553 open syscall to the numbers supported by the host.
555 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
557 * sim-endian.h: Don't have parameters on macro definitions which
558 are simply renaming functions, to permit use of XCONCAT2 in both
559 the macro name and the arguments in a use of such a definition.
561 2000-11-15 Jim Blandy <jimb@redhat.com>
563 * sim_calls.c: Doc fix.
564 (sim_fetch_register, sim_store_register): Call

599 1999-05-08 Felix Lee <flee@cygnus.com>
601 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
602 * configure: Regenerated to track ../common/aclocal.m4 changes.
604 1999-04-02 Keith Seitz <keiths@cygnus.com>
606 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
607 the frequency at which the poll_quit callback is called.
608 (poll_quit_count): New global.
609 (sim_io_poll_quit): Only call the poll_quit callback
610 after the specified POLL_QUIT_INTERVAL.
612 1999-02-22 Jim Lemke <jlemke@cygnus.com>
614 * dc-complex: Force expansion on all bits of field BO.
615 Previously, the least-significant (prediction) bit was ignored.
616 * ppc-instructions (conditional branches): Implement mpc860c0 option.

622 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
624 Make the simulator compatible with the MPC750. It would be nicer
625 to make this a real multi-sim, but that's more work than we have
627 * emul_generic.c (emul_add_tree_options): Only require strict
628 alignment if it was explicitly requested at configuration time.
629 Don't make it the default for little-endian machines.
630 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
631 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
632 THRM2, THRM3): Plop in the MPC750 SPR registers.
633 (DABR): This is weird. This was HID5, but the PPC spec says this
634 should be DABR; why did some random processor use it for something
635 else? The HID5 entry dates back to the original checkin of the
636 simulator code in 1995, so remove it.
637 * sim_calls.c (register_names): Delete this; since the user can
638 now change GDB's list of register names dynamically, we can't
639 pretend there's a static mapping here.
640 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
641 function to get the register name. That ought to be accurate.
642 However, we're changing a compile-time dependency (using the
643 REGISTER_NAMES macro) into a link- and run-time dependency
644 (calling REGISTER_NAME, which happens to be a function call on the
647 1999-01-22 Jim Lemke <jlemke@cygnus.com>

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

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

1123 * psim.c (psim_write_register, psim_read_register): Force the cpu
1124 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1125 next cpu would be zero any way.
1127 * mon.c (mon_print_info): If possible, print the system cycle
1128 performance. This is an indication of the number of instructions
1131 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1133 * The code to allow an event queue to be updated during a signal
1134 was missing. For main.c, a cntrl-c simulation termination wasn't
1137 * The simulation would not correctly restart if an event requested
1138 that the simulation be halted.
1140 * psim.c (psim_options): Add hack to -i option to optionally
1141 include a level vis -i2.
1142 (psim_usage): Document.

1190 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1191 to be initialized independant of the rest of the simulation
1192 initalization. Otherwize a trace option explictly set from gdb
1193 could be overridden by hw_trace.
1195 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1197 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1198 debug.c. It could be much simpler.

1258 was too compilicated. The cache table did not allow values to be
1259 computed from cache entries. #defines could only be used when a
1260 cache was present, remove the restriction.
1262 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1263 scratch variable is defined when a cache entry is beinf
1264 filled. Change the definition of a COMPUTE variable to be defined
1265 when the cache entry is being used.
1266 * gen-icache.c: Update.
1268 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1284 * configure.in (enable-sim-icache): Clarify description. Make
1285 #define one of the defaults regardless of the cache. Probably
1286 should revamp and add a separate option.

3692 * debug.c: Add to trace_description table.
3694 * main.c (main): Use above trace instead of local variable
3695 * sim_calls.c (sim_close): Ditto
3697 * device.c (device_tree_print_device): New. Prints the device
3698 tree in a format that is consistent with what can be parsed by the
3699 device tree load from file code.
3701 * psim.c (psim_create): Dump device tree if enabled. If nump
3702 selected, exit psim immediatly.
3704 Wed Jan 17 19:36:52 1996 Andrew Cagney <cagney@highland.com.au>
3706 * corefile-n.h (core_map_read_N): When mapping from an address to
3707 a device, do not subtract the devices base. The device its self
3708 can do this. Brings the behavour into line with OpenBoot.
3709 * corefile-n.h (core_map_write_N): Ditto
3710 * corefile.c (core_map_read_buffer): Ditto
3711 * corefile.c (core_map_write_buffer): Ditto
3713 * device_table.c (console_io_read_buffer_callback): Adjust to
3714 handle biased address.
3715 * device_table.c (console_io_write_buffer_callback): Ditto
3717 Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
3719 * device.c (attach_device_interrupt_edge): New. Interrupt model
3720 did not allow interrupts to be wired up as a general net (edges).
3721 Re-implement so that interrupt events can be passed to multiple
3722 controllers and interrupt controllers can further propogate
3725 * device.c (attach_device_interrupt_edge) : New, Ditto
3726 * device.c (detach_device_interrupt_edge) : New, Ditto
3727 * device.c (clean_device_interrupt_edges) : New, Ditto
3728 * device.c (device_interrupt_event) : New, Ditto
3729 * device.c (device_interrupt_attach) : New, Ditto
3730 * device.c (device_interrupt_detach) : New, Ditto
3731 * device.c (device_child_interrupt_attach) : New, Ditto
3732 * device.c (device_child_interrupt_detach) : New, Ditto
3734 * device.c (device_attach_interrupt) : Delete old
3735 * device.c (device_detach_interrupt) : Delete old
3736 * device.c (device_interrupt) : Delete old
3737 * device.c (device_interrupt_ack) : Delete old
3739 * device_table.c (unimp_*) : Update to match
3741 * device_table.c (icu_io_write_buffer_callback) : Update to use
3743 * device_table.c (icu_interrupt_event_callback) : Ditto
3745 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
3747 * device.c (external_to_device) : New function that provides a
3748 standard mapping between a devices internal representation (a
3749 pointer) and its external (or what is passed to a client)
3750 representation (a phandle). Implement using the cap object
3751 attached to the root node.
3753 * device.c (device_to_external) : Ditto
3754 * device.c (external_to_device_instance) : Ditto but for ihandle
3755 and device instance.
3756 * device.c (device_instance_to_external) : Ditto
3758 * Makefile (device.o): Add dependency on cap.
3760 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3761 needing to translate between internal and external representations
3762 changed to use the external_to_device et.al. device operations.
3763 * emul_chirp.c (chirp_emul_*) : Ditto
3765 * Makefile (emul_chirp.o): Remove dependency on cap
3767 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
3769 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
3770 on OpenBoot note section.
3772 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
3774 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3775 read/write calls for buffer transfers. This will cause a fault to
3776 occure if the transfer fails. CHRP catches the fault while the
3777 others suffer the consequences.
3778 (emul_read_buffer): Ditto.
3779 (emul_write_word): Ditto.
3780 (emul_read_word): Ditto.
3781 (emul_read_string): Ditto.
3783 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
3785 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
3786 emul_generic (emul_blr_instruction): Use a real blr instruction to
3787 return from a client service call.
3789 * emul_chirp.c (services): Add all OpenBoot services to table.
3791 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
3792 (emul_chirp_create) : Use names instead of numbers for
3793 instructions being stored in memory.
3795 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
3797 * Makefile.in (maintainer-clean): Remove .log, core and *.core
3798 (From NetBSD) files.
3800 Wed May 29 22:57:40 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
