arch/alpha/arguments.cc:
Renamed readFloatRegInt to readFloatRegBits
arch/alpha/ev5.cc:
Removed the Double from setFloatRegDouble
arch/alpha/registerfile.hh:
Changed the floating point register file from a union of arrays to a class with appropriate accessor functions. The interface is necessary for SPARC.
arch/alpha/types.hh:
Changed the FloatReg type from a union of uint64_t and double to a double, and defined a new type FloatRegBits which is a uint64_t and is used to return the bits which compose a floating point register rather than the value of the register.
arch/isa_parser.py:
Adjusted the makeRead and makeWrite functions to generate the new versions of readFloatReg and setFloatReg.
base/remote_gdb.cc:
kern/tru64/tru64.hh:
Replaced setFloatRegInt with setFloatRegBits
cpu/cpu_exec_context.cc:
Removed the duplicated code for setting the floating point registers, and renamed the function to setFloatRegBits and readFloatRegBits.
cpu/cpu_exec_context.hh:
cpu/exec_context.hh:
cpu/o3/alpha_cpu_impl.hh:
cpu/o3/alpha_dyn_inst.hh:
cpu/o3/cpu.cc:
cpu/o3/cpu.hh:
cpu/o3/regfile.hh:
cpu/ozone/cpu.hh:
cpu/simple/cpu.hh:
Implemented the new versions of the floating point read and set functions.
cpu/simple/cpu.cc:
Replaced setFloatRegDouble with setFloatReg
