Abstract

PURPOSE:To eliminate difficulty and misreading by the visual inspection of a compiler output list and to reduce man-hours by providing a code part comparing means which compares the code part of an object program with a source program, statement by statement. CONSTITUTION:An object program storage library input part 42 reads the code part of an object program before modification out of a before-modification program storage library 16 and the code part of an object program after modification out of an after-modification program storage library 18 from their head lines,statement by statement. An object program comparing part 43 compares the read object program before modification with the object program after modification and output source statements and pieces of code information of both programs to a printing means when the contents are not coincident with each other.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an automatic inspection method for a target program of a compiler in compiler development technology, and in particular, a method for comparing target programs compiled by a compiler before modification and a compiler after modification. Concerning an automatic inspection method for a compiler's target program.

[Conventional technology]

Conventionally, in the development of compilers such as COBOL and HPL, the compiler inspection method after development and modification has been to compile a large number of inspection programs and perform visual inspection on the output list, or to create an inspection program with a sufficiently high coverage rate. Methods such as compiling and checking the operation of the target program were used.

[Problem that the invention seeks to solve]

In the conventional compiler inspection method described above, it takes time to visually inspect the compilation results of the inspection program, and inspection omissions such as oversights easily occur.In addition, the compiler output part that is not output on the list, that is, the target program The disadvantage is that it is not possible to inspect parts such as connection information, and one has to rely on execution tests using an inspection program. That is, in an execution test of an inspection program, the running coverage rate of the program is a problem, and the running test requires a lot of man-hours.

An object of the present invention is to provide an automatic inspection method for a target program of a compiler that automatically compares information regarding a compiler before modification and a compiler after modification and prints out the differences between the two.

[Means for solving problems]

The automatic inspection method for the object program of a compiler according to the present invention includes a compiler control means for controlling the execution of a compiler before modification and a compiler after modification, and a combination information for comparing the combination information part of the object program output by each of the compilers. a data definition section comparison section that compares data definition sections of the target program; a code section comparison section that compares code sections of the target program source statement by source statement; and a data definition section comparison section that compares the output list image of the target program. performance comparison means for comparing performance such as elapsed time, CPU usage time, execution memory size, etc. of each of the compilers; and printing means for printing out the results of comparison by each of the comparison means.

〔Example〕

Next, the present invention will be explained in detail with reference to the drawings.

Referring to FIG. 1, one embodiment of the present invention includes a compiler control means 1, a combination information part comparison means 2, a data definition part comparison means 3, a code part comparison means 4, an output list comparison means 5,
It is composed of a performance comparison means 6 and a printing means 7.

Referring to FIG. 2, the compiler control means 1 includes a pre-modification compiler execution environment setting unit 11, a pre-modification compiler execution control unit 12, a post-modification compiler execution environment setting unit 13, and a post-modification compiler execution control unit 14. There is.

Referring to FIG. 3, the code section comparing means 4 is comprised of a list image storage library input section 41, a target program library input section 42, and a target program comparison section 43.

Next, the operation of the present invention will be explained with reference to the drawings.

First, the compiler control means 1 will be explained.

The pre-modification compiler execution environment setting unit 11 sets a source program storage library 15, a pre-modification target program storage library 16, and a pre-modification list image storage library 17, respectively.

The pre-modification compiler execution control unit 12 causes the pre-modification compiler 8 to compile the source program in the set source program storage library 15, pre-modification target program storage library 16, and pre-modification list image storage library 17, and as a result, the pre-modification compiler 8 compiles the source program. The pre-modification target program is stored in the pre-modification target program storage library 16, and the output result list is stored in the pre-modification list image storage library 17.

The modified compiler execution environment setting unit 13 sets a source program storage library 15, a modified target program storage library 18, and a modified list image storage library 19, respectively.

The post-modification compiler execution control unit 14 compiles the same source program that was compiled by the pre-modification compiler 8 in the set source program storage library 15, post-modification target program storage library 18, and post-modification list image storage library 19. The modified compiler 9 is executed, the resulting modified target program is stored in the modified target program storage library 18, and the output result list is created as a modified list image.
The data is stored in the file storage library 19.

The combination information section comparison means 2 reads the pre-modification target program from the pre-modification target program storage library 16 and the post-modification target program from the post-modification target program storage library 18, and combines the pre-modification target program and the post-modification target program. When the information parts are compared and the contents do not match, the information is printed by the printing means 7.

The data definition section comparison means 3 reads the pre-modification objective program from the pre-modification objective program storage library 16 and the post-modification objective program from the post-modification objective program storage library IB, and reads the data of the pre-modification objective program and the post-modification objective program. When the definition parts are compared and the contents do not match, the information is printed by the printing means 7.

The code part comparing means 4 inputs the code part of the list image stored in the list image storage library 17 before modification and the list image storage library 19 after modification by the list image storage library input part 41 starting from the first line in units of source statements. Then, the target program storage library input unit 42 reads the code portions of the pre-modification target program from the pre-modification target program storage library 16 and the modified target program from the post-modification target program storage library 18 from the first line in source statement units, and The contents of the pre-modification target program and the post-modification target program read by the program comparison unit 43 are compared, and if the contents do not match, the corresponding source statements of the pre-modification target program and the post-modification target program and the pre-modification target program are compared. The code information of the target program and the code information of the modified target program are printed by the printing means 7.

The output list comparison means 5 compares the formats on the output list, and compares the formats on the output list read from the pre-modification list image storage library 17 and the post-modification list image storage library 19, and determines whether the results are inconsistent. In this case, the information is printed by the printing means 7.

The performance comparison means 6 reads the compile execution report from the pre-modification list image storage library 17 and the post-modification list image storage library 19, compares the execution status of the compiler (execution memory size, elapsed time, etc.), and compares the compiler execution status (execution memory size, elapsed time, etc.), and compares the compiler execution status (execution memory size, elapsed time, etc.), and compares the compiler execution status (execution memory size, elapsed time, etc.), and compares the compiler execution status (execution memory size, elapsed time, etc.). is printed by the printing means 7.

〔Effect of the invention〕

The present invention makes it easy to understand the differences by logically comparing all the information output by the compiler before and after the modification according to each information part when a compiler is developed and modified. Editing and printing out on the list has the following effects.

■ Eliminates the difficulty and oversight caused by visual inspection of the compiler output list, significantly reducing man-hours.

■ Differences such as malfunctions and improvements of the compiler due to modifications can be accurately confirmed for all data parts, link information parts, code parts, and output lists of the target program generated by the compiler.
