5cfff7d5bb First pass at a serializer object, may need to work on naming of object and functions:
Intended Use:
A SimObject will call the serializer when it needs the state to be serializable (i.e. switchCPUs, checkpoint, switch memory access model).  It will call the requestSeialization() function.
The Serializer will signal all the objects in its list to drain their state via the SimObject method drain().  Drain() has a default implementation to just signal done.
When each object is drained it will signal the Serializer that it has drained via the signalDrained() function.
The Serializer will collect these signals, when all have drained it will signal the initial requestor via serializationComplete() method in the SimObject.
Once that object is done, it will signal the Serializer to resumeExecution().
The Serializer will signal all the objects in its list to resume via the resume() method on the SimObject.

SConscript:
    Add serializer object to build list
sim/sim_object.cc:
    Add default behavior for drain (just signal finished, must be overided if you really must drain something)
sim/sim_object.hh:
    Add functions for serializer

80dee53b04 Fixes for Paired-Single FP Compare Operations...
Now all the variations of FP should be implemented correctly in the decoder.
The new formats and functions supporting these functions need to be implemented for
some of the FP stuff but for the most part things are looking like their "supposed to"...

c552b06a8c Support for FP Paired Single Operations
Auxiliary Functions and Formats for FP in general

arch/mips/isa/decoder.isa:
    ISA Parser doesnt accept operands of different types in one instruction so fix this for unorderedFP functions...
    Add basic support for Paired Singled (PS) FP ops which happen to be part of the MIPS 32-ASE but turned out to
    be included in the MIPS32ISA manual... The PS instructions allow SIMD in a pipeline...
arch/mips/isa/formats/fp.isa:
    Add some more Formats for FP operation. I will add some auxiliary code through these formats
    to alleviate code redundancy in the decoder.isa
arch/mips/isa/operands.isa:
    Add operands for Paired Singles Ops
arch/mips/isa_traits.cc:
    removed convert&round function and replace with fpConvert.
    The whole "rounding mode" stuff is something that should be considered for full-system mode...

    Also added skeletons for the unorderedFP,truncFP,and condition code funcs.
arch/mips/isa_traits.hh:

arch/mips/types.hh:

6375b7aca9 revamping code to appropriately handle FP condition code and conversion ops.
There still needs to be a work around to handle the paired singles operations ...

arch/mips/isa/decoder.isa:
    More revamping of the floating point ops in decoder.isa. Change all of the
    "convert and round" functions to fpConvert. Also, the utility functions
    roundFP, truncFP, and unorderedFP are in place everywhere. Things
    have been set up to appropriately use the FP condition codes in the decoder.isa
    The fp.isa format file and the isa_traits.cc file now needed to be updated
    to implement the appropriate "backend" operations/functionality...
arch/mips/isa_traits.hh:
    Remove convert & round functions
    Add roundFP, truncFP,unorderedFP, and the get/setFPconditionCode
    functions

6dc3b2fa39 make ide disk work for newmem
SConscript:
    compile ide devices
base/chunk_generator.hh:
    add another parameter to the chuck generator called complete() which
    returns the number of bytes transfered so far. Very useful for
    adding to a pointer.

mem/packet.hh:
    make senderstate void* per steve's request that we use every
    construct possible in C++
mem/physical.cc:
    have memory stamp the packet with the time.
mem/physical.hh:
    actually set the memory latency variable
python/m5/objects/Device.py:
    Add DmaDevice

316cdd0a19 dwarf debugging symbols make gdb much happier than stabs. Use them
and maximum debugging in for debug target.
No such thing as -O5 in GCC, so might as well just use -O3

609c4ecea6 Changed MIPS and Alpha to pass the syscall number to the syscall function
arch/alpha/isa/decoder.isa:
    Fixed up Alpha to pass the syscall number directly to the syscall function.
arch/mips/isa/decoder.isa:
    Fixed up MIPS to pass the syscall number directly to the syscall function.
arch/mips/isa/operands.isa:
    Added an R2 operand which is passed to the syscall function as the syscall number to use.

3d99b4a544 Fixes to SPARC syscall emulation mode.
arch/sparc/isa/base.isa:
    Added a set of abbreviations for the different condition tests.
arch/sparc/isa/decoder.isa:
    Fixes and additions to get syscall emulation closer to working.
arch/sparc/isa/formats/branch.isa:
    Fixed branches so that the immediate version actually uses the immediate value
arch/sparc/isa/formats/integerop.isa:
    Compute the condition codes -before- writing to the state of the machine.
arch/sparc/isa/formats/mem.isa:
    An attempt to fix up the output of the disassembly of loads and stores.
arch/sparc/isa/formats/trap.isa:
    Added code to disassemble a trap instruction. This probably needs to be fixed up so there are immediate and register versions.
arch/sparc/isa/operands.isa:
    Added an R1 operand, and fixed up the numbering
arch/sparc/isa_traits.hh:
    SyscallNumReg is no longer needed, the max number of sources and destinations are fixed up, and the syscall return uses xcc instead of icc.
arch/sparc/linux/process.cc:
arch/sparc/linux/process.hh:
    Added a getresuidFunc syscall implementation. This isn't actually used, but I thought it was and will leave it in.
arch/sparc/process.cc:
arch/sparc/process.hh:
    Fixed up how the initial stack frame is set up.
arch/sparc/regfile.hh:
    Changed the number of windows from 6 to 32 so we don't have to worry about spill and fill traps for now, and commented out the register file setting itself up.
cpu/cpu_exec_context.hh:
cpu/exec_context.hh:
