562 open syscall to the numbers supported by the host.
564 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
566 * sim-endian.h: Don't have parameters on macro definitions which
567 are simply renaming functions, to permit use of XCONCAT2 in both
568 the macro name and the arguments in a use of such a definition.
570 2000-11-15 Jim Blandy <jimb@redhat.com>
572 * sim_calls.c: Doc fix.
573 (sim_fetch_register, sim_store_register): Call

608 1999-05-08 Felix Lee <flee@cygnus.com>
610 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
611 * configure: Regenerated to track ../common/aclocal.m4 changes.
613 1999-04-02 Keith Seitz <keiths@cygnus.com>
615 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
616 the frequency at which the poll_quit callback is called.
617 (poll_quit_count): New global.
618 (sim_io_poll_quit): Only call the poll_quit callback
619 after the specified POLL_QUIT_INTERVAL.
621 1999-02-22 Jim Lemke <jlemke@cygnus.com>
623 * dc-complex: Force expansion on all bits of field BO.
624 Previously, the least-significant (prediction) bit was ignored.
625 * ppc-instructions (conditional branches): Implement mpc860c0 option.
626 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
627 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.

631 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
633 Make the simulator compatible with the MPC750. It would be nicer
634 to make this a real multi-sim, but that's more work than we have
636 * emul_generic.c (emul_add_tree_options): Only require strict
637 alignment if it was explicitly requested at configuration time.
638 Don't make it the default for little-endian machines.
639 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
640 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
641 THRM2, THRM3): Plop in the MPC750 SPR registers.
642 (DABR): This is weird. This was HID5, but the PPC spec says this
643 should be DABR; why did some random processor use it for something
644 else? The HID5 entry dates back to the original checkin of the
645 simulator code in 1995, so remove it.
646 * sim_calls.c (register_names): Delete this; since the user can
647 now change GDB's list of register names dynamically, we can't
648 pretend there's a static mapping here.
649 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
650 function to get the register name. That ought to be accurate.
651 However, we're changing a compile-time dependency (using the
652 REGISTER_NAMES macro) into a link- and run-time dependency
653 (calling REGISTER_NAME, which happens to be a function call on the
656 1999-01-22 Jim Lemke <jlemke@cygnus.com>

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

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

1065 * gen-icache.c: Generalize code handling XXX_is_NNN so that it
1066 works for normal and boolean table entries.
1068 * psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now

1129 determine the simulation speed by looking at the number of elapsed
1130 ticks recorded by the event queue.
1132 * psim.c (psim_write_register, psim_read_register): Force the cpu
1133 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1134 next cpu would be zero any way.
1136 * mon.c (mon_print_info): If possible, print the system cycle
1137 performance. This is an indication of the number of instructions
1140 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1142 * The code to allow an event queue to be updated during a signal
1143 was missing. For main.c, a cntrl-c simulation termination wasn't
1146 * The simulation would not correctly restart if an event requested
1147 that the simulation be halted.
1149 * psim.c (psim_options): Add hack to -i option to optionally
1150 include a level vis -i2.
1151 (psim_usage): Document.

1170 * gen-idecode.c (print_run_until_stop_body): Call
1171 event_queue_process_events to clear possibly pending events before

1199 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1200 to be initialized independant of the rest of the simulation
1201 initalization. Otherwize a trace option explictly set from gdb
1202 could be overridden by hw_trace.
1204 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1206 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1207 debug.c. It could be much simpler.
1209 Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

1266 * The code that put values in and extracted values from the cache
1267 was too compilicated. The cache table did not allow values to be
1268 computed from cache entries. #defines could only be used when a
1269 cache was present, remove the restriction.
1271 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1272 scratch variable is defined when a cache entry is beinf
1273 filled. Change the definition of a COMPUTE variable to be defined
1274 when the cache entry is being used.
1275 * gen-icache.c: Update.
1277 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1293 * configure.in (enable-sim-icache): Clarify description. Make
1294 #define one of the defaults regardless of the cache. Probably
1295 should revamp and add a separate option.

