摘要

PPROBLEM TO BE SOLVED: To facilitate the debugging of a dynamic compiler by reproducing the same execution instruction sequence as an execution instruction sequence generated by the dynamic compiler. PSOLUTION: A compiler program allows a computer to function in the following ways: an execution state acquisition section acquires the execution state of a program; a dynamic compiling section generates a different execution sequence in accordance with the execution state by compiling part of a program to be executed based on the execution state in the course of executing the program; an execution state recording section records the execution state on a storage region allocated to the memory of the computer; a file reading section reads a file including the contents of the storage region allocated to the memory saved on a storage device by the computer from the storage device; and a reproducible compiling section generates the same execution instruction sequence as the execution instruction sequence generated by the dynamic compiling section in the course of executing the program by compiling part of the program based on the execution state acquired from the file.
