Document Type and Number:
Japanese Patent JP5840014
Kind Code:
B2
Abstract:
A method, program, and apparatus for optimizing compiled code using a dynamic compiler. The method includes the steps of: generating intermediate code from a trace, which is an instruction sequence described in 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 an indirect branch instruction that is subsequent to the first instruction causes processing to jump to another memory page, by using a value obtained from adding the offset to a displacement made by the indirect branch instruction; and optimizing the intermediate code by using the result of the determining step.
