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:
cpu/simple/cpu.hh:
sim/process.cc:
sim/process.hh:
    Changed the syscall mechanism to pass down the syscall number directly.

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:

    The genCompositeIop function is no longer needed, as this functionality is now in the InstObjParams constructor.

    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.

a4b31e8f6b Enable register windows.
arch/alpha/isa_traits.hh:
arch/mips/isa_traits.cc:
    Turned the integer register file into a class instead of a typedef to an array.
arch/alpha/regfile.hh:
    Changed the integer register file into a class instead of a typedef to an array. Also put the parts of the register file, ie the int, float, and misc register files, pc, npc, and nnpc, behind accessor functions. Added a changeContext function, and ContextParam and ContextVal types, so that things like the register window can be changed through call backs.
arch/mips/isa_traits.hh:
    Turned the integer register file into a class instead of a typedef to an array. Also moved a "using namespace" into the namespace definition.
arch/sparc/isa_traits.hh:
    Turned the integer register file into a class instead of a typedef to an array. Also "fixed" the max number of src and dest regs. They may need to be even larger.
arch/sparc/regfile.hh:
    Changed the integer register file into a class instead of a typedef to an array. Also put the parts of the register file, ie the int, float, and misc register files, pc, npc, and nnpc, behind accessor functions. Added a changeContext function, and ContextParam and ContextVal types, so that things like the register window can be changed through call backs. Created setCWP and setAltGlobals functions for the IntRegFile.
cpu/cpu_exec_context.hh:
    Used the accessor functions for the register file, and added a changeRegFileContext function to call back into the RegFile. Used the RegFile clear function rather than memsetting it to 0.
cpu/exec_context.hh:
    Added the changeRegFileContext function.
cpu/exetrace.cc:
    Use the TheISA::NumIntRegs constant, and use readReg now that the integer register file is a class instead of an array.
cpu/exetrace.hh:
    Get the address of the regs object, now that it isn't an array.

base/loader/elf_object.cc:
    Cleared out comments about resolved issues.

efc41fe82d Make .isa-file ##include file paths relative to including file.
Makes .isa files cleaner and simplifies scanner too.
Simplified scanner to work under both old and new versions of scons.

arch/SConscript:
    Simplify .isa scanner... seems to work with both scons 0.96.1 and 0.96.91 now.
    Assumes .isa ##include paths are relative to including file.

arch/mips/isa/main.isa:
arch/sparc/isa/formats.isa:
arch/sparc/isa/main.isa:
    Make ##include paths relative to including file.
arch/isa_parser.py:
    Make ##include file paths relative to including file.
    Makes .isa files cleaner and simplifies scanner too.
    Partial rewrite of include-handling code to use cool re.sub() feature
    where you can specify a function to provide the replacement string.
    Minor cleanup of error-handling code.
    Also got rid of '#!' at top to make caller choose which python interpreter
    is used (since SPARC now requires 2.4 to build, we may need to do that via
    scons in the future).

818f3ae22f SPARC compiles for SE!
arch/sparc/isa/decoder.isa:
    Replaced register number munging with RdLow and RdHigh operands.
arch/sparc/isa/formats/mem.isa:
    Fixed how the address calculation code is dealt with.
arch/sparc/isa/operands.isa:
    Changed the tabbing so that the whole oeprands block was consistent, and added RdLow and RdHigh operands. These registers are used when Rd is meant to refer to a pair of registers, rather than just one.
arch/sparc/isa_traits.hh:
    Moved some functions to the new (to SPARC) utility.hh file. Also, dummy Fpcr_DepTag and Uniq_DepTag DepTags were added to pacify Tru64. These need to be removed, and Tru64 needs to not be compiled in if it isn't appropriate.
arch/sparc/regfile.hh:
    Changed regSpace to have the correct size.
arch/sparc/utility.hh:
    A new file for sparc to match the one for alpha.

    instead of magic numbers

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.

    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.

    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.

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.
