Also various changes to make the CPU model less ISA dependent, which includes moving the code that checks for interrupts up to the ISA level, moving code that zeroes the zero registers up to the ISA level, and removing opcode and ra from the regfile.
arch/alpha/alpha_memory.cc:
The regfile has been changed so it no longer has the opcode and ra. Instead the xc holds the actual instruction, and from there the opcode and ra can be obtained with OPCODE() and RA().
arch/alpha/ev5.cc:
Moved code that once existed within simpleCPU to ev5, and templatized it.
This way the CPU models can call processInterrupts and the ISA specific interrupt handling is left to the ISA's code.
Also moved ISA specific zero registers from simpleCPU to here.
arch/alpha/ev5.hh:
Added macros for obtaining the opcode and ra from the instruction itself, as there is no longer opcode or ra in the regfile.
arch/alpha/isa_desc:
Added in declarations for the FastCPU model.
arch/alpha/isa_traits.hh:
Removed opcode and ra from the regfile. The xc now holds the actual instruction, and the opcode and ra can be obtained through it.
Also added the declaration for the templated zeroRegisters() function, which will set the zero registers to 0.
arch/isa_parser.py:
Added in FastCPUExecContext so it will generate code for the FastCPU model as well.
cpu/exec_context.cc:
Added in a more generic trap function so "ev5_trap" doesn't need to be called. It currently still calls the old method, with plans for making this ISA dependent in the future.
cpu/exec_context.hh:
Exec context now has the instruction within it. Also added methods for exec context to read an instruction from memory, return the current instruction, and set the instruction if needed.
Also has declaration for more generic trap() function.
cpu/simple_cpu/simple_cpu.cc:
Removed references to opcode and ra, and instead sets the xc's instruction with the fetched instruction.
cpu/static_inst.hh:
Added declaration for execute() using FastCPUExecContext.

Do a better job of factoring out CPU model. (Still not perfect though.)
Pull execute() methods out of class declarations into separate section

execution context into a single model-dependent class (SimpleCPU itself
for SimpleCPU, DynInst for FullCPU).

base/statistics.hh:
major changes to the statistics package again
lots of code was factored out of statistics.hh into several
separate files in base/stats/ (this will continue)
There are now two Stat package types Result and Counter that
are specified to allow the user to keep the counted type
separate from the result type. They are currently both doubles
but that's an experiment. There is no more per stat ability to
set the type. Statistics::Counter is not the same as Counter!
Implement a visitor for statistics output so that new output
types can be implemented independently from the stats package
itself.
Add a unique id to each stat so that it can be used to keep
track of stats more simply. This number can also be used in
debugging problems with stats.
Tweak the bucket size stuff a bit to make it work better.

configuration unnecessarily awkward. Biggest changes are:
- External and internal object names now match in all cases. The
macros still allow them to be different; the only reason I didn't
get rid of that is that the macros themselves should be going away
soon. In the few conflicting cases, I sometimes renamed the C++ object
and sometimes renamed the config object. The latter sets of substitions
are:
s/BaseBus/Bus/;
s/MemoryObject/FunctionalMemory/;
s/MemoryControl/MemoryController/;
s/FUPool/FuncUnitPool/;
- SamplingCPU is temporarily broken... we need to change the model

really awkward.
