604 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
606 * sim-endian.h: Don't have parameters on macro definitions which
607 are simply renaming functions, to permit use of XCONCAT2 in both
608 the macro name and the arguments in a use of such a definition.
610 2000-11-15 Jim Blandy <jimb@redhat.com>
612 * sim_calls.c: Doc fix.
613 (sim_fetch_register, sim_store_register): Call

648 1999-05-08 Felix Lee <flee@cygnus.com>
650 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
651 * configure: Regenerated to track ../common/aclocal.m4 changes.
653 1999-04-02 Keith Seitz <keiths@cygnus.com>

659 after the specified POLL_QUIT_INTERVAL.
661 1999-02-22 Jim Lemke <jlemke@cygnus.com>
663 * dc-complex: Force expansion on all bits of field BO.
664 Previously, the least-significant (prediction) bit was ignored.

671 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
673 Make the simulator compatible with the MPC750. It would be nicer
674 to make this a real multi-sim, but that's more work than we have
676 * emul_generic.c (emul_add_tree_options): Only require strict
677 alignment if it was explicitly requested at configuration time.
678 Don't make it the default for little-endian machines.
679 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
680 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
681 THRM2, THRM3): Plop in the MPC750 SPR registers.
682 (DABR): This is weird. This was HID5, but the PPC spec says this
683 should be DABR; why did some random processor use it for something
684 else? The HID5 entry dates back to the original checkin of the
685 simulator code in 1995, so remove it.
686 * sim_calls.c (register_names): Delete this; since the user can
687 now change GDB's list of register names dynamically, we can't
688 pretend there's a static mapping here.
689 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
690 function to get the register name. That ought to be accurate.
691 However, we're changing a compile-time dependency (using the
692 REGISTER_NAMES macro) into a link- and run-time dependency
693 (calling REGISTER_NAME, which happens to be a function call on the
696 1999-01-22 Jim Lemke <jlemke@cygnus.com>

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

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

1172 * psim.c (psim_write_register, psim_read_register): Force the cpu
1173 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1174 next cpu would be zero any way.
1176 * mon.c (mon_print_info): If possible, print the system cycle
1177 performance. This is an indication of the number of instructions
1180 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1182 * The code to allow an event queue to be updated during a signal
1183 was missing. For main.c, a cntrl-c simulation termination wasn't
1186 * The simulation would not correctly restart if an event requested
1187 that the simulation be halted.
1189 * psim.c (psim_options): Add hack to -i option to optionally
1190 include a level vis -i2.
1191 (psim_usage): Document.

1210 * gen-idecode.c (print_run_until_stop_body): Call
1211 event_queue_process_events to clear possibly pending events before

1239 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1240 to be initialized independant of the rest of the simulation
1241 initalization. Otherwize a trace option explictly set from gdb
1242 could be overridden by hw_trace.
1244 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1246 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1247 debug.c. It could be much simpler.

1307 was too compilicated. The cache table did not allow values to be
1308 computed from cache entries. #defines could only be used when a
1309 cache was present, remove the restriction.
1311 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1312 scratch variable is defined when a cache entry is beinf
1313 filled. Change the definition of a COMPUTE variable to be defined
1314 when the cache entry is being used.
1315 * gen-icache.c: Update.
1317 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1333 * configure.in (enable-sim-icache): Clarify description. Make
1334 #define one of the defaults regardless of the cache. Probably
1335 should revamp and add a separate option.

