multi-cell memory devices.
1788 * hw_memory.c (hw_memory_instance_claim): Be tolerant towards the
1789 release of memory regions that were not claimed.
1791 Fri Jan 17 12:01:07 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1793 * device.h, device.c (device_instance_call_method): Correct return

1805 method belonging to "/chosen/memory".
1806 (chirm_emul_release): Ditto.
1808 * Makefile.in (LIB_INLINE_SRC): Remove emul_* from list of files
1809 that are inlined. These modules are called via a table and are
1810 not made inline.
1812 * hw_init.c (update_for_binary_section): Fix failure to allocate
1813 memory used by the binary in real-mode executions. If "claim"
1814 property is present, allocate memory from the "/chosen/memory"

3039 always update the cache_entries semantic and address fields.
3041 * gen-idecode.c (print_idecode_switch_illegal): Include a break
3042 when generating illegal instructions. This was commented out
3043 which is a hangover from looking a at switch statements generated
3044 using indirect jumps.
3046 Tue Jul 23 20:57:01 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
3048 * igen.c (print_my_defines): Replaces print_define_my_index.

3084 hardware devices that are to be included in the build. Makes it
3085 possible for user packages to be specified.
3087 * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
3088 hardware instead of checking it using ls. configure.in should
3089 have taken care of any problems.
3090 (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure.
3092 Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>
3094 * psim.c (psim_options): Enter the argument to the memory size
3095 option directly into the device tree. Was using atol() which is

3134 * : Have the generated idecode.c include inline.c (instead of psim.c).
3136 * std-config.h: Change psim.c so that it isn't inlined (as this is
3137 no longer needed).
3139 * psim.c (run_until_stop): Delete the old run_until_stop function
3140 instead calling the idecode_run and idecode_run_until_stop
3141 functions that gen-idecode.c is now creating.
3143 Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>

3165 match new interface.
3167 * emul_bugapi.c (emul_bugapi_instruction_call): Adjust
3168 corresponding call to ITRACE so that it still matches.
3170 * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead
3171 of ITRACE. The CPP line directives would have previously set the
3172 line-nr and file name so ITRACE isn't needed.
3174 Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
3176 * gen-idecode.c (print_jump_until_stop_body): New function and
3177 idecode generation option. Instead of generating and calling

3202 as 1024,define. Add a new choice to the list - semantic - which
3203 will cause igen to generate instruction decode functions that
3204 include the corresponding semantic code.
3206 Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
3208 * configure.in: New option --enable-sim-line-nr (default enabled).

3211 used when generating the simulator code.
3213 * Makefile.in (sim_line_nr): Pass to igen.
3215 Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
