Abstract

PURPOSE:To shorten a translating time and to decrease storing resource to be used by judging whether the intermediate text of a source program, which is translation- processed in the past, can be re-utilized for this time of a translation processing, correcting the intermediate text based on correcting information when the intermediate text can be re-utilized and executing the translation processing. CONSTITUTION:A re-utilization possibility judging means 11 judges whether an intermediate text 4b, which is generated when a source program 2a is translated in the past, is stored in an intermediate text storing means 4 or not and when it is judged that the intermediate text is stored, whether the intermediate text is in a using condition or not is judged based on correcting information 3a. When it is judged that the intermediate text can be re-utilized by the re-utilization possibility judging means 11, an intermediate text re-utilization means 12 corrects the intermediate text 4b on the basis of the correcting information 3a. When it is judged by the re-utilization possibility judging means 11 that the intermediate text 4b can be re-utilized, a translating means 13 re-utilizes the intermediate text, which is corrected by the intermediate text re-utilizing means 12, and executes the translation processing. Thus, the translating time is shortened and the storing resource to be used can be decreased.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a translation processing method in a language processing system that generates a target program from a source program, and particularly relates to a translation processing method for retranslating a source program that has been translated in the past. The present invention relates to a retranslation processing method that can speed up translation processing.

[Conventional technology]

Conventionally, when translating a source program to generate a target program, the source program to be translated is the same as a source program that has been translated once in the past, or only a part of it has been changed; Even if the intermediate text generated in the translation process is still available for reference in the current translation process, there may be differences between the source program being translated this time and source programs translated in the past. Since there was no way to obtain points, the intermediate text created in the past translation process was not reused, but the translation process was restarted from the beginning.

That is, conventionally, as shown in FIG. 4, when a source program 31a that has been translated once in the past and is stored in the source program storage means 31 is to be translated again, the process is started from the start of translation in step S34. , step 3
In the intermediate processing of step S35, an intermediate text 32a is generated and stored in the intermediate text storage means 32, and in the translation end processing of step S36, a target program 33a is generated and stored in the target program storage means 33.

[Problem that the invention seeks to solve]

As mentioned above, conventionally, even when translating a source program that is the same as, or only partially different from, a source program that has been translated once in the past, the translation process is restarted from the beginning. The same time resources as during the previous translation process.

There was a problem that storage resources were required.

The present invention solves these problems, and its purpose is to shorten the processing time when retranslating a source program that is the same as or only partially different from a previously translated source program. The purpose is to reduce the amount of storage space used.

[Means for solving problems]

In order to solve these problems, the present invention uses a translation processing method in a language processing system that generates a target program from a source program, in which intermediate text created in past translation processing is stored. The intermediate text storage means in which the source program is being translated and the source program that is the target of translation processing have been translated in the past, and it is determined whether or not the intermediate text generated at that time exists in the intermediate text storage means. Correction information indicating how the description of the source program that is the target of the translation process has been modified from the description that was the target of the translation process in the past. reusability determining means for determining whether or not it is possible to translate the source program that is the target of the translation processing using the intermediate text stored in the intermediate text storage means based on and the reusability determining means determines that it is possible to translate the source program to be translated using the intermediate text stored in the intermediate text storage means, thereby updating the modification information. intermediate text reuse means for modifying the intermediate text in the intermediate text storage means based on the intermediate text storage means; and translation means for performing translation processing; When it is determined that the intermediate text exists, translation processing is performed using the intermediate text modified by the intermediate text reusing means.

[For production]

The reusability determining means determines whether the source program targeted for translation processing this time has been translated in the past and the intermediate text generated at that time is stored in the intermediate text storage means. By determining that the intermediate text is usable, it is determined whether the intermediate text generated in the previous translation process can be used based on the modification information. When the intermediate text reuse means is determined to be reusable by the reusability determination means,
Modify intermediate text based on modification information. When the reusability determination means determines that the intermediate text can be reused, the translation means reuses the modified intermediate text by the intermediate text reuse means to perform translation processing.

