arch/sparc/faults.cc:
arch/sparc/faults.hh:
Implemented the SPARC fault classes. The invoke method still needs to be written, but this depends on the misc regfile.

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.

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:

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.

Formatting & doxygen.
arch/sparc/linux_process.cc:
Added some more ioctl commands to ignore.
Set unlink and rename to the new functions.
Ignore setrlimit, times and rt_sigaction.

arch/sparc/linux_process.cc:

arch/sparc/linux_process.cc:
fixup for bsd hosts. Some headers are included by default which means that
more variables need TGT_ prefixes and there isn't a stat call (everything
is a stat64 call) so we have to work around that a bit

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.

the isa_desc files, movement of byte_swap.hh into sim, and the creation of arch/isa_traits.hh

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.