3698 variable `print_info' found in main.c and sim_calls.c. The latter
3699 two enable the dumping of the entire device tree.
3701 * debug.c: Add to trace_description table.
3703 * main.c (main): Use above trace instead of local variable
3704 * sim_calls.c (sim_close): Ditto
3706 * device.c (device_tree_print_device): New. Prints the device
3707 tree in a format that is consistent with what can be parsed by the
3708 device tree load from file code.
3710 * psim.c (psim_create): Dump device tree if enabled. If nump
3711 selected, exit psim immediatly.
3713 Wed Jan 17 19:36:52 1996 Andrew Cagney <cagney@highland.com.au>
3715 * corefile-n.h (core_map_read_N): When mapping from an address to
3716 a device, do not subtract the devices base. The device its self
3717 can do this. Brings the behavour into line with OpenBoot.
3718 * corefile-n.h (core_map_write_N): Ditto
3719 * corefile.c (core_map_read_buffer): Ditto
3720 * corefile.c (core_map_write_buffer): Ditto
3722 * device_table.c (console_io_read_buffer_callback): Adjust to
3723 handle biased address.
3724 * device_table.c (console_io_write_buffer_callback): Ditto
3726 Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
3728 * device.c (attach_device_interrupt_edge): New. Interrupt model
3729 did not allow interrupts to be wired up as a general net (edges).
3730 Re-implement so that interrupt events can be passed to multiple
3731 controllers and interrupt controllers can further propogate
3734 * device.c (attach_device_interrupt_edge) : New, Ditto
3735 * device.c (detach_device_interrupt_edge) : New, Ditto
3736 * device.c (clean_device_interrupt_edges) : New, Ditto
3737 * device.c (device_interrupt_event) : New, Ditto
3738 * device.c (device_interrupt_attach) : New, Ditto
3739 * device.c (device_interrupt_detach) : New, Ditto
3740 * device.c (device_child_interrupt_attach) : New, Ditto
3741 * device.c (device_child_interrupt_detach) : New, Ditto
3743 * device.c (device_attach_interrupt) : Delete old
3744 * device.c (device_detach_interrupt) : Delete old
3745 * device.c (device_interrupt) : Delete old
3746 * device.c (device_interrupt_ack) : Delete old
3748 * device_table.c (unimp_*) : Update to match
3750 * device_table.c (icu_io_write_buffer_callback) : Update to use
3752 * device_table.c (icu_interrupt_event_callback) : Ditto
3754 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
3756 * device.c (external_to_device) : New function that provides a
3757 standard mapping between a devices internal representation (a
3758 pointer) and its external (or what is passed to a client)
3759 representation (a phandle). Implement using the cap object
3760 attached to the root node.
3762 * device.c (device_to_external) : Ditto
3763 * device.c (external_to_device_instance) : Ditto but for ihandle
3764 and device instance.
3765 * device.c (device_instance_to_external) : Ditto
3767 * Makefile (device.o): Add dependency on cap.
3769 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3770 needing to translate between internal and external representations
3771 changed to use the external_to_device et.al. device operations.
3772 * emul_chirp.c (chirp_emul_*) : Ditto
3774 * Makefile (emul_chirp.o): Remove dependency on cap
3776 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
3778 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
3779 on OpenBoot note section.
3781 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
3783 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3784 read/write calls for buffer transfers. This will cause a fault to
3785 occure if the transfer fails. CHRP catches the fault while the
3786 others suffer the consequences.
3787 (emul_read_buffer): Ditto.
3788 (emul_write_word): Ditto.
3789 (emul_read_word): Ditto.
3790 (emul_read_string): Ditto.
3792 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
3794 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
3795 emul_generic (emul_blr_instruction): Use a real blr instruction to
3796 return from a client service call.
3798 * emul_chirp.c (services): Add all OpenBoot services to table.
3800 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
3801 (emul_chirp_create) : Use names instead of numbers for
3802 instructions being stored in memory.
3804 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
3806 * Makefile.in (maintainer-clean): Remove .log, core and *.core
3807 (From NetBSD) files.
3809 Wed May 29 22:57:40 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
3811 * ChangeLog.00, ChangeLog: ChangeLog from gdb-4.16 becomes
