ABSTRACT:
A compiler apparatus that improves the performance of loop processing. The compiler apparatus translates a C program that includes a loop into a machine language program, and includes: a movement judgment unit that judges whether or not an instruction which is positioned outside of the loop of the C program can be moved into the loop, based on a state of live ranges of variables used in the instruction; a movement execution unit that moves the instruction into the loop in the case where the movement judgment unit judges that the instruction can be moved into the loop, thereby generating an intermediate program; and a translation unit that translates the intermediate program into the machine language program.
