Kevin Lim 30c516d51c Support for draining, and the new method of switching out. Now switching out happens after the pipeline has been drained, deferring the three way handshake to the normal drain mechanism. The calls of switchOut() and takeOverFrom() both take action immediately.

src/cpu/o3/alpha_cpu_builder.cc:

src/cpu/o3/iew.hh:

    Also limit the number of outstanding writebacks so the writeback buffer isn't overflowed.  The IQ must make sure with the IEW stage that it can issue instructions prior to issuing.
src/cpu/o3/iew_impl.hh:
    Include separate parameter for dispatch width.
    Also limit the number of outstanding writebacks so the writeback buffer isn't overflowed.
src/cpu/o3/inst_queue_impl.hh:
    IQ needs to check with the IEW to make sure it can issue instructions, and increments the IEW wb counter each time there is an outstanding instruction that will writeback.
src/cpu/o3/lsq_unit_impl.hh:
    Be sure to decrement the writeback counter if there's a squashed load that returned.
src/python/m5/objects/AlphaO3CPU.py:
    Change the parameters to include dispatch width, writeback width, and writeback depth.

Kevin Lim baba18ab92 Two updates that got combined into one ChangeSet accidentally. They're both pretty simple so they shouldn't cause any trouble.
First: Rename FullCPU and its variants in the o3 directory to O3CPU to differentiate from the old model, and also to specify it's an out of order model.

Second: Include build options for selecting the Checker to be used.  These options make sure if the Checker is being used there is a CPU that supports it also being compiled.

SConstruct:
    Add in option USE_CHECKER to allow for not compiling in checker code.  The checker is enabled through this option instead of through the CPU_MODELS list.  However it's still necessary to treat the Checker like a CPU model, so it is appended onto the CPU_MODELS list if enabled.
configs/test/test.py:
    Name change for DetailedCPU to DetailedO3CPU.  Also include option for max tick.
src/base/traceflags.py:
    Add in O3CPU trace flag.
src/cpu/SConscript:
    Rename AlphaFullCPU to AlphaO3CPU.

    Only include checker sources if they're necessary.  Also add a list of CPUs that support the Checker, and only allow the Checker to be compiled in if one of those CPUs are also being included.

    and m5.objects.

    (instead of clunky code injection method).
    Move main control from here into Python:
    - Separate initialization code and simulation loop
    into separate functions callable from Python.
    - Make Python interpreter invocation more pure (more
    like directly invoking interpreter).
    Add -i and -p flags (only options on binary itself;
    other options processed by Python).
    Import readline package when using interactive mode.
src/sim/sim_events.cc:
    SimExitEvent is now SimLoopExitEvent, and uses
    IsSimExit flag to terminate loop (instead of
    exiting simulator process).
src/sim/sim_events.hh:
    SimExitEvent is now SimLoopExitEvent, and uses
    IsSimExit flag to terminate loop (instead of

Kevin Lim 54d4220b00 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.
