always update the cache_entries semantic and address fields.
* gen-idecode.c (print_idecode_switch_illegal): Include a break

hardware devices that are to be included in the build. Makes it

instead calling the idecode_run and idecode_run_until_stop
functions that gen-idecode.c is now creating.

match new interface.
* emul_bugapi.c (emul_bugapi_instruction_call): Adjust
corresponding call to ITRACE so that it still matches.

* gen-idecode.c (print_jump_until_stop_body): New function and

will cause igen to generate instruction decode functions that
include the corresponding semantic code.

tree in a format that is consistent with what can be parsed by the
device tree load from file code.
* psim.c (psim_create): Dump device tree if enabled. If nump
selected, exit psim immediatly.
Wed Jan 17 19:36:52 1996 Andrew Cagney <cagney@highland.com.au>
* corefile-n.h (core_map_read_N): When mapping from an address to
a device, do not subtract the devices base. The device its self
can do this. Brings the behavour into line with OpenBoot.
* corefile-n.h (core_map_write_N): Ditto
* corefile.c (core_map_read_buffer): Ditto
* corefile.c (core_map_write_buffer): Ditto
* device_table.c (console_io_read_buffer_callback): Adjust to
handle biased address.
* device_table.c (console_io_write_buffer_callback): Ditto
Wed Jan 17 18:36:09 1996 Andrew Cagney <cagney@highland.com.au>
* device.c (attach_device_interrupt_edge): New. Interrupt model
did not allow interrupts to be wired up as a general net (edges).
Re-implement so that interrupt events can be passed to multiple
controllers and interrupt controllers can further propogate
interrupt events.
* device.c (attach_device_interrupt_edge) : New, Ditto
* device.c (detach_device_interrupt_edge) : New, Ditto
* device.c (clean_device_interrupt_edges) : New, Ditto
* device.c (device_interrupt_event) : New, Ditto
* device.c (device_interrupt_attach) : New, Ditto
* device.c (device_interrupt_detach) : New, Ditto
* device.c (device_child_interrupt_attach) : New, Ditto
* device.c (device_child_interrupt_detach) : New, Ditto
* device.c (device_attach_interrupt) : Delete old
* device.c (device_detach_interrupt) : Delete old
* device.c (device_interrupt) : Delete old
* device.c (device_interrupt_ack) : Delete old
* device_table.c (unimp_*) : Update to match
* device_table.c (icu_io_write_buffer_callback) : Update to use
interface.
* device_table.c (icu_interrupt_event_callback) : Ditto
Wed Jan 17 18:18:40 1996 Andrew Cagney <cagney@highland.com.au>
* device.c (external_to_device) : New function that provides a
standard mapping between a devices internal representation (a
pointer) and its external (or what is passed to a client)
representation (a phandle). Implement using the cap object
attached to the root node.
* device.c (device_to_external) : Ditto
* device.c (external_to_device_instance) : Ditto but for ihandle
and device instance.
* device.c (device_instance_to_external) : Ditto
* Makefile (device.o): Add dependency on cap.
* emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
needing to translate between internal and external representations
changed to use the external_to_device et.al. device operations.
* emul_chirp.c (chirp_emul_*) : Ditto
* Makefile (emul_chirp.o): Remove dependency on cap
Sat Jan 6 10:13:26 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
* emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks
on OpenBoot note section.
Fri Jan 5 20:28:53 1996 Andrew Cagney <cagney@hignland.com.au>
* emul_generic.c (emul_write_buffer): Use vm faulting byte
read/write calls for buffer transfers. This will cause a fault to
occure if the transfer fails. CHRP catches the fault while the
others suffer the consequences.
(emul_read_buffer): Ditto.
(emul_write_word): Ditto.
(emul_read_word): Ditto.
(emul_read_string): Ditto.
Fri Jan 5 18:55:34 1996 Andrew Cagney <cagney@highland.com.au>
* emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call),
emul_generic (emul_blr_instruction): Use a real blr instruction to
return from a client service call.
* emul_chirp.c (services): Add all OpenBoot services to table.
* emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c
(emul_chirp_create) : Use names instead of numbers for
instructions being stored in memory.
Fri Jan 5 18:52:28 1996 Andrew Cagney <cagney@highland.com.au>
* Makefile.in (maintainer-clean): Remove .log, core and *.core
(From NetBSD) files.
Wed May 29 22:57:40 1996 Andrew Cagney <cagney@kremvax.highland.com.au>

ChangeLog.00
