587 open syscall to the numbers supported by the host.
589 2000-12-12 Geoffrey Keating <geoffk@redhat.com>
591 * sim-endian.h: Don't have parameters on macro definitions which
592 are simply renaming functions, to permit use of XCONCAT2 in both
593 the macro name and the arguments in a use of such a definition.
595 2000-11-15 Jim Blandy <jimb@redhat.com>
597 * sim_calls.c: Doc fix.
598 (sim_fetch_register, sim_store_register): Call

633 1999-05-08 Felix Lee <flee@cygnus.com>
635 * configure.in: Use AC_EXEEXT instead of AM_EXEEXT.
636 * configure: Regenerated to track ../common/aclocal.m4 changes.
638 1999-04-02 Keith Seitz <keiths@cygnus.com>
640 * sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
641 the frequency at which the poll_quit callback is called.

644 after the specified POLL_QUIT_INTERVAL.
646 1999-02-22 Jim Lemke <jlemke@cygnus.com>
648 * dc-complex: Force expansion on all bits of field BO.
649 Previously, the least-significant (prediction) bit was ignored.

656 1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
658 Make the simulator compatible with the MPC750. It would be nicer
659 to make this a real multi-sim, but that's more work than we have
661 * emul_generic.c (emul_add_tree_options): Only require strict
662 alignment if it was explicitly requested at configuration time.
663 Don't make it the default for little-endian machines.
664 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
665 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
666 THRM2, THRM3): Plop in the MPC750 SPR registers.
667 (DABR): This is weird. This was HID5, but the PPC spec says this
668 should be DABR; why did some random processor use it for something
669 else? The HID5 entry dates back to the original checkin of the
670 simulator code in 1995, so remove it.
671 * sim_calls.c (register_names): Delete this; since the user can
672 now change GDB's list of register names dynamically, we can't
673 pretend there's a static mapping here.
674 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
675 function to get the register name. That ought to be accurate.
676 However, we're changing a compile-time dependency (using the
677 REGISTER_NAMES macro) into a link- and run-time dependency
678 (calling REGISTER_NAME, which happens to be a function call on the
681 1999-01-22 Jim Lemke <jlemke@cygnus.com>

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

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

1154 determine the simulation speed by looking at the number of elapsed
1155 ticks recorded by the event queue.
1157 * psim.c (psim_write_register, psim_read_register): Force the cpu
1158 to zero when it is either of `-1' or `nr_cpus'. In both cases the
1159 next cpu would be zero any way.
1161 * mon.c (mon_print_info): If possible, print the system cycle
1162 performance. This is an indication of the number of instructions
1165 Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
1167 * The code to allow an event queue to be updated during a signal
1168 was missing. For main.c, a cntrl-c simulation termination wasn't
1171 * The simulation would not correctly restart if an event requested
1172 that the simulation be halted.
1174 * psim.c (psim_options): Add hack to -i option to optionally
1175 include a level vis -i2.
1176 (psim_usage): Document.

1195 * gen-idecode.c (print_run_until_stop_body): Call
1196 event_queue_process_events to clear possibly pending events before

1224 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1225 to be initialized independant of the rest of the simulation
1226 initalization. Otherwize a trace option explictly set from gdb
1227 could be overridden by hw_trace.
1229 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1231 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
1232 debug.c. It could be much simpler.

1292 was too compilicated. The cache table did not allow values to be
1293 computed from cache entries. #defines could only be used when a
1294 cache was present, remove the restriction.
1296 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
1297 scratch variable is defined when a cache entry is beinf
1298 filled. Change the definition of a COMPUTE variable to be defined
1299 when the cache entry is being used.
1300 * gen-icache.c: Update.
1302 * ld-cache.h, ld-cache.c: Change field names so that their meaning

1318 * configure.in (enable-sim-icache): Clarify description. Make
1319 #define one of the defaults regardless of the cache. Probably
1320 should revamp and add a separate option.

