1d545281b9 Significant changes to ISA description to completely factor
out CPU model.  ISA description now generates multiple
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.
cpu/simple_cpu/simple_cpu.hh:
    SimpleCPUExecContext typedef no longer needed.
    Add forward declaration of Process.
cpu/static_inst.hh:
    SimpleCPUExecContext and FullCPUExecContext typedefs no longer needed.
    Make eaCompInst() and memAccInst() return const refs.

a4d7bb113a Make a new stat type of Value which is a scalar stat that
proxies for a real C/C++ scalar value or scalar functor.
This replaces the scalar() and functor() terms that were
previously used in formulas.  This helps when dumping
statistics because the formulas are not supposed to change.

cpu/base_cpu.cc:
    Add a number of cycles stat to the cpu object that tracks the
    number of cycles that the cpu has executed.  This starts to pave
    the way for cpu cycles being different from event ticks.
cpu/base_cpu.hh:
    provide a functor for calculating all simulated instructions
    of all CPUs and a virtual function for determining that number.
    To deal with the change from functor() to Value::functor()
cpu/simple_cpu/simple_cpu.cc:
    simTicks -> numCycles
    numInsts is now a real Scalar stat, not a Formula
cpu/simple_cpu/simple_cpu.hh:
    numInsts is now a real Scalar stat, not a Formula
    count all instructions
sim/stat_control.cc:
    simInsts, simTicks, hostMemory, and hostSeconds are no
    longer Statistics::Formula but rather Statistics::Value
    add new stat for tick frequency
sim/stats.hh:
    don't need everything to be extern.
test/Makefile:
    Make stuff work a tad bit better
test/stattest.cc:
    test out Statistics::Value

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.

    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.

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 uint64_t for init_param param.
test/paramtest.cc:

1d7c11af7d Instead of keeping track of the fraction of time that we're
idle, keep track of the fraction of time we're not idle.  This
works better because the default processor state is idle, and
the default stat value is 0.
Keep the stat as idleFraction which is a formula that is equal
to 1 - notIdleFraction

template functions to support syscalls with slightly different constants
or interface structs.

91cb532f9f Make FullCPU schedule its TickEvent when one of its contexts becomes active.
This fixes detailed-mpboot, which was broken as of my last change.
Also clean up some of the ExecContext status initialization.

cpu/base_cpu.hh:
    CPU::execCtxStatusChg() now takes thread_num as an arg so the CPU knows
    which execContext had the status change.
    BaseCPU::registerExecContexts() no longer needs to be virtual.
cpu/exec_context.cc:
    Initialize _status directly... don't use setStatus() as this will notify the CPU
    of the change before it is ready.
    CPU::execCtxStatusChg() now takes thread_num as an arg so the CPU knows
    which execContext had the status change.
cpu/exec_context.hh:

f5da73b688 Initial support for CPU switching. New SamplingCPU object encompasses a set
of CPUs that get switched round-robin (though currently we're only shooting for
two CPUs and one switch event, and even that doesn't quite work yet).  Registration

but only register one of them at a time.  Also worked at making behavior and naming
in System and Process objects more consistent.
