557 open syscall to the numbers supported by the host.
559 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
561 * sim-endian.h: Don't have parameters on macro definitions which
562 are simply renaming functions, to permit use of XCONCAT2 in both
563 the macro name and the arguments in a use of such a definition.
565 2000-11-15 Jim Blandy <jimb@redhat.com>
567 * sim_calls.c: Doc fix.
568 (sim_fetch_register, sim_store_register): Call

603 1999-05-08 Felix Lee <flee@cygnus.com>
605 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
606 * configure: Regenerated to track ../common/aclocal.m4 changes.
608 1999-04-02 Keith Seitz <keiths@cygnus.com>
610 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
611 the frequency at which the poll_quit callback is called.
612 (poll_quit_count): New global.
613 (sim_io_poll_quit): Only call the poll_quit callback
614 after the specified POLL_QUIT_INTERVAL.
616 1999-02-22 Jim Lemke <jlemke@cygnus.com>
618 * dc-complex: Force expansion on all bits of field BO.
619 Previously, the least-significant (prediction) bit was ignored.
620 * ppc-instructions (conditional branches): Implement mpc860c0 option.
621 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
622 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.

626 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
628 Make the simulator compatible with the MPC750. It would be nicer
629 to make this a real multi-sim, but that's more work than we have
631 * emul_generic.c (emul_add_tree_options): Only require strict
632 alignment if it was explicitly requested at configuration time.
633 Don't make it the default for little-endian machines.
634 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
635 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
636 THRM2, THRM3): Plop in the MPC750 SPR registers.
637 (DABR): This is weird. This was HID5, but the PPC spec says this
638 should be DABR; why did some random processor use it for something
639 else? The HID5 entry dates back to the original checkin of the
640 simulator code in 1995, so remove it.
641 * sim_calls.c (register_names): Delete this; since the user can
642 now change GDB's list of register names dynamically, we can't
643 pretend there's a static mapping here.
644 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
645 function to get the register name. That ought to be accurate.
646 However, we're changing a compile-time dependency (using the
647 REGISTER_NAMES macro) into a link- and run-time dependency
648 (calling REGISTER_NAME, which happens to be a function call on the
651 1999-01-22 Jim Lemke <jlemke@cygnus.com>

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

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

1127 * psim.c (psim_write_register, psim_read_register): Force the cpu
1128 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1129 next cpu would be zero any way.
1131 * mon.c (mon_print_info): If possible, print the system cycle
1132 performance. This is an indication of the number of instructions
1135 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1137 * The code to allow an event queue to be updated during a signal
1138 was missing. For main.c, a cntrl-c simulation termination wasn't
1141 * The simulation would not correctly restart if an event requested
1142 that the simulation be halted.
1144 * psim.c (psim_options): Add hack to -i option to optionally
1145 include a level vis -i2.
1146 (psim_usage): Document.

1194 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1195 to be initialized independant of the rest of the simulation
1196 initalization. Otherwize a trace option explictly set from gdb
1197 could be overridden by hw_trace.
1199 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1201 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1202 debug.c. It could be much simpler.

1262 was too compilicated. The cache table did not allow values to be
1263 computed from cache entries. #defines could only be used when a
1264 cache was present, remove the restriction.
1266 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1267 scratch variable is defined when a cache entry is beinf
1268 filled. Change the definition of a COMPUTE variable to be defined
1269 when the cache entry is being used.
1270 * gen-icache.c: Update.
1272 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1288 * configure.in (enable-sim-icache): Clarify description. Make
1289 #define one of the defaults regardless of the cache. Probably
1290 should revamp and add a separate option.

3696 * debug.c: Add to trace_description table.
3698 * main.c (main): Use above trace instead of local variable
3699 * sim_calls.c (sim_close): Ditto
3701 * device.c (device_tree_print_device): New. Prints the device
3702 tree in a format that is consistent with what can be parsed by the
3703 device tree load from file code.
3705 * psim.c (psim_create): Dump device tree if enabled. If nump
3706 selected, exit psim immediatly.
3708 Wed Jan 17 19:36:52 1996 Andrew Cagney <cagney@highland.com.au>
3710 * corefile-n.h (core_map_read_N): When mapping from an address to
3711 a device, do not subtract the devices base. The device its self
3712 can do this. Brings the behavour into line with OpenBoot.
3713 * corefile-n.h (core_map_write_N): Ditto
3714 * corefile.c (core_map_read_buffer): Ditto
3715 * corefile.c (core_map_write_buffer): Ditto
3717 * device_table.c (console_io_read_buffer_callback): Adjust to
3718 handle biased address.
3719 * device_table.c (console_io_write_buffer_callback): Ditto
3721 Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
3723 * device.c (attach_device_interrupt_edge): New. Interrupt model
3724 did not allow interrupts to be wired up as a general net (edges).
3725 Re-implement so that interrupt events can be passed to multiple
3726 controllers and interrupt controllers can further propogate
3729 * device.c (attach_device_interrupt_edge) : New, Ditto
3730 * device.c (detach_device_interrupt_edge) : New, Ditto
3731 * device.c (clean_device_interrupt_edges) : New, Ditto
3732 * device.c (device_interrupt_event) : New, Ditto
3733 * device.c (device_interrupt_attach) : New, Ditto
3734 * device.c (device_interrupt_detach) : New, Ditto
3735 * device.c (device_child_interrupt_attach) : New, Ditto
3736 * device.c (device_child_interrupt_detach) : New, Ditto
3738 * device.c (device_attach_interrupt) : Delete old
3739 * device.c (device_detach_interrupt) : Delete old
3740 * device.c (device_interrupt) : Delete old
3741 * device.c (device_interrupt_ack) : Delete old
3743 * device_table.c (unimp_*) : Update to match
3745 * device_table.c (icu_io_write_buffer_callback) : Update to use
3747 * device_table.c (icu_interrupt_event_callback) : Ditto
3749 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
3751 * device.c (external_to_device) : New function that provides a
3752 standard mapping between a devices internal representation (a
3753 pointer) and its external (or what is passed to a client)
3754 representation (a phandle). Implement using the cap object
3755 attached to the root node.
3757 * device.c (device_to_external) : Ditto
3758 * device.c (external_to_device_instance) : Ditto but for ihandle
3759 and device instance.
3760 * device.c (device_instance_to_external) : Ditto
3762 * Makefile (device.o): Add dependency on cap.
3764 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3765 needing to translate between internal and external representations
3766 changed to use the external_to_device et.al. device operations.
3767 * emul_chirp.c (chirp_emul_*) : Ditto
3769 * Makefile (emul_chirp.o): Remove dependency on cap
3771 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
3773 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
3774 on OpenBoot note section.
3776 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
3778 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3779 read/write calls for buffer transfers. This will cause a fault to
3780 occure if the transfer fails. CHRP catches the fault while the
3781 others suffer the consequences.
3782 (emul_read_buffer): Ditto.
3783 (emul_write_word): Ditto.
3784 (emul_read_word): Ditto.
3785 (emul_read_string): Ditto.
3787 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
3789 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
3790 emul_generic (emul_blr_instruction): Use a real blr instruction to
3791 return from a client service call.
3793 * emul_chirp.c (services): Add all OpenBoot services to table.
3795 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
3796 (emul_chirp_create) : Use names instead of numbers for
3797 instructions being stored in memory.
3799 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
3801 * Makefile.in (maintainer-clean): Remove .log, core and *.core
3802 (From NetBSD) files.
3804 Wed May 29 22:57:40 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
