PROBLEM TO BE SOLVED: To provide a compiling method, a program and an information processing apparatus that are capable of lowering a CPU load and decreasing memory consumption by reducing guard codes which need to be embedded in a compiled code, when an indirect branch instruction is included in a machine language code to be compiled.SOLUTION: The compiling method implemented by an information processing apparatus includes the steps of: generating intermediate code from a trace, which is an instruction sequence described in a machine language; computing an offset between an address value, which is a base point of an indirect branch instruction, and a start address of a memory page, which includes a virtual address referred to by the information processing apparatus immediately after processing a first instruction; determining whether processing jumps to another memory page, using as an offset a value obtained by adding a displacement made by an indirect branch instruction, which is a second instruction subsequent to the first instruction; and optimizing the intermediate code by using the result of the determining step. |
