a896960cbf FastCPU model added. It's very similar to the SimpleCPU, just without a lot of the stats tracking.
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.

7cab07268f Do a better job of factoring out CPU model in ISA description.
(Still not perfect though.)

arch/alpha/isa_desc:
    Do a better job of factoring out CPU model.  (Still not perfect though.)
    Pull execute() methods out of class declarations into separate section
    of file, allowing (1) easier replication for different CPU models and
    (2) a path to putting them all in a separate file.  Force all instruction
    execution context into a single model-dependent class (SimpleCPU itself
    for SimpleCPU, DynInst for FullCPU).
arch/isa_parser.py:
    Do a better job of factoring out CPU model.  (Still not perfect though.)
    Pull execute() methods out of class declarations into separate section
    of file, allowing (1) easier replication for different CPU models and
    (2) a path to putting them all in a separate file.
    Also restructure top level to allow parser to run under interactive
    interpreter session for easier debugging.
cpu/exec_context.hh:
    Add a few new methods to clean up isa_desc.
cpu/simple_cpu/simple_cpu.cc:
cpu/static_inst.hh:
    StaticInst::execute no longer takes a CPU and an ExecContext,
    just a unified FooCPUExecContext.
cpu/simple_cpu/simple_cpu.hh:
    Add methods to redirect calls to ExecContext so SimpleCPU
    can act as sole instruction execution context for itself.
    Typedef SimpleCPU to SimpleCPUExecContext.

24715f50ac add support for sticking generated files in the build directory
instead of with the source code.  This will hopefully be especially
useful when we're generating dozens of files when we flesh out the

    move the python output code to base/stats/puthon.(cc|hh)
    and reimplement it as a visitor.

    move the text output code to base/stats/text.(cc|hh) and
    reimplement it as a visitor.

    move the database stuff into base/stats/statdb.(cc|hh) and
    get rid of the class.  Put everything as globals in the
    Statistics::Database namespace.

    allocate unique ids for all stats.

    directly implement the check routine and get rid of the
    various dumping routines since they're now in separate files.

    make sure that no two stats have the same name

    clean up some loops
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.

    fixed VectorDist size bug
cpu/memtest/memtest.cc:
    Fix up for changes in stats package
    Don't use value() since it doesn't work with binning.  If you
    want a number as a stat, and to use it in the program itself,
    you really want two separate variables, one that's a stat,
    and one that's not.

d85b26d65a Minor enhancements to Python config stuff:

this is a special value, distinct from None.
- Initial, incomplete pass at regenerating C++ parameter code (declarations
and INIT_PARAM macros) from .odesc files.

0ef91aa905 Changes to config to allow everything (including 'children'
and 'type') to be specified via instance name and not just
config class.  Old code only did instance-name lookup for
SimObject parameters.  This feature makes life easier for
transitioning to the Python script-based config.

sim/builder.cc:
    Use ConfigNode::find to look for "type" parameter so it can
    be found if set under instance name (not config class).
sim/param.cc:
    Make Param<bool> accept "1" for true and "0" for false.

782fb42992 Basic cleanup pass to get rid of a few things that made the Python
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
of how this works in the .ini file.  Having it as a CPU proxy is
really awkward.

    Use unsigned instead of uint16_t for params.

    Use unsigned instead of uint64_t for init_param param.
