255ac8372d Make stuff build on openbsd
arch/alpha/alpha_tru64_process.cc:
    So, I don't know why linux uses an off_t here.
    I'm also not sure why linux defines an off_t to be a long
    Let's just use long here since it works for linux, and that's
    what bsd does
base/inifile.cc:
    correct #include for OpenBSD
dev/disk_image.cc:
    the correct type for this is streampos

16021aa436 Fix previously committed call_pal fix... the main problem was in the
makefile, such that decoder.cc was not getting rebuilt.
Also add -fno-strict-aliasing to fix all the bizarre problems
I've been having with g++ 3.3.x.

arch/alpha/isa_desc:
    Fix compilation problems.  AlphaISA is a class now, not a namespace.

2cd5e980d2 Fixes for full-system call_pal instruction.
arch/alpha/alpha_memory.cc:
    Rename md_mode_type to mode_type.
arch/alpha/ev5.cc:
    simPalCheck() only gets called on correct path now, so
    there's no need to test misspeculating().
arch/alpha/isa_desc:
    Get privileged call_pall detection right this time (I hope).
    ExecContext::simPalCheck() and Annotate::Callpal() are now
    called only on non-speculative executions... this should fix
    the bogus pal-call stats we've been seeing (since these are
    incremented in simPalCheck()).
    Also check for invalid call_pall function codes.

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.
    This way we can wrap all of the functions inside the object, and not worry about namespace
    conflicts because no one outside this file will ever see it.

    LiveProcess is now effectively an abstract base class.
    New LiveProcess::create() function takes an object file and dynamically picks the
    appropriate subclass of LiveProcess to handle the syscall interface that file expects
    (currently Tru64 or Linux).

667cbb6690 Implement more m5 pseduo opcodes:
resetstats
dumpstats
dumpresetstats
m5checkpoint

Lots of cleanup of serialization and stats dumping/resetting to
work with these new instructions

arch/alpha/isa_desc:
    Implement more m5 pseduo opcodes:
    resetstats
    dumpstats
    dumpresetstats
    m5checkpoint

    All of these functions take two optional parameters, the first is a delay,
    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

sim/debug.cc:

    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.

    serializeFilename -> CheckpointFile()

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

4759c203c7 Remove all of the Tru64 specific stuff from the base System object
into its own Tru64System object.  Also remove the System builder
stuff and create a Tru64System builder.  This makes it much
