e7c7c92184 Tracing now works for upto 4 threads. Easy change to get it to work for more, but I don't have any test handy to test it.
cpu/trace/reader/m5_reader.cc:
    Add thread num.
cpu/trace/trace_cpu.cc:
    Increase thread count to 4, might want to make this a parameter (but it only really costs us storage).

53dde8579b Renamed OpClass enum members: they all end in 'Op' now.
Got rid of two inconsistent sets of strings that corresponded
to this enum, and replaced with a single set that clearly
matches the enum names.

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.

27a6e8258d Add a level of indirection to the register accessors used in
instruction execute methods.  Register i now means the instruction's
i'th src (or dest) operand, not architectural register i.  Current
models that use the architectural reg index can look that up easily
in the instruction object.  Future models that do register renaming
should find this much simpler to deal with.

    Generate register accessors with an extra level of indirection.
cpu/simple_cpu/simple_cpu.hh:

4c55d26e66 Replace explicit xc->misspeculating() tests in execute() methods
with an IsNonSpeculative flag.
No effect on results of non-full-system or SimpleCPU.
Very small impact on full-system FullCPU runs since old wrong-path
call_pal insts used to change the PC, where now they're treated
as no-ops.

arch/alpha/isa_desc:
    Get rid of xc->misspeculating() checks, use IsNonSpeculative flag instead.

    Add IsNonSpeculative flag and isNonSpeculative() method to test it.

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.

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:

    numInsts is now a real Scalar stat, not a Formula

    add new stat for tick frequency

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

    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.

b6ff600bca Add support for "serializing" instructions that flush
execution pipeline (Alpha trapb & excb).

Add support for write memory barriers (mostly impacts
store buffer).

Add StaticInst flag to indicate memory barriers, though
this is not modeled in the pipeline yet.

arch/alpha/isa_desc:
    Implement trapb, excb, mb, and wmb as insts with
    no execution effect (empty execute() function) but
    with flags that indicate their side effects.

    Also make sure every instruction that needs to go to
    the execute stage has a real opClass value, since we
    are now using No_OpClass to signal insts that can get
    dropped at dispatch.

    StaticInst::branchTarget() is now a const method.
cpu/static_inst.hh:
    Add flags to indicate serializing insts (trapb, excb) and
    memory and write barriers.

    Also declare some StaticInst methods as const methods.
