Abstract: PURPOSE:To prevent such a case where the same data are allocated double to a memory by storing the position data on an instruction containing the analysis omission data and carrying on an adverse upward processing after reading out the position data when the analysis omission data is detected at an adverse upward analysis. CONSTITUTION:An analyzing device 1 reads a source program out of an external storage 2 and assembles the source program via an assembler 3. An analysis preparation processing means 5 adds a row number to each instruction against the assembly program stored in an assembly list file 4. Based on this sorting of row numbers, various data files are produced. Then a structure analyzing means 11 performs the flow structure analysis processing in terms of a program file consisting of the machine words and the mnemonic codes stored in a storage part 6. At analysis processing the execution contents of each instruction are read with trace-back from a store instruction or a branch instruction. In this case, the position data containing the analysis omission data excluding a single branch instruction is stored. If the analysis omission data is detected at an adverse upward analysis, the position data is read out and the adverse upward processing is carried on.
