a8fbc4ec76 Got hello world to work!
arch/sparc/isa/decoder.isa:
    Made sure if a register was assigned to along some control path, then all paths on which no exception would block commit set a value as well. Also, Rs1 is treated as signed for bpr instructions.
arch/sparc/isa/formats/integerop.isa:
    Added an IntOpImm11 class which sign extends the SIMM11 immediate field.
arch/sparc/isa/formats/mem.isa:
    Fixed how offsets are used, and how disassembly is generated.
arch/sparc/linux/process.cc:
    Added fstat and exit_group syscalls.

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:
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.

arch/sparc/isa/includes.isa:
arch/sparc/isa/operands.isa:
    Fixes towards running in syscall emulation mode.
arch/sparc/linux/process.cc:
    Fixed the assert and comment to check that the Num_Syscall_Descs is less than or equal to 284. Why does this assert need to exist anyway?
base/loader/elf_object.cc:
    Cleared out comments about resolved issues.
cpu/simple/cpu.cc:
    Use NNPC for both SPARC and MIPS, instead of just MIPS
configs/test/hello_sparc:
    A test program for SPARC which prints "Hello World!"

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.
