Gabe Black 6d8d6d15cd Fixed up the isa description. Also added some capability to the isa_parser in the InstObjParams constructor.
arch/isa_parser.py:
    Expanded the capability of the InstObjParams constructor to allow adding in extra keys for use in templates. These are added as key, value tuples as optional arguements.
arch/sparc/isa/base.isa:
arch/sparc/isa/formats/mem.isa:
arch/sparc/isa/formats/priv.isa:
    The genCompositeIop function is no longer needed, as this functionality is now in the InstObjParams constructor.
arch/sparc/isa/decoder.isa:
    Fixed up alot of instructions, and fixed indentation.
arch/sparc/isa/formats/integerop.isa:
    The genCompositeIop function is no longer needed, as this functionality is now in the InstObjParams constructor. Also changed the immediate values to be signed.
base/traceflags.py:
    Added SPARC traceflag
configs/test/hello_sparc:
    Recompiled without -mflat
cpu/cpu_exec_context.cc:
    Used the regfile clear function rather than memsetting to 0.

Kevin Lim 0b2deb2a88 Fixes for full system compiling.
arch/alpha/arguments.cc:
    There will not be a phys mem ptr in the XC in the newmem.  This read will have to go through something else.
arch/alpha/ev5.cc:
    Remove instantiations of these functions for the FastCPU, as the FastCPU is not really used.  Also this messed up the ability to specify which CPU models are being built.
cpu/exec_context.hh:
    Remove getPhysMemPtr() function.
cpu/exetrace.cc:
    Include sim/system.hh, and sort the includes.
cpu/simple/cpu.cc:

Kevin Lim f15e492375 Steps towards setting up the infrastructure to allow the new CPU model to work in full system mode.
The major change is renaming the old ExecContext to CPUExecContext, and creating two new classes, ExecContext (an abstract class), and ProxyExecContext (a templated class that derives from ExecContext).

Code outside of the CPU continues to use ExecContext as normal (other than not being able to access variables within the XC).  The CPU uses the CPUExecContext, or however else it stores its own state.  It then creates a ProxyExecContext, templated on the class used to hold its state.  This proxy is passed to any code outside of the CPU that needs to access the XC.  This allows code outside of the CPU to use the ExecContext interface to access any state needed, without knowledge of how that state is laid out.

Note that these changes will not compile without the accompanying revision to automatically rename the shadow registers.

SConscript:
    Include new file, cpu_exec_context.cc.