3700 * psim.c (psim_options): Add `o' option - openboot tree entry.
3701 * psim.c (psim_options): Add `h'/`H' options - more help.
3703 * debug.c (trace_usage): Add more detailed help.
3704 * device.c (device_usage): New. Output help including a list of
3705 the devices currently available in the device table.
3706 * device_table.c: Add usage operator to each device.
3708 * corefile.c (core_create, core_device_create): Adjust so that the
3709 core device is created earlier for psim_tree(). Core can later be
3712 * psim.c (psim_create): Update to handle above way of creating
3713 things. Extract all information from the device tree.
3715 * device_tree.c (trace_*): New device node, its properties are
3716 used to set the value of the trace options. Init this device (in
3717 psim_options) when ever the options are updated.
3719 Wed Jan 17 19:46:07 1996 Andrew Cagney <cagney@highland.com.au>
3721 * debug.h: Add trace_print_info, trace_print_device_tree and
3722 trace_dump_device_tree. The first is a replacement for the
3723 variable `print_info' found in main.c and sim_calls.c. The latter
3724 two enable the dumping of the entire device tree.
3726 * debug.c: Add to trace_description table.
3728 * main.c (main): Use above trace instead of local variable
3729 * sim_calls.c (sim_close): Ditto
3731 * device.c (device_tree_print_device): New. Prints the device
3732 tree in a format that is consistent with what can be parsed by the
3733 device tree load from file code.
3735 * psim.c (psim_create): Dump device tree if enabled. If nump
3736 selected, exit psim immediatly.
3738 Wed Jan 17 19:36:52 1996 Andrew Cagney <cagney@highland.com.au>
3740 * corefile-n.h (core_map_read_N): When mapping from an address to
3741 a device, do not subtract the devices base. The device its self
3742 can do this. Brings the behavour into line with OpenBoot.
3743 * corefile-n.h (core_map_write_N): Ditto
3744 * corefile.c (core_map_read_buffer): Ditto
3745 * corefile.c (core_map_write_buffer): Ditto
3747 * device_table.c (console_io_read_buffer_callback): Adjust to
3748 handle biased address.
3749 * device_table.c (console_io_write_buffer_callback): Ditto
3751 Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
3753 * device.c (attach_device_interrupt_edge): New. Interrupt model
3754 did not allow interrupts to be wired up as a general net (edges).
3755 Re-implement so that interrupt events can be passed to multiple
3756 controllers and interrupt controllers can further propogate
3759 * device.c (attach_device_interrupt_edge) : New, Ditto
3760 * device.c (detach_device_interrupt_edge) : New, Ditto

3762 * device.c (device_interrupt_event) : New, Ditto
3763 * device.c (device_interrupt_attach) : New, Ditto
3764 * device.c (device_interrupt_detach) : New, Ditto
3765 * device.c (device_child_interrupt_attach) : New, Ditto
3766 * device.c (device_child_interrupt_detach) : New, Ditto
3768 * device.c (device_attach_interrupt) : Delete old
3769 * device.c (device_detach_interrupt) : Delete old
3770 * device.c (device_interrupt) : Delete old
3771 * device.c (device_interrupt_ack) : Delete old
3773 * device_table.c (unimp_*) : Update to match
3775 * device_table.c (icu_io_write_buffer_callback) : Update to use
3777 * device_table.c (icu_interrupt_event_callback) : Ditto
3779 Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
3781 * device.c (external_to_device) : New function that provides a
3782 standard mapping between a devices internal representation (a
3783 pointer) and its external (or what is passed to a client)
3784 representation (a phandle). Implement using the cap object
3785 attached to the root node.
3787 * device.c (device_to_external) : Ditto
3788 * device.c (external_to_device_instance) : Ditto but for ihandle
3789 and device instance.
3790 * device.c (device_instance_to_external) : Ditto
3792 * Makefile (device.o): Add dependency on cap.
3794 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
3795 needing to translate between internal and external representations
3796 changed to use the external_to_device et.al. device operations.
3797 * emul_chirp.c (chirp_emul_*) : Ditto
3799 * Makefile (emul_chirp.o): Remove dependency on cap
3801 Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
3803 * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
3804 on OpenBoot note section.
3806 Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
3808 * emul_generic.c (emul_write_buffer): Use vm faulting byte
3809 read/write calls for buffer transfers. This will cause a fault to
3810 occure if the transfer fails. CHRP catches the fault while the
3811 others suffer the consequences.
3812 (emul_read_buffer): Ditto.
3813 (emul_write_word): Ditto.
3814 (emul_read_word): Ditto.
3815 (emul_read_string): Ditto.
3817 Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
3819 * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
3820 emul_generic (emul_blr_instruction): Use a real blr instruction to

3823 * emul_chirp.c (services): Add all OpenBoot services to table.
3825 * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
3826 (emul_chirp_create) : Use names instead of numbers for
3827 instructions being stored in memory.
3829 Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
3831 * Makefile.in (maintainer-clean): Remove .log, core and *.core
