A compiling device according to an example of the invention comprises a unit which allocates a code to a pseudo register having an infinite storage area, a unit which judges whether or not a register live range for the pseudo register is of a scalar used type or an SIMD used type, a unit which secures an SIMD physical register for spilling, in a case where it is judged that the register live range can not be allocated to the physical register and that the register live range is of the scalar used type, and a unit which allocates a part or all of the code of the register live range to the SIMD physical register for spilling, allocates a remaining code of the register live range to the physical register, and allocates, to the physical register, a register spilling code instead of a part or all of the code of the register live range, in a case where the SIMD physical register for spilling is secured.
