Constructor takes a bool to signify that it is either a cpu_request or not a cpu_request.
When accedding variables of a cpu_request it asserts that it is a cpu_request.
It also asserts that a value being read has been written at some point in time prior (not gaurnteeing it is up to date, but it was at least written before read).
There is also a isCpuReq() function to determine if this is a cpu_request. It should be called before accesing a cpu_request only variable.

The major change is renaming the old ExecContext to CPUExecContext, and creating two new classes, ExecContext (an abstract class), and ProxyExecContext (a templated class that derives from ExecContext).
Code outside of the CPU continues to use ExecContext as normal (other than not being able to access variables within the XC). The CPU uses the CPUExecContext, or however else it stores its own state. It then creates a ProxyExecContext, templated on the class used to hold its state. This proxy is passed to any code outside of the CPU that needs to access the XC. This allows code outside of the CPU to use the ExecContext interface to access any state needed, without knowledge of how that state is laid out.
Note that these changes will not compile without the accompanying revision to automatically rename the shadow registers.

into zamp.eecs.umich.edu:/z/ktlim2/m5-shadowregs
arch/alpha/ev5.cc:
Remove intr_post, it is no longer used.

Hand merge.

The shadow registers are folded into the normal integer registers to ease renaming indexing.
Include the removed Opcdec class of instructions for faulting when a pal mode only instruction is decoded in non-pal mode.
arch/alpha/ev5.cc:
Changes to automatically map the shadow registers if the instruction is in PAL mode.
arch/alpha/isa/branch.isa:
arch/alpha/isa/decoder.isa:
arch/alpha/isa/fp.isa:
arch/alpha/isa/int.isa:
arch/alpha/isa/mem.isa:
arch/alpha/isa/pal.isa:
arch/alpha/isa/unimp.isa:
Changes for automatically using the shadow registers. Now instructions must decode based on an ExtMachInst, which is a MachInst with any decode context information concatenated onto the higher order bits.
arch/alpha/isa/main.isa:
Changes for automatically using the shadow registers. Now instructions must decode based on an ExtMachInst, which is a MachInst with any decode context information concatenated onto the higher order bits.
The decoder (for Alpha) uses the 32nd bit in order to determine if the machine is in PAL mode. If it is, then it refers to the reg_redir table to determine the true index of the register it is using.
Also include the opcdec instruction definition.
arch/alpha/isa_traits.hh:
Define ExtMachInst type that is used by the static inst in order to decode the instruction, given the context of being in pal mode or not.
Redefine the number of Int registers, splitting it into NumIntArchRegs (32) and NumIntRegs (32 + 8 shadow registers).
Change the dependence tags to reflect the integer registers include the 8 shadow registers.
Define function to make an ExtMachInst. Currently it is somewhat specific to Alpha; in the future it must be decided to make this more generic and possibly slower, or leave it specific to each architecture and ifdef it within the CPU.
arch/isa_parser.py:
Have static insts decode on the ExtMachInst.
base/remote_gdb.cc:
Support the automatic remapping of shadow registers. Remote GDB must now look at the PC being read in order to tell if it should use the normal register indices or the shadow register indices.
cpu/o3/regfile.hh:
Comment out the pal registers; they are now a part of the integer registers.
cpu/simple/cpu.cc:
Create an ExtMachInst to decode on, based on the normal MachInst and the PC of the instructoin.
cpu/static_inst.hh:
Change from MachInst to ExtMachInst to support shadow register renaming.

Ignoring returned latency for now.
Refactored loadSections in ObjectFile hierarchy.
base/loader/aout_object.cc:

base/loader/ecoff_object.cc:
base/loader/ecoff_object.hh:
base/loader/elf_object.cc:
base/loader/elf_object.hh:
base/loader/object_file.hh:
Have each section record a pointer to image data.
This allows us to move common loadSections code into ObjectFile.
base/loader/object_file.cc:
Have each section record a pointer to image data.
This allows us to move common loadSections code into ObjectFile.
Also explicitly load BSS now since we need to allocate the
translations for it in syscall emulation.
cpu/base.hh:
Don't need memPort (just pass port in to ExecContext constructor).
cpu/exec_context.cc:
cpu/exec_context.hh:
mem/port.cc:
mem/translating_port.cc:
mem/translating_port.hh:
Pass syscall emulation Port into constructor instead of
getting it from BaseCPU.
cpu/simple/cpu.cc:
Explicitly choose one of three timing models.
Statically allocate request and packet objects when possible.
Several more minor bug fixes.
Works for simple program with SIMPLE_CPU_MEM_IMMEDIATE model now.
Probably have memory leaks with SIMPLE_CPU_MEM_TIMING (if it works at all).
Pass syscall emulation Port into constructor instead of
getting it from BaseCPU.
cpu/simple/cpu.hh:
Explicitly choose one of three timing models.
Statically allocate request and packet objects when possible.
Pass syscall emulation Port into constructor instead of
getting it from BaseCPU.
mem/physical.cc:
Set packet result field.

memory access (I think because we're deallocating our one and only
CpuRequest object).
base/loader/aout_object.cc:
base/loader/ecoff_object.cc:
base/loader/elf_object.cc:
Add flag to force allocation of new pages on data writes.
cpu/simple/cpu.cc:
Several minor fixes.
Switch to atomic mode for now.
mem/physical.hh:
Don't copy the packet to the response event, just keep a reference
to the original.
mem/translating_port.cc:
mem/translating_port.hh:
Add parameter to writeBlobFunctional() to force allocation of
unallocated pages on writes.

arch/alpha/ev5.cc:
Commented out the intr_post function since it's not used. If this really -is- needed, it should be moved into the fault class.
arch/alpha/faults.cc:
arch/alpha/faults.hh:
Moved the fault invocation code into the fault class fully, and got rid of the need for isA.
cpu/exec_context.cc:
cpu/exec_context.hh:
Removed the trap function from the ExecContext. The faults will execute normally in full system mode, but always panic in syscall emulation mode.
cpu/ozone/cpu.hh:
cpu/simple/cpu.hh:
Changed the execution context executing a fault to a fault executing on the execution context.
sim/faults.cc:
If not in full system mode, trying to invoke a fault causes a panic.
sim/faults.hh:
Removed the isA function.
