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 --HG-- extra : convert_revision : 29a327e79c51c6174a6e526aa68c7aab7e7eb535
