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.

output source files to (in theory) reduce compilation time.
arch/alpha/isa_desc:
Update for parser changes. Move most constructors
out of class declarations (which are now in decoder.hh)
and into decoder.cc. Move all execute() methods into
exec output.
arch/isa_parser.py:
Significant changes to make ISA description completely
independent of CPU model, and isolate model-dependent parts
of parser into one little class (CpuModel). Also split up code
output into multiple files (a header, a main source file, and
per-cpu execute() method files).
Noticeable changes to language as a result. See updated Doxygen
documentation.
