every time an event is removed from the queue.
(update_time_from_event): Delete assertion that a negative

the frequency at which the poll_quit callback is called.
(poll_quit_count): New global.

after the specified POLL_QUIT_INTERVAL.
1999-02-22 Jim Lemke <jlemke@cygnus.com>

* interrupts.c (program_interrupt): Added handling for above interrupt.
1999-02-01 Jim Blandy <jimb@zwingli.cygnus.com>
Make the simulator compatible with the MPC750. It would be nicer
to make this a real multi-sim, but that's more work than we have
time for.
* emul_generic.c (emul_add_tree_options): Only require strict
alignment if it was explicitly requested at configuration time.
Don't make it the default for little-endian machines.

MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
THRM2, THRM3): Plop in the MPC750 SPR registers.
(DABR): This is weird. This was HID5, but the PPC spec says this
should be DABR; why did some random processor use it for something
else? The HID5 entry dates back to the original checkin of the
simulator code in 1995, so remove it.
* sim_calls.c (register_names): Delete this; since the user can
now change GDB's list of register names dynamically, we can't
pretend there's a static mapping here.
(sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
function to get the register name. That ought to be accurate.
However, we're changing a compile-time dependency (using the
REGISTER_NAMES macro) into a link- and run-time dependency
(calling REGISTER_NAME, which happens to be a function call on the
PPC).
1999-01-22 Jim Lemke <jlemke@cygnus.com>
* igen.c(gen_semantics_[ch]): setup/use of new option
(-o mpc860c0[=n]).

Infinities.
Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
* table.c (table_open): For cygwin hosts, we need to use the
return value from the read routine as the number of bytes to
process. This apparently is due to text-mode vs binary-mode. If
the mounts are done text-mode, then the size returnedby fstat()
may be different than the number of bytes "read" in text mode.
Sun Oct 4 00:50:47 1998 Felix Lee <flee@cygnus.com>

* Makefile.in: The run target depended on a target psim$(EXEEXT),
but there was no such target, only plain psim. So I changed the
run target to depend on psim.
Sat May 2 01:10:12 1998 Stu Grossman <grossman@babylon-5.cygnus.com>
* aclocal.m4: Remove defs of AM_EXEEXT and AM_CYGWIN32. These are

* FIXME: The trace code is too scattered - hw_trace.c, psim.c,
debug.c. It could be much simpler.

computed from cache entries. #defines could only be used when a
cache was present, remove the restriction.
* ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
scratch variable is defined when a cache entry is beinf
filled. Change the definition of a COMPUTE variable to be defined
when the cache entry is being used.

* psim.c (psim_options): Add `o' option - openboot tree entry.
* psim.c (psim_options): Add `h'/`H' options - more help.
* debug.c (trace_usage): Add more detailed help.
* device.c (device_usage): New. Output help including a list of
the devices currently available in the device table.
* device_table.c: Add usage operator to each device.
* corefile.c (core_create, core_device_create): Adjust so that the
core device is created earlier for psim_tree(). Core can later be
created from it.
* psim.c (psim_create): Update to handle above way of creating
things. Extract all information from the device tree.
* device_tree.c (trace_*): New device node, its properties are
used to set the value of the trace options. Init this device (in
psim_options) when ever the options are updated.
Wed Jan 17 19:46:07 1996 Andrew Cagney <cagney@highland.com.au>
* debug.h: Add trace_print_info, trace_print_device_tree and
trace_dump_device_tree. The first is a replacement for the
variable `print_info' found in main.c and sim_calls.c. The latter
two enable the dumping of the entire device tree.
* debug.c: Add to trace_description table.
* main.c (main): Use above trace instead of local variable
* sim_calls.c (sim_close): Ditto
* device.c (device_tree_print_device): New. Prints the device
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.
