IPC: G06F11/28
Filed: 1991-03-08
Abstract: PURPOSE:To facilitate the tracing of a program by securing a storage area based on the identifier of the execution program, changing the flow of the program and storing an execution address before alteration in the storage area based on the identifier. CONSTITUTION:In a storage judgement processing process 1, the identifier of the execution program is judged. When the identifier is logic '1', for example, the storage area (not illustrated) is secured. Then, flow alteration processing processes 2a-2d change the flow of the execution program and stores the execution address before alteration in the storage area based on the identifier of the execution program. Parts 3a-3i connecting the flow alteration processing processes 2a-2d show the processing part of the real function of the program. Thus, the execution address immediately before the flow of the processing changes can be stored and the processing of the program can easily be traced. Thus, the efficiency of fault analysis can be improved.