3700 * psim.c(psim_options): Parse the psim options, installing their
3701 value in the device tree. Options are now first entered into a
3702 device tree and then extracted out again when needed. This allows
3703 greater flexability in configuration.
3705 * psim.c (psim_tree): Returns a basic device tree ready for
3706 parsing by psim_options.
3707 * psim.c (psim_usage): New. Give usage to varing levels of detail
3708 according to the verbosity. In turn output device and trace
3711 * main.c (main): Update to use new system
3712 * sim_calls.c (sim_open, sim_do_command): Ditto
3714 * psim.c (psim_options): Add `r' option - ram size.
3715 * psim.c (psim_options): Add `o' option - openboot tree entry.
3716 * psim.c (psim_options): Add `h'/`H' options - more help.
3718 * debug.c (trace_usage): Add more detailed help.
3719 * device.c (device_usage): New. Output help including a list of
3720 the devices currently available in the device table.
3721 * device_table.c: Add usage operator to each device.
3723 * corefile.c (core_create, core_device_create): Adjust so that the
3724 core device is created earlier for psim_tree(). Core can later be
3727 * psim.c (psim_create): Update to handle above way of creating
3728 things. Extract all information from the device tree.
3730 * device_tree.c (trace_*): New device node, its properties are
3731 used to set the value of the trace options. Init this device (in
3732 psim_options) when ever the options are updated.
3734 Wed Jan 17 19:46:07 1996 Andrew Cagney <cagney@highland.com.au>
3736 * debug.h: Add trace_print_info, trace_print_device_tree and
3737 trace_dump_device_tree. The first is a replacement for the
3738 variable `print_info' found in main.c and sim_calls.c. The latter
3739 two enable the dumping of the entire device tree.
3741 * debug.c: Add to trace_description table.
3743 * main.c (main): Use above trace instead of local variable
3744 * sim_calls.c (sim_close): Ditto
3746 * device.c (device_tree_print_device): New. Prints the device
3747 tree in a format that is consistent with what can be parsed by the
3748 device tree load from file code.
3750 * psim.c (psim_create): Dump device tree if enabled. If nump
3751 selected, exit psim immediatly.
3753 Wed Jan 17 19:36:52 1996 Andrew Cagney <cagney@highland.com.au>
3755 * corefile-n.h (core_map_read_N): When mapping from an address to
3756 a device, do not subtract the devices base. The device its self
3757 can do this. Brings the behavour into line with OpenBoot.
3758 * corefile-n.h (core_map_write_N): Ditto
3759 * corefile.c (core_map_read_buffer): Ditto
3760 * corefile.c (core_map_write_buffer): Ditto
3762 * device_table.c (console_io_read_buffer_callback): Adjust to
3763 handle biased address.
3764 * device_table.c (console_io_write_buffer_callback): Ditto
3766 Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
3768 * device.c (attach_device_interrupt_edge): New. Interrupt model
3769 did not allow interrupts to be wired up as a general net (edges).
3770 Re-implement so that interrupt events can be passed to multiple
3771 controllers and interrupt controllers can further propogate
3774 * device.c (attach_device_interrupt_edge) : New, Ditto
3775 * device.c (detach_device_interrupt_edge) : New, Ditto
3776 * device.c (clean_device_interrupt_edges) : New, Ditto
3777 * device.c (device_interrupt_event) : New, Ditto
3778 * device.c (device_interrupt_attach) : New, Ditto
3779 * device.c (device_interrupt_detach) : New, Ditto
3780 * device.c (device_child_interrupt_attach) : New, Ditto
3781 * device.c (device_child_interrupt_detach) : New, Ditto
3783 * device.c (device_attach_interrupt) : Delete old
3784 * device.c (device_detach_interrupt) : Delete old
3785 * device.c (device_interrupt) : Delete old
3786 * device.c (device_interrupt_ack) : Delete old
3788 * device_table.c (unimp_*) : Update to match
3790 * device_table.c (icu_io_write_buffer_callback) : Update to use
3792 * device_table.c (icu_interrupt_event_callback) : Ditto
3794 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
3796 * device.c (external_to_device) : New function that provides a
3797 standard mapping between a devices internal representation (a
3798 pointer) and its external (or what is passed to a client)
3799 representation (a phandle). Implement using the cap object
3800 attached to the root node.
3802 * device.c (device_to_external) : Ditto
3803 * device.c (external_to_device_instance) : Ditto but for ihandle
3804 and device instance.
3805 * device.c (device_instance_to_external) : Ditto
3807 * Makefile (device.o): Add dependency on cap.
3809 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3810 needing to translate between internal and external representations
3811 changed to use the external_to_device et.al. device operations.
3812 * emul_chirp.c (chirp_emul_*) : Ditto
3814 * Makefile (emul_chirp.o): Remove dependency on cap
3816 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
3818 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
3819 on OpenBoot note section.
3821 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
3823 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3824 read/write calls for buffer transfers. This will cause a fault to
3825 occure if the transfer fails. CHRP catches the fault while the
3826 others suffer the consequences.
3827 (emul_read_buffer): Ditto.
3828 (emul_write_word): Ditto.
3829 (emul_read_word): Ditto.
3830 (emul_read_string): Ditto.
3832 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
3834 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
