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.

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.

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.

82f2ae56ed Alot of changes to push towards ISA independence. Highlights are renaming of the isa_desc files, movement of byte_swap.hh into sim, and the creation of arch/isa_traits.hh
SConscript:
    Moved some files out of targetarch. The either no longer need to be there, never needed to be there, or should be referred to directly in arch/alpha due to there strictly alpha content.
arch/alpha/isa_traits.hh:
    Added alpha's endianness to it's isa_traits.hh
arch/mips/isa_traits.hh:
    Added MIPS endianness to it's isa_traits.hh
arch/sparc/isa_traits.hh:
    Added SPARCs endianess to it's isa_traits.hh
build/SConstruct:
    Added MIPS as a valid architecture
cpu/exec_context.hh:
    Included arch/isa_traits.hh to bring in the endianness of the system.
cpu/o3/alpha_cpu.hh:
    Included arch/isa_traits.hh to bring in the systems endianness, and removed the hardcoding of little endianness
cpu/o3/fetch_impl.hh:
kern/freebsd/freebsd_system.cc:
    Included arch/isa_traits.hh to bring in the systems endianness, and removed the hardcoding to little endianness.
sim/system.cc:

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.
