b7ebc2d97f Moved where some alpha specific source files were mentioned to be in the alpha specific Sconscript, and took advantage of the os specific directories for the process files.
arch/sparc/faults.cc:
    Remove fake fault, fix to have normal m5 line length limit, and change pointers to be const pointers so that the default faults aren't changed accidentally.
arch/sparc/faults.hh:
    Fix to have normal m5 line length limit, change pointers to const pointers.
arch/sparc/faults.hh:
    Added a typedef for the Addr type, and changed the formatting of the faults slightly.
arch/sparc/faults.hh:
    ur
    Using cleaned up fault class deiffinitions
arch/sparc/faults.hh:
    Added typedef for Addr
arch/sparc/faults.hh:
    Made Addr a global type
arch/sparc/faults.cc:
arch/sparc/faults.hh:
    Changed Fault * to Fault, which is a typedef to FaultBase *, which is the old Fault class renamed.
arch/sparc/faults.cc:
arch/sparc/faults.hh:
    Changed Fault to be a RefCountingPtr
arch/sparc/faults.cc:
arch/sparc/faults.hh:
    MachineCheckFaults and AlignmentFaults are now generated by the ISA, rather than being created directly.
arch/sparc/faults.cc:
arch/sparc/faults.hh:
    Put the Alpha faults into the AlphaISA namespace
arch/sparc/faults.cc:
arch/sparc/faults.hh:
    Moved the _stat for MachineCheckFault and AlignmentFault into the isa specific classes to prevent instantiation of the generic classes.
arch/sparc/faults.cc:
arch/sparc/faults.hh:
    Changed ev5_trap from a function of the execution context to a function of the fault. The actual function still resides in the execution context.
arch/sparc/faults.cc:
    AlphaFault is now an abstract class.
arch/sparc/faults.hh:
    AlphaFault is now an abstract class. Also, AlphaMachineCheckFault and AlphaAlignmentFault multiply inherit from both AlphaFault and from MachineCheckFault and AlignmentFault respectively. These classes get their name from the generic classes.
arch/sparc/faults.cc:
arch/sparc/faults.hh:
    moved ev5_trap fully into the fault class.
arch/sparc/faults.cc:
arch/sparc/faults.hh:
    Changed the name of the fault's invocation method from ev5_trap to invoke.
arch/sparc/faults.cc:
arch/sparc/faults.hh:
    Moved the fault invocation code into the fault class fully, and got rid of the need for isA.
arch/sparc/faults.cc:
arch/sparc/faults.hh:
    Got rid of the multiple inheritance in the Fault classes, and the base MachineCheck and Alignment faults.
arch/sparc/faults.cc:
    bk cp ../alpha/faults.cc faults.cc
arch/sparc/faults.hh:
    bk cp ../alpha/faults.hh faults.hh
SConscript:
    Moved the alpha specific source files into the alpha specific SConscript

arch/alpha/linux/process.cc:
arch/alpha/process.hh:

7c4c623302 Filled out the object file loader so it can load object files for several OSs and architectures.
SConscript:
    Added ./libelf as an include search directory. There might be a better spot for this than where I put it.
arch/SConscript:
    Combined the linux_process.h and tru64_process.h into process.h. This allows each ISA to support processes from arbitrary OSs.
arch/alpha/SConscript:
    Added process.cc as a source file. It provides an implementation of createProcess, which takes an object_file object and creates the appropriate process object, or dies.
base/loader/elf_object.cc:
    Actually extract the OS and architecture from the elf file, rather than always guessing Alpha and Linux.
base/loader/object_file.hh:
    Added constants for SPARC, MIPS, and Solaris, and changed the include for the Addr type.
sim/process.cc:
    Pushed creation of specific process objects into the ISA specific code.

99484cfae8 Create a Builder object for .isa files in arch/SConscript.
Start using SCons File objects to avoid fixed paths in
subordinate SConscripts.

SConscript:
    Push isa_parser stuff (including .isa scanner) down into
    arch/SConscript.
arch/SConscript:
    Create a Builder object for .isa files, including existing scanner.
    Return file objects generated by isa-specific SConscript
    back up to parent.
arch/alpha/SConscript:
arch/mips/SConscript:
arch/sparc/SConscript:
    Convert sources to scons File objects, so file names can be specified
    relative to the current directory.
    Invoke new builder for isa description, and get generated sources from
    there (instead of listing them explicitly).
arch/isa_parser.py:
    Get rid of third argument ("include_path").
    It was a pain to generate this from scons, and it turned out
    it's not needed anyway, since the only included file
    (decoder.hh) will be in the same directory as the sources.

19e5efed03 Pseudo instructions are now passed whatever instructions they need by the decoder, rather than extracting them explicitly. This lets most of the pseudo instruction code to be shared across architectures.
SConscript:
    Moved pseudo_inst.hh from targetarch to full system sources
arch/alpha/SConscript:
    Moved pseudo_inst.cc out of the alpha specific sources
arch/alpha/isa/decoder.isa:
    The decoder now pulls out the arguments for the pseudo instructions based on the alpha ABI
arch/alpha/isa/main.isa:
    Registers 16, 17 and 18 are used to get parameters for the pseudo instructions and can be referred to explicitly
sim/pseudo_inst.cc:
    Changed some include paths to reflect that pseudo_inst.hh is now outside of the alpha directory. Also, instead of extracting their parameters directly, they're passed in as regular function arguments.
sim/pseudo_inst.hh:
    Changed the function prototypes to include the functions parameters, now that they aren't extracted from the execution context.

89596f0cfa Some stuff aparently didn't get committed which was from before the new repository was created.
SConscript:
    There is a new SConscript in the arch/alpha directory which has the alpha specific files. To add files for an arch, a similar file should be created.
arch/isa_parser.py:
    The isa parser now supports include directives. These are done with ##include
build/SConstruct:
    The target directory is passed on so that the architecture specific SConscript can have it. Also, sparc was added as a valid architecture type.
arch/alpha/SConscript:
    This SConscript adds the alpha specific source
arch/sparc/isa_desc/operands.h:
    This sets up the operand types that the sparc isa uses
arch/sparc/isa_traits.cc:
    Implementation of sparc specific things, like a register file with windows
build/build_options/default/SPARC_SE:
    The default options for a sparc syscall emulation build.
