535 open syscall to the numbers supported by the host.
537 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
539 * sim-endian.h: Don't have parameters on macro definitions which
540 are simply renaming functions, to permit use of XCONCAT2 in both
541 the macro name and the arguments in a use of such a definition.
543 2000-11-15 Jim Blandy <jimb@redhat.com>
545 * sim_calls.c: Doc fix.
546 (sim_fetch_register, sim_store_register): Call

577 Thu Sep 2 18:15:53 1999 Andrew Cagney <cagney@b1.cygnus.com>
579 * configure: Regenerated to track ../common/aclocal.m4 changes.
581 1999-05-08 Felix Lee <flee@cygnus.com>
583 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
584 * configure: Regenerated to track ../common/aclocal.m4 changes.
586 1999-04-02 Keith Seitz <keiths@cygnus.com>
588 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
589 the frequency at which the poll_quit callback is called.

592 after the specified POLL_QUIT_INTERVAL.
594 1999-02-22 Jim Lemke <jlemke@cygnus.com>
596 * dc-complex: Force expansion on all bits of field BO.
597 Previously, the least-significant (prediction) bit was ignored.
598 * ppc-instructions (conditional branches): Implement mpc860c0 option.
599 * igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
600 * psim.c (is_num, psim_options): Added parsing for mpc860c0 option.

604 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
606 Make the simulator compatible with the MPC750. It would be nicer
607 to make this a real multi-sim, but that's more work than we have
609 * emul_generic.c (emul_add_tree_options): Only require strict
610 alignment if it was explicitly requested at configuration time.
611 Don't make it the default for little-endian machines.
612 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
613 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
614 THRM2, THRM3): Plop in the MPC750 SPR registers.
615 (DABR): This is weird. This was HID5, but the PPC spec says this
616 should be DABR; why did some random processor use it for something
617 else? The HID5 entry dates back to the original checkin of the
618 simulator code in 1995, so remove it.
619 * sim_calls.c (register_names): Delete this; since the user can
620 now change GDB's list of register names dynamically, we can't
621 pretend there's a static mapping here.
622 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
623 function to get the register name. That ought to be accurate.
624 However, we're changing a compile-time dependency (using the
625 REGISTER_NAMES macro) into a link- and run-time dependency
626 (calling REGISTER_NAME, which happens to be a function call on the
629 1999-01-22 Jim Lemke <jlemke@cygnus.com>

636 These changes are currently under #ifdef WITH_OPTION_MPC860C0.
638 1998-12-01 Ken Raeburn <raeburn@cygnus.com>

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

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

1102 determine the simulation speed by looking at the number of elapsed
1103 ticks recorded by the event queue.
1105 * psim.c (psim_write_register, psim_read_register): Force the cpu
1106 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1107 next cpu would be zero any way.
1109 * mon.c (mon_print_info): If possible, print the system cycle
1110 performance. This is an indication of the number of instructions
1113 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1115 * The code to allow an event queue to be updated during a signal
1116 was missing. For main.c, a cntrl-c simulation termination wasn't
1119 * The simulation would not correctly restart if an event requested
1120 that the simulation be halted.
1122 * psim.c (psim_options): Add hack to -i option to optionally
1123 include a level vis -i2.
1124 (psim_usage): Document.

1143 * gen-idecode.c (print_run_until_stop_body): Call
1144 event_queue_process_events to clear possibly pending events before

1172 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1173 to be initialized independant of the rest of the simulation
1174 initalization. Otherwize a trace option explictly set from gdb
1175 could be overridden by hw_trace.
1177 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1179 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1180 debug.c. It could be much simpler.

1240 was too compilicated. The cache table did not allow values to be
1241 computed from cache entries. #defines could only be used when a
1242 cache was present, remove the restriction.
1244 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1245 scratch variable is defined when a cache entry is beinf
1246 filled. Change the definition of a COMPUTE variable to be defined
1247 when the cache entry is being used.
1248 * gen-icache.c: Update.
1250 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1266 * configure.in (enable-sim-icache): Clarify description. Make
1267 #define one of the defaults regardless of the cache. Probably
1268 should revamp and add a separate option.

3693 * corefile.c (core_map_write_buffer): Ditto
3695 * device_table.c (console_io_read_buffer_callback): Adjust to
3696 handle biased address.
3697 * device_table.c (console_io_write_buffer_callback): Ditto
3699 Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
3701 * device.c (attach_device_interrupt_edge): New. Interrupt model
3702 did not allow interrupts to be wired up as a general net (edges).
3703 Re-implement so that interrupt events can be passed to multiple
3704 controllers and interrupt controllers can further propogate
3707 * device.c (attach_device_interrupt_edge) : New, Ditto
3708 * device.c (detach_device_interrupt_edge) : New, Ditto

3716 * device.c (device_attach_interrupt) : Delete old
3717 * device.c (device_detach_interrupt) : Delete old
3718 * device.c (device_interrupt) : Delete old
3719 * device.c (device_interrupt_ack) : Delete old
3721 * device_table.c (unimp_*) : Update to match
3723 * device_table.c (icu_io_write_buffer_callback) : Update to use
3725 * device_table.c (icu_interrupt_event_callback) : Ditto
3727 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
3729 * device.c (external_to_device) : New function that provides a
3730 standard mapping between a devices internal representation (a
3731 pointer) and its external (or what is passed to a client)
3732 representation (a phandle). Implement using the cap object
3733 attached to the root node.
3735 * device.c (device_to_external) : Ditto
3736 * device.c (external_to_device_instance) : Ditto but for ihandle
3737 and device instance.
3738 * device.c (device_instance_to_external) : Ditto
3740 * Makefile (device.o): Add dependency on cap.
3742 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3743 needing to translate between internal and external representations
3744 changed to use the external_to_device et.al. device operations.
3745 * emul_chirp.c (chirp_emul_*) : Ditto
3747 * Makefile (emul_chirp.o): Remove dependency on cap
3749 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
3751 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
3752 on OpenBoot note section.
3754 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
3756 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3757 read/write calls for buffer transfers. This will cause a fault to
3758 occure if the transfer fails. CHRP catches the fault while the
3759 others suffer the consequences.
3760 (emul_read_buffer): Ditto.
3761 (emul_write_word): Ditto.
3762 (emul_read_word): Ditto.
3763 (emul_read_string): Ditto.
3765 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
3767 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
3768 emul_generic (emul_blr_instruction): Use a real blr instruction to
3769 return from a client service call.
3771 * emul_chirp.c (services): Add all OpenBoot services to table.
3773 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
3774 (emul_chirp_create) : Use names instead of numbers for
3775 instructions being stored in memory.
3777 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
3779 * Makefile.in (maintainer-clean): Remove .log, core and *.core
3780 (From NetBSD) files.
