gem5/arch/alpha/isa_traits.hh
Korey Sewell 4d19bbeeeb MIPS is back to compiling and building now!
arch/alpha/isa_traits.hh:
    used for SimpleCPU instead of explicitly calling the namespace we declare in isa_traits.hhs
    so other archs. can use SimpleCPU
arch/mips/SConscript:
    dont include common_syscall or tru64
arch/mips/faults.cc:
arch/mips/faults.hh:
arch/mips/isa/formats/unimp.isa:
arch/mips/isa/formats/unknown.isa:
    Change Faults to new format
arch/mips/isa/decoder.isa:
    Fix readMiscReg access
    Made change so that you cant explicitly tell if a instruction nop,ehb,or ssnop... These are all variants
    of the sll instruction so I may need to make a separte class of instructions to handle thse better
arch/mips/isa/includes.isa:
    add isa_traits.hh and MipsISA included into every auto-gen file
arch/mips/isa_traits.cc:
    create copyMiscRegs function...
    delete useless code
arch/mips/isa_traits.hh:
    clean up for build
arch/mips/linux_process.cc:
    mem is now getMemPort(), linux process objects now take in a system argument
arch/mips/linux_process.hh:
    new argument for linux process
arch/mips/process.cc:
    add system
arch/mips/process.hh:
    add system variable
cpu/cpu_exec_context.cc:
    Change AlphaISA to TheISA
cpu/exec_context.hh:
    add readNextNPC and setNextNPC functions
cpu/simple/cpu.cc:
    include isa_traits for namespace declariation
cpu/simple/cpu.hh:
    PC & NPC access/modify functions
arch/mips/utility.hh:
    file needed for compile
