COMPUTER FOR CALCULATING NUMBER OF PIECES OF TRACE INFORMATION, METHOD OF CALCULATING NUMBER OF PIECES OF TRACE INFORMATION AND PROGRAM FOR CALCULATING NUMBER OF PIECES OF TRACE INFORMATION

摘要

PROBLEM TO BE SOLVED: To obtain the number of pieces of trace information acquired by trace before executing a program to determine a size of a buffer for storing the trace information.SOLUTION: Program components for controlling flow of a program to be executed are extracted from a source code or binary, and a program component tree in which they are determined as nodes is generated on the basis of a control flow (S203). Then, from the number of nodes configuring the generated program component tree, the number of program components to be executed in the execution of one time of a program is specified, and the number of pieces of the trace information of the program to be executed is calculated on the basis of the specified number of the program components. Also, from the calculated number of pieces of trace information, the size of a buffer which is a memory area for storing the trace information is determined (S205).
