Reorganization/renaming of CPUExecContext. Now it is called SimpleThread in order to clear up the confusion due to the many ExecContexts. It also derives from a common ThreadState object, which holds various state common to threads across CPU models.
Following with the previous check-in, ExecContext now refers only to the interface provided to the ISA in order to access CPU state. ThreadContext refers to the interface provided to all objects outside the CPU in order to access thread state. SimpleThread provides all thread state and the interface to access it, and is suitable for simple execution models such as the SimpleCPU. src/SConscript: Include thread state file. src/arch/alpha/ev5.cc: src/cpu/checker/cpu.cc: src/cpu/checker/cpu.hh: src/cpu/checker/thread_context.hh: src/cpu/memtest/memtest.cc: src/cpu/memtest/memtest.hh: src/cpu/o3/cpu.cc: src/cpu/ozone/cpu_impl.hh: src/cpu/simple/atomic.cc: src/cpu/simple/base.cc: src/cpu/simple/base.hh: src/cpu/simple/timing.cc: Rename CPUExecContext to SimpleThread. src/cpu/base_dyn_inst.hh: Make thread member variables protected.. src/cpu/o3/alpha_cpu.hh: src/cpu/o3/cpu.hh: Make various members of ThreadState protected. src/cpu/o3/alpha_cpu_impl.hh: Push generation of TranslatingPort into the CPU itself.
