cfb6f8fd01 Added copy instructions to the ISA. Well it didn't break anything yet...
arch/alpha/isa_desc:
    Add copy_load and copy_store insts (ldf and stf respectively)
cpu/simple_cpu/simple_cpu.hh:
    Add copy functions to SimpleCPU as well

6f5e104fc5 Make SW prefetch flag a parameter again, and add code to make
it actually do something on FullCPU.  Still disabled, as it
causes detailed-boot to hang when you turn it on.

arch/alpha/isa_desc:
    Add EAComp and MemAcc pseudo-instructions to prefetch StaticInst.
cpu/simple_cpu/simple_cpu.hh:
    Changed prefetch() return type from Fault to void.

6a306d4caf add in an init() callback for CPU's so that no stats are accessed prior to the end of the build process. (Done by doing the registerExecContext() calling sequence in the init() process rather than the create() process).

548b4a1cb0 Change "Foo& foo" declarations to "Foo &foo".
This primarily to be internally consistent (sometimes we used one,
sometimes the other, even within the same line of code!).

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

921b1ee87b Add the ability to track stats in user defined sets of function calls. code can be generated via the base/instrum_codegen.pl script to easily change the functions being tracked. the only thing the user needs to do is add code in tru64System to change how the callerMap is populated.
command line:

m5.* <config file> <args> --server.system:bin=true to track function calls in the server
m5.* <config file> <args> --client.system:bin=true to track function calls in the client

base/statistics.cc:
    make an adjustment to the way stats are printed for FS_MEASURE

    add a name() virtual function to GenBin.  add a debug printf for activate().
    add amake MainBin the default bin when FS_MEASURE.

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:
    Don't need initStatus() any more.
cpu/simple_cpu/simple_cpu.cc:
    Move execCtxStatusChg() from header to .cc file.
    No longer need specialized version of registerExecContexts to schedule TickEvent.

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
of ExecContexts with System/Process object factored out so we can create two CPUs
but only register one of them at a time.  Also worked at making behavior and naming
in System and Process objects more consistent.
