Gabe Black 7a6ed1b10b Power: Get rid of unused checkFpEnableFault. 
This function was brought in from another ISA and doesn't actually do anything
or get used.
 2010-08-23 16:14:23 -07:00
Gabe Black 943c171480 ISA: Get rid of old, unused utility functions cluttering up the ISAs. 2010-08-23 16:14:20 -07:00
Gabe Black 9581562e65 X86: Get rid of the flagless microop constructor. 
This will reduce clutter in the source and hopefully speed up compilation.
 2010-08-23 09:44:19 -07:00
Gabe Black f6182f948b X86: Make the TLB fault instead of panic when something is unmapped in SE mode. 
The fault object, if invoked, would then panic. This is a bit less direct, but
it means speculative execution won't panic the simulator.

Gabe Black 69fc2af006 X86: Add a .serializing directive that makes a macroop serializing. 
This directive really just tells the macroop to set IsSerializing and
IsSerializeAfter on its final microop.
 2010-08-23 09:44:19 -07:00
Gabe Black 5a1dbe4d99 X86: Consolidate extra microop flags into one parameter. 
This single parameter replaces the collection of bools that set up various
flavors of microops. A flag parameter also allows other flags to be set like
the serialize before/after flags, etc., without having to change the
constructor.

Branches are allowed to be the last instuction in an IT block. Before it was
assumed that they could not. So Branches in thumb2 were Uncond.

Min Kyu Jeong 5f91ec3f46 ARM/O3: store the result of the predicate evaluation in DynInst or Threadstate. 
THis allows the CPU to handle predicated-false instructions accordingly.
This particular patch makes loads that are predicated-false to be sent
straight to the commit stage directly, not waiting for return of the data
that was never requested since it was predicated-false.

This allows one two different OS requirements for the same ISA to be handled.
Some OSes are compiled for a virtual address and need to be loaded into physical
memory that starts at address 0, while other bare metal tools generate
images that start at address 0.

Steve Reinhardt 164a211f10 x86: minor checkpointing bug fixes 2010-08-17 05:20:39 -07:00
Steve Reinhardt f064aa3060 sim: revamp unserialization procedure 
Replace direct call to unserialize() on each SimObject with a pair of
calls for better control over initialization in both ckpt and non-ckpt
cases.

If restoring from a checkpoint, loadState(ckpt) is called on each
SimObject.  The default implementation simply calls unserialize() if
there is a corresponding checkpoint section, so we get backward
compatibility for existing objects.  However, objects can override
loadState() to get other behaviors, e.g., doing other programmed
initializations after unserialize(), or complaining if no checkpoint
section is found.  (Note that the default warning for a missing
checkpoint section is now gone.)

If not restoring from a checkpoint, we call the new initState() method
on each SimObject instead.  This provides a hook for state
initializations that are only required when *not* restoring from a
checkpoint.

Given this new framework, do some cleanup of LiveProcess subclasses
and X86System, which were (in some cases) emulating initState()
behavior in startup via a local flag or (in other cases) erroneously
doing initializations in startup() that clobbered state loaded earlier
by unserialize().

Do this by setting the delayed commit flag for all but the last microop.
 2010-06-02 12:58:12 -05:00
Gabe Black 67766cbf17 ARM: Fix the implementation of the VFP ldm and stm macroops. 
There were four bugs in these instructions. First, the loaded value was being
stored into a floating point register as floating point, changing the value as
it was transfered. Second, the meaning of the "up" bit had been reversed.
Third, the statically sized microop array wasn't bit enough for all possible
inputs. It's now dynamically sized and should always be big enough. Fourth,
the offset was stored as an unsigned 8 bit value. Negative offsets would look
like moderately large positive offsets.

Gabe Black 68f2908a70 ARM: Ignore/warn when CSSELR or CCSIDR are accessed. 
These registers provide information about the caches. Since we can't provide
that information, these will be harmlessly inert.
 2010-06-02 12:58:09 -05:00

Gabe Black 6a4ea7cca9 ARM: Implement the enterx and leavex instructions.

same as Thumb mode, but at least this will make it -look- like we're enter and
leaving it. The actual behavioral changes will be implemented in future
changes.

Gabe Black e658b6fed4 ARM: Add support for the clidr register.

to find out how many there really are when dealing with an arbitrary
hierarchy.

Gabe Black 896c7617c4 ARM: Decode the unimplemented data barrier CP15 accesses.

Barrier).
 2010-06-02 12:58:09 -05:00
Gabe Black af6b1667e9 ARM: Implement a stub of CPACR. 
This register controls access to the coprocessors. This doesn't actually
implement it, it allows writes which don't turn anything off. In other words,
it allows the simulated program to ask for what it already has.
 2010-06-02 12:58:09 -05:00

Gabe Black 221e0ac523 ARM: Warn about and ignore accesses to DCCISW. 
This register is supposed to "Clean and invalidate data or unified cache line
by set/way." Since there isn't a good way to do that, we'll just ignore these
and warn about it.

Gabe Black b6e2f5d33f ARM: Make sure ldm exception return writes back its base in the right mode. 
This change moves the writeback of load multiple instructions to the beginning
of the macroop. That way, the MicroLdrRetUop that changes the mode will
necessarily happen later, ensuring the writeback happens in the original mode.
The actual value in the base register if it also shows up in the register list
is undefined, so it's fine if it gets clobbered by one of the loads. For
stores where the base register is the lowest numbered in the register list,
the original value should be written back. That means stores can't write back
at the beginning, but the mode changing problem doesn't affect them so they
can continue to write back at the end.

Gabe Black 89060f1fd8 ARM: Rework how unrecognized/unimplemented instructions are handled. 
Instead of panic immediately when these instructions are executed, an
UndefinedInstruction fault is returned. In FS mode (not currently
implemented), this is the fault that should, to my knowledge, be triggered in
these situations and should be handled using the normal architected
mechanisms. In SE mode, the fault causes a panic when it's invoked that gives
the same information as the instruction did. When/if support for speculative
execution of ARM is supported, this will allow a mispeculated and unrecognized
and/or unimplemented instruction from causing a panic. Only once the
instruction is going to be committed will the fault be invoked, triggering the
panic.

Gabe Black 14d25fbad0 ARM: Don't rely on undefined behavior to get arithmetic right shift. 
Shifting to the right of a signed value when the MSB is one is technically
undefined behavior, even though in my experience it's done the "right thing"
and sign extended the value. This replaces the arithmetic right shift code in
ARM that uses that coincidence with some code that relies on bit math.

Gabe Black 05d880f7a1 ARM: Restrict the shift amount from a register to 8 bits.
