567 open syscall to the numbers supported by the host.
569 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
571 * sim-endian.h: Don't have parameters on macro definitions which
572 are simply renaming functions, to permit use of XCONCAT2 in both
573 the macro name and the arguments in a use of such a definition.
575 2000-11-15 Jim Blandy <jimb@redhat.com>
577 * sim_calls.c: Doc fix.
578 (sim_fetch_register, sim_store_register): Call

613 1999-05-08 Felix Lee <flee@cygnus.com>
615 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
616 * configure: Regenerated to track ../common/aclocal.m4 changes.
618 1999-04-02 Keith Seitz <keiths@cygnus.com>
620 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
621 the frequency at which the poll_quit callback is called.
622 (poll_quit_count): New global.

624 after the specified POLL_QUIT_INTERVAL.
626 1999-02-22 Jim Lemke <jlemke@cygnus.com>
628 * dc-complex: Force expansion on all bits of field BO.
629 Previously, the least-significant (prediction) bit was ignored.
630 * ppc-instructions (conditional branches): Implement mpc860c0 option.

636 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
638 Make the simulator compatible with the MPC750. It would be nicer
639 to make this a real multi-sim, but that's more work than we have
641 * emul_generic.c (emul_add_tree_options): Only require strict
642 alignment if it was explicitly requested at configuration time.
643 Don't make it the default for little-endian machines.
644 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
645 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
646 THRM2, THRM3): Plop in the MPC750 SPR registers.
647 (DABR): This is weird. This was HID5, but the PPC spec says this
648 should be DABR; why did some random processor use it for something
649 else? The HID5 entry dates back to the original checkin of the
650 simulator code in 1995, so remove it.
651 * sim_calls.c (register_names): Delete this; since the user can
652 now change GDB's list of register names dynamically, we can't
653 pretend there's a static mapping here.
654 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
655 function to get the register name. That ought to be accurate.
656 However, we're changing a compile-time dependency (using the
657 REGISTER_NAMES macro) into a link- and run-time dependency
658 (calling REGISTER_NAME, which happens to be a function call on the

688 fractional type, so that quiet NaN's aren't treated like
691 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
693 * table.c (table_open): For cygwin hosts, we need to use the
694 return value from the read routine as the number of bytes to
695 process. This apparently is due to text-mode vs binary-mode. If
696 the mounts are done text-mode, then the size returnedby fstat()
697 may be different than the number of bytes "read" in text mode.
699 Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>
701 * emul_netbsd.c (do_open): fix order-of-evaluation problem.

718 * configure: Regenerate.
719 * emul_{netbsd,unix}.c (toplevel): No longer try to include
720 sys/mount.h. It conflicts on Linux when gnu libc2 is used.
722 Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.cygnus.com>
724 * Makefile.in: The run target depended on a target psim$(EXEEXT),
725 but there was no such target, only plain psim. So I changed the
726 run target to depend on psim.
728 Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
730 * aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are
731 now defined in ../common/aclocal.m4, and the double definition causes

1134 determine the simulation speed by looking at the number of elapsed
1135 ticks recorded by the event queue.
1137 * psim.c (psim_write_register, psim_read_register): Force the cpu
1138 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1139 next cpu would be zero any way.
1141 * mon.c (mon_print_info): If possible, print the system cycle
1142 performance. This is an indication of the number of instructions
1145 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1147 * The code to allow an event queue to be updated during a signal
1148 was missing. For main.c, a cntrl-c simulation termination wasn't
1151 * The simulation would not correctly restart if an event requested
1152 that the simulation be halted.
1154 * psim.c (psim_options): Add hack to -i option to optionally
1155 include a level vis -i2.
1156 (psim_usage): Document.

1175 * gen-idecode.c (print_run_until_stop_body): Call
1176 event_queue_process_events to clear possibly pending events before

1204 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1205 to be initialized independant of the rest of the simulation
1206 initalization. Otherwize a trace option explictly set from gdb
1207 could be overridden by hw_trace.
1209 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1211 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1212 debug.c. It could be much simpler.

1271 * The code that put values in and extracted values from the cache
1272 was too compilicated. The cache table did not allow values to be
1273 computed from cache entries. #defines could only be used when a
1274 cache was present, remove the restriction.
1276 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1277 scratch variable is defined when a cache entry is beinf
1278 filled. Change the definition of a COMPUTE variable to be defined
1279 when the cache entry is being used.
1280 * gen-icache.c: Update.
1282 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1298 * configure.in (enable-sim-icache): Clarify description. Make
1299 #define one of the defaults regardless of the cache. Probably
1300 should revamp and add a separate option.

