address calculation and memory access portions separately.
Not currently used by any CPU models, but Kevin says he needs this.
Also clean up handling of execution tracing for memory accesses
(move it all into isa_desc and out of CPU models).
Got rid of some ancient unused code too.
arch/alpha/isa_desc:
Add execute() methods to EAComp and MemAcc portions of memory
access instructions, to allow CPU models to execute the effective
address calculation and memory access portions separately.
Requires the execution context to remember the effective address
across the two invocations. Added setEA() and getEA() methods to
execution context to support this. A model that does not use the
split execution model can panic if these methods are called.
Also added hook to call traceData->setAddr() after EA computation
on any load or store operation.
arch/isa_parser.py:
Call traceData->setData() on memory writes (stores).
cpu/simple_cpu/simple_cpu.cc:
Get rid of unused code.
cpu/simple_cpu/simple_cpu.hh:
Add (non-functional) setEA() and getEA() methods for new
split memory access execution support.
