* sim-main.h (Nan, Infinity, Less, Equal, AbsoluteValue, Negate) (Add, Sub, Multiply, Divide, Recip, SquareRoot): Move lower in file, remove PARAMS from prototypes. (value_fpr, store_fpr, convert): Likewise. Use SIM_STATE to provide simulator state arguments. (ValueFPR, StoreFPR, Convert): Move lower in file. Use SIM_ARGS to pass simulator state arguments. * cp1.c (SD): Redefine as CPU_STATE(cpu). (store_fpr, convert): Remove 'sd' argument. (value_fpr): Likewise. Convert to use 'SD' instead.
