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. --HG-- extra : convert_revision : ea2dd81be1c2e66b3c684af319eb58f8a77fd49c