3696 used to set the value of the trace options. Init this device (in
3697 psim_options) when ever the options are updated.
3699 Wed Jan 17 19:46:07 1996 Andrew Cagney <cagney@highland.com.au>
3701 * debug.h: Add trace_print_info, trace_print_device_tree and
3702 trace_dump_device_tree. The first is a replacement for the
3703 variable `print_info' found in main.c and sim_calls.c. The latter
3704 two enable the dumping of the entire device tree.
3706 * debug.c: Add to trace_description table.
3708 * main.c (main): Use above trace instead of local variable
3709 * sim_calls.c (sim_close): Ditto
3711 * device.c (device_tree_print_device): New. Prints the device
3712 tree in a format that is consistent with what can be parsed by the
3713 device tree load from file code.
3715 * psim.c (psim_create): Dump device tree if enabled. If nump
3716 selected, exit psim immediatly.
3718 Wed Jan 17 19:36:52 1996 Andrew Cagney <cagney@highland.com.au>
3720 * corefile-n.h (core_map_read_N): When mapping from an address to
3721 a device, do not subtract the devices base. The device its self
3722 can do this. Brings the behavour into line with OpenBoot.
3723 * corefile-n.h (core_map_write_N): Ditto
3724 * corefile.c (core_map_read_buffer): Ditto
3725 * corefile.c (core_map_write_buffer): Ditto
3727 * device_table.c (console_io_read_buffer_callback): Adjust to
3728 handle biased address.
3729 * device_table.c (console_io_write_buffer_callback): Ditto
3731 Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
3733 * device.c (attach_device_interrupt_edge): New. Interrupt model
3734 did not allow interrupts to be wired up as a general net (edges).
3735 Re-implement so that interrupt events can be passed to multiple
3736 controllers and interrupt controllers can further propogate
3739 * device.c (attach_device_interrupt_edge) : New, Ditto
3740 * device.c (detach_device_interrupt_edge) : New, Ditto
3741 * device.c (clean_device_interrupt_edges) : New, Ditto
3742 * device.c (device_interrupt_event) : New, Ditto
3743 * device.c (device_interrupt_attach) : New, Ditto
3744 * device.c (device_interrupt_detach) : New, Ditto
3745 * device.c (device_child_interrupt_attach) : New, Ditto
3746 * device.c (device_child_interrupt_detach) : New, Ditto
3748 * device.c (device_attach_interrupt) : Delete old
3749 * device.c (device_detach_interrupt) : Delete old
3750 * device.c (device_interrupt) : Delete old
3751 * device.c (device_interrupt_ack) : Delete old
3753 * device_table.c (unimp_*) : Update to match
3755 * device_table.c (icu_io_write_buffer_callback) : Update to use
3757 * device_table.c (icu_interrupt_event_callback) : Ditto
3759 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
3761 * device.c (external_to_device) : New function that provides a
3762 standard mapping between a devices internal representation (a
3763 pointer) and its external (or what is passed to a client)
3764 representation (a phandle). Implement using the cap object
3765 attached to the root node.
3767 * device.c (device_to_external) : Ditto
3768 * device.c (external_to_device_instance) : Ditto but for ihandle
3769 and device instance.
3770 * device.c (device_instance_to_external) : Ditto
3772 * Makefile (device.o): Add dependency on cap.
3774 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3775 needing to translate between internal and external representations
3776 changed to use the external_to_device et.al. device operations.
3777 * emul_chirp.c (chirp_emul_*) : Ditto
3779 * Makefile (emul_chirp.o): Remove dependency on cap
3781 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
3783 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
3784 on OpenBoot note section.
3786 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
3788 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3789 read/write calls for buffer transfers. This will cause a fault to
3790 occure if the transfer fails. CHRP catches the fault while the
3791 others suffer the consequences.
3792 (emul_read_buffer): Ditto.
3793 (emul_write_word): Ditto.
3794 (emul_read_word): Ditto.
3795 (emul_read_string): Ditto.
3797 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
3799 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
3800 emul_generic (emul_blr_instruction): Use a real blr instruction to
3801 return from a client service call.
3803 * emul_chirp.c (services): Add all OpenBoot services to table.
3805 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
3806 (emul_chirp_create) : Use names instead of numbers for
3807 instructions being stored in memory.
3809 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
3811 * Makefile.in (maintainer-clean): Remove .log, core and *.core
3812 (From NetBSD) files.
3814 Wed May 29 22:57:40 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
3816 * ChangeLog.00, ChangeLog: ChangeLog from gdb-4.16 becomes
