    Just to make sure, remove the new copy instructions until everything works.

c79deda8cd Fix handling of rpcc in full-system mode.
arch/alpha/ev5.cc:
    Handle writing IPR_CC and IPR_CC_CTL slightly more intelligently.
    (Very slightly).
arch/alpha/isa_desc:
    Upper half of rpcc result comes from value written
    to IPR_CC, not actual cycle counter.

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.

510eef0fa0 Modify handling of serialize:dir parameter to make it more useful.

    of file name.

    Make serialize:dir parameter actually set checkpoint directory name
    instead of directory in which checkpoint directory is created.  If
    the value contains a '%', the curTick value is sprintf'd into the
    format to create the directory name.  The default is backwards compatible
    with the old fixed name ("m5.%012d").

777c1ebfab Stats & serialization tweaks & cleanup. Unserializing from
a checkpoint now gives identical results to running from scratch
and doing at switchover at the same cycle!
- CPUs start at cycle 0 again, not cycle 1.
- curTick is now serialized & unserialized.
- Stats get reset in main (before event loop).  Since this is done
after curTick is unserialized, simTicks gets set correctly for
running from a checkpoint.
- Simplify serialization to happen in a single pass.

7976794aad Restructuring of LiveProcess etc. to support multiple emulated OS syscall
interfaces, and specific support for Alpha Linux.  Split syscall emulation
functions into several groups, based on whether they depend on the specific
OS and/or architecture (and all combinations of above), including the use of
template functions to support syscalls with slightly different constants
or interface structs.

arch/alpha/alpha_tru64_process.cc:
    Incorporate full Tru64 object definition here, including structure and constant definitions.

    and the second is a period.  The delay tells the simulator to wait the
    specified number of nanoseconds before triggering the event, the period
    tells the simulator to repeat the event with a specified frequency

    Don't AutoDelete an event if it is scheduled since the process()
    function could potentially schedule the event again.
sim/main.cc:
    DumpStatsEvent is now Statistics::SetupEvent(Dump, curTick)
sim/serialize.cc:
    Change the serialize event so that it's possible to cause the
    event to repeat.  Also make the priority such that the event
    happens just before the simulator would exit if both events
    were scheduled for the same cycle.

    get rid of the serializeFilename variable and provide a CheckpointFile()
    function.  This function takes a basename that is set in the
    configuration, and appends the current cycle to the name so that
    multiple checkpoints can be dumped from the same simulation.

    Also, don't exit the simulation when a checkpoint file is dumped.
sim/serialize.hh:
    serializeFilename -> CheckpointFile()
    SetupCheckpoint function to tell the simulator to prepare

sim/sim_events.cc:

    stats context in stat_context.cc

    DumpStatsEvent stuff gets move to sim_stats.(cc|hh)
sim/universe.cc:
    Provide some simple functions for converting times into
    ticks.  These use floating point math to get as close as
    possible to the real values.  Multipliers are set up ahead
    of time

    unserialize() now takes a Checkpoint* instead of an IniFile*.

sim/serialize.cc:

    Define Checkpoint object to encapsulate everything you need to know

    unserialize() now takes a Checkpoint* instead of an IniFile*.
