Abstract

PURPOSE:To easily decide the consistency of translation information referred in respective compile units by using a linker having a means for inspecting and deciding translation history information. CONSTITUTION:The linker 20 inputs a compile unit 4 constituting a load module 6 and the other compile unit group 5. A translation history information deciding processing means 21 extracts the history information of translation information referred at the time of translation from the translation history information storing areas of respective inputted compile units, and if the same translation information appears in the extracted information, whether the information is the same translation information or not from the history information and outputs the decided result and respective inputted history information to a translation history information list 7. Consequently the consistency of the translation information can be easily decided.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for checking a compilation unit of a source program written in a high-level language, and particularly relates to a method for checking a compilation unit that allows easy determination of the identity of information at the time of translation. It is something.

(Prior art) Conventionally, the compilation unit generated by translating a source program only stores history information such as the number of revisions and the revision start of the translated source program, and it can be referenced from the source program. The translation information name and history information of the translation information (reports +? referenced in FORTRAN (17) INCLUDE statement, C0BOL C0PY instruction, Ada U38 clause, etc.) necessary for the translation of the source program are stored. It wasn't.

(Problem to be Solved by the Invention) In such a conventional method, since there is no history information of the translation time information referred to during translation in the compilation unit, it is difficult to know which translation time information the compilation unit was generated with reference to. The determination was made by referring to the list used when specifying translation and the list of translated results.

Therefore, when combining multiple compilation units that refer to the same translation time information, the sameness of the translation time information is determined by comparing and referring to the list used when specifying translation and the list of translated results. It was done in a way. This method has the disadvantage that it takes time to make the determination and requires the entire list.

(Means for Solving the Problems) The compile unit inspection method according to the present invention inputs a source program and its history information, stores the history information in a history information storage area, and furthermore, the source program is referenced from within the source program. history information storage means for inputting translation time information necessary for program translation, and storing the translation time information name and translation time history information in a history information storage area; a compiler including translation history information setting means for storing history information in a translation history information storage area secured in a compilation unit; and each translation information name referenced during translation from the translation history information storage area in the compilation unit; and its history information and outputs it to the translation history list.If there is a compilation unit that references the same translation time information name in the load module, check whether the same translation time information is referenced or not. and a linker including a translation history information inspection processing means for outputting the results of the determination to the translation history list.

(Example) Next, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a processing configuration diagram showing an embodiment of a compile unit checking method according to the present invention.

A compiler 10 inputs a source program 1a of a source program file 1 written in a high-level programming language and source program history information 1b. Next, the compiler 10 selects a reference translation information file group 3 that stores translation information to be referenced in the source program 1a from among the translation information file group 2 specified at the time of translation.
Select the translation information 3a of each translation information file.
and input the history information 3b of the information at the time of translation. The history information storage means 11 converts the input source program history information 1b and the history information 3b of each translation information into the format of the history information storage area 10a and stores them.

The translation history information setting means 12 includes the compile unit 4
A translation history information storage area 4a is secured in the translation history information storage area 4a, and the information of the history information storage area 10a is stored therein.

The compiler 10 outputs a compile unit 4 including a translation history information storage area 4a.

The linker 20 inputs the compile unit 4 and other compile unit groups 5 that constitute the load module 6. The translation history information determination processing means 21 extracts the history information of the translation time information referred to during translation from the translation history information storage area of each input compile unit, and if the same translation time information name appears therein, It is determined from the history information whether or not they are the same information at the time of translation, and the determination result and each input B original information are output to the translation history information restore.

Figure 2 shows the FORTRA input to the compiler in Figure 1.
FIG. 2 is an explanatory diagram showing an example of a source program file 1 written in the N language and a group of translation information files 3 referenced in the translation thereof.

The compiler 10 inputs the source program 1a of the source program file 1 and the source program history information 1b. The compiler 10 extracts the translation information name 201 from the translation information reference sentence 200 of the input source program 1a, and extracts the translation information file group 2 specified at the time of translation.
The translation time information 30 in which the translation time information is stored is selected from . Then, from the selected translation information file 30, translation information 30a and translation information history information 30
Enter b.

Subsequently, the history information storage means 11 stores the history information 30b of the translation information in the history information storage area 10a. The compiler 10 inputs the translation time information 32a referred to in the translation time information reference sentence 210 in the input translation time information 30a and the translation time information history information 32b. The history information 32'b at the time of translation is stored in the history information storage area 10a by the history information storage means 11.

The compiler 10 repeats this process for the input translation information until there is no more translation information referenced therein, and when the processing for the translation information in the input translation information is completed, the compiler 10 converts the source program This process is delayed until there are no more reference sentences in the translation information of 1a.

FIG. 3 shows an example of storage in the footwear 2 information storage area 10a of FIG. 1. That is, the source program name or the translation information name, the number of revisions, the number of lines, the date of creation, the last revision, the history information of the translation information, and the history information of the source program are stored.

(Effects of the Invention) As explained above, the present invention provides a means for adding history information of translation information referred to during translation into a compilation unit of a source program written in a high-level language, and for inspecting and determining the translation history information. By using a linker with this function, it becomes possible to easily determine the identity of the translation information referenced in each compilation unit.
