|
|
1999-04-02 Keith Seitz <keiths@cygnus.com>
|
|
|
|
* sim_calls.c (POLL_QUIT_INTERVAL): Define. Used to tweak
|
|
the frequency at which the poll_quit callback is called.
|
|
(poll_quit_count): New global.
|
|
(sim_io_poll_quit): Only call the poll_quit callback
|
|
after the specified POLL_QUIT_INTERVAL.
|
|
|
|
1999-02-22 Jim Lemke <jlemke@cygnus.com>
|
|
|
|
* dc-complex: Force expansion on all bits of field BO.
|
|
Previously, the least-significant (prediction) bit was ignored.
|
|
* ppc-instructions (conditional branches): Implement mpc860c0 option.
|
|
* igen.c (gen_semantics_[ch]): Setup for mpc860c0 option.
|
|
* psim.c (is_num, psim_options): Added parsing for mpc860c0 option.
|
|
* interrupts.h: Added "mpc860c0_instruction_program_interrupt".
|
|
* 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.
|
|
ppc-instructions(the four branch insn groups): detect problematic br's.
|
|
psim.c(is_num - added, psim_options): Parse and init new option.
|
|
These changes are currently under #ifdef WITH_OPTION_MPC860C0.
|
|
|
|

|
|
|
|
* sim_callbacks.h, sim_calls.c (sim_io_poll_quit): New function,
|
|
poll the external environment.
|
|
|
|
1998-11-19 Michael Meissner <meissner@cygnus.com>
|
|
|
|
* ppc-instructions (is_{NaN,inf}): Use unsigned64 to get the
|
|
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.
|
|
|

|
|
|
|
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

|
now defined in ../common/aclocal.m4, and the double definition causes

|
problems with AC_SUBST of EXEEXT.

* gen-icache.c: Generalize code handling XXX_is_NNN so that it
|
|
works for normal and boolean table entries.
|
|
|
|
* psim.c (psim_write_memory): last_cpu == -1 or nr_cpus is now
|
|
valid. Handle this just like *_{read,write}_register now handles

|
|

|
|
|
|
* When performance monitoring is disabled, it is still possible to
|

ticks recorded by the event queue.
|
|
|
|
* psim.c (psim_write_register, psim_read_register): Force the cpu
|
|

|
|
|
|
* The code to allow an event queue to be updated during a signal
|
|
was missing. For main.c, a cntrl-c simulation termination wasn't
|
|
handled cleanly.
|
|
|
|
* The simulation would not correctly restart if an event requested
|
|
that the simulation be halted.
|
|
|
|
* psim.c (psim_options): Add hack to -i option to optionally
|
|
include a level vis -i2.
|
|
(psim_usage): Document.

(event_queue_init): Start the event queue out with processing
|
|
false.
|
|
(event_queue_tick): Check that processing isn't still being

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

* ppc-instructions: Change all `RA == 0' to RA_is_0.
|
|

Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
|
|
|
|
* hw_trace.c (hw_trace_init_data): Delete. The trace options need
|
|
to be initialized independant of the rest of the simulation
|
|
initalization. Otherwize a trace option explictly set from gdb
|
|
could be overridden by hw_trace.
|
|
|
|
* psim.c (psim_options): Clarify reason why the trace ioctl occures.
|
|
|
|
* FIXME: The trace code is too scattered - hw_trace.c, psim.c,
|
|
debug.c. It could be much simpler.
|
|
|
|
Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
|
|
|

|
|
string array - use the first entry for the initial file image.

Wed Jan 22 09:38:33 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
|
|
|
|
* For expressions like (RA == 0) that are entered in to the cache
|
|
as RA_is_0. If possible generate the result of the expression so
|
|
that the compiler gets a better chance of eliminating dead
|
|
branches.
|
|
|
|
* gen-icache.c (print_icache_extraction): For a cache entry of
|
|
the form <name>_is_<const> where it is a boolean field, generate
|
|
the result of the expression instead of the expression its self.
|
|
(print_icache_body): Remove code that was looking for *_is_0 and
|
|
then generating corresponding definitions.
|
|
|
|
* gen-icache.c (print_icache_struct): If there is no cache, do not
|
|
output expressions in idecode.h file.

|
|
|
Wed Jan 22 12:24:52 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>
|
|
|
|
* The code that put values in and extracted values from the cache
|
|
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

when the cache entry is being used.
|
|
* gen-icache.c: Update.

|
|
|
|
* gen-icache.h, gen-icache.c (print_icache_body): Make the three
|
|
different types of cache code - put into cache, extract from
|
|
cache, no cache - an explicit argument to print_icache_body.

|
|
|
|

|
|
cache.
|
|
|
|
* configure.in (enable-sim-icache): Clarify description. Make
|

|
|
|
|
* The cap object was retaining a reference to the instance of a
|
|
device after it was deleted. Instead add and remove cap's from the
|
|
cap db as they are created and deleted. This ensuring that a
|
|
capibility is only used during the lifetime of the corresponding
|
|
object.
|
|

|
|
|
|
* The memory "claim" and "release" methods take an address and
|

|
|
things. Extract all information from the device tree.

|
|
|
|
* 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
|

|
|
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.

|
|
|
|
* 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.

|
|
|
|
* 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 (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

|
|
|
|
* 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.
