Mike Frysinger af9f7da78b sim: add sim_complete_command stubs for non-common-using ports 
For the ports that don't use the common/ subdir, we need to add stub funcs
to them to avoid build failures with gdb and command completion.  These do
not implement the actual completion functionality ... any port that wants
that can either convert to the common/ subdir, or fill out the function on
their own time.

the frequency at which the poll_quit callback is called.

* psim.c (is_num, psim_options): Added parsing for mpc860c0 option.

* 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.
* ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
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]).
interrupts.[ch](mpc860c0_instruction_program_interrupt): added.

fractional type, so that quiet NaN's aren't treated like
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>
* emul_netbsd.c (do_open): fix order-of-evaluation problem.

sys/mount.h. It conflicts on Linux when gnu libc2 is used.
Tue May 12 12:10:33 PDT 1998 James Ingham <jingham@leda.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

determine the simulation speed by looking at the number of elapsed
ticks recorded by the event queue.
* psim.c (psim_write_register, psim_read_register): Force the cpu
to zero when it is either of `-1' or `nr_cpus'. In both cases the

per second.
Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

include a level vis -i2.

reworked idecode.
Wed Jan 29 12:14:19 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

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

the form <name>_is_<const> where it is a boolean field, generate
the result of the expression instead of the expression its self.

was too compilicated. The cache table did not allow values to be
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.
* gen-icache.c: Update.
* ld-cache.h, ld-cache.c: Change field names so that their meaning
is more obvious. old_name->field_name, new_name->derived_name.

Wed Jan 17 19:51:56 1996 Andrew Cagney <cagney@highland.com.au>
* psim.c(psim_options): Parse the psim options, installing their
value in the device tree. Options are now first entered into a
device tree and then extracted out again when needed. This allows
greater flexability in configuration.
* psim.c (psim_tree): Returns a basic device tree ready for
parsing by psim_options.
* psim.c (psim_usage): New. Give usage to varing levels of detail
according to the verbosity. In turn output device and trace
usage.

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

handle biased address.

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 (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

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.

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>