〔Example〕

Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, which includes a translation processing section 1, a source program storage means 2 in which a source program 2a is stored, a modification information storage means 3 in which modification information 3a is stored, Table of contents information 4a and intermediate text) 4
The intermediate text storage means 4 has an intermediate text storage means 4 in which the object program 5a is stored, and an object program storage means 5 in which the object program 5a is stored. Translation processing unit 1 is reusability determination means 1
1, intermediate text reuse means 12, and translation means 13. The table of contents information 4a stored in the intermediate text storage means 4 is information (eg, source program name) that uniquely indicates the source program corresponding to the intermediate text stored in the intermediate text storage means 4.

FIG. 2 is a flowchart showing a processing example of the reusability determining means 11, and FIG. 3 is a flowchart showing a processing example of the intermediate text reuse means 12. The operation of this embodiment will be explained below with reference to each figure. explain.

When the source program 2a stored in the source program storage means 2 is input, the reusability determination means 11 in the translation processing unit 1 stores it in the intermediate text storage means 4 as shown in the flowchart of FIG. Referring to the table of contents information 4a, it is determined whether the input source program 2a has been translated in the past and the intermediate text generated at that time exists in the intermediate text storage means 4 (step 5ll). ), in step 311,
If it is determined that it exists, the modification information 3a stored in the modification information storage means 3 (if the source program 2a to be processed this time is exactly the same as the previous translation processing, information indicating that but if they are different, information indicating the correction position and correction content is stored).
It is determined whether the description of the source program 2a that is currently being translated satisfies any of the following conditions (step 312).

■It has not been modified at all.

■Only the constant values have been modified. Here, the constant is
For example, it refers to 1 in X-Y+1.

■The content of the source program is the same, but the line and column (indicating the number of characters in the line) have been modified.

An example of a line being modified when source programs have the same content is, for example, insertion of a comment line, and an example of a source program having the same content and a digit modified is, for example, when a line is modified using a Do statement. In order to make the loop easier to distinguish from other parts, there are modifications such as shifting the position of the first character in each line that makes up the loop.

In step S12, if it is determined that any of the conditions (■ to ■) above are satisfied, the reusability determination means 11 supports the source program 2a stored in the intermediate text storage means 4. It is determined that it is possible to reuse the intermediate text (in this embodiment, it is referred to as intermediate text 4b), and the condition information indicating which of the conditions ■ to ■ above is satisfied is reused as the intermediate text. It is sent to the means 12 (step 513). In addition, if it is determined in step 312 that all of the above conditions (■ to ■) are not satisfied, and if it is determined in step Sll that there is no intermediate text corresponding to the source program 2a, the intermediate text storage means It is determined that the intermediate text stored in 4 cannot be reused, and the translation means 1
3 (step 514).

Intermediate text reuse means 12 is reusability determination means 1
When the condition information is sent from the source program 2a, the process shown in the flowchart of FIG. 3 is performed according to the condition information. If it is determined that the modification has not been made (if the determination result in step S21 is YES), the translation means 13 is instructed to perform translation processing using the intermediate text) 4b (step 326), and only the value of the constant is If it is determined that the correction has been made (if the judgment result in step 322 is YES), the part that expresses the value of the constant in the intermediate text 4b corresponding to the source girogram 2a that is currently being translated is changed into correction information 3a. After making corrections according to the following (step 324), perform the process of step 326, and if it is determined that only one digit of the line has been corrected (if the judgment result of step 323 is Y[!S), the translation process will be performed this time. After modifying the portion corresponding to the one-digit line number in the intermediate text l-4b corresponding to the source program 2a in accordance with the modification information 3a (step 325), the process of step S26 is performed.

When the translation means 13 receives an instruction from the intermediate text reusing means 12 to perform translation processing using intermediate text, it selects one of the intermediate texts stored in the intermediate text storage means 4 as the target for translation processing this time. Translation processing is performed using the intermediate text 4b corresponding to the source program 2a, and the generated target program 5a is stored in the target program storage means 5. Further, when the translation means 13 receives a notification from the reusability determination means 11 that the intermediate text cannot be reused, the translation means 13 uses the source program 2a
Start the translation process from the beginning.

〔Effect of the invention〕

As explained above, the present invention is capable of reusing intermediate text in the intermediate text storage means in which intermediate text of a source program that has been translated in the past is stored in the current translation process. If it is determined that it can be reused, the intermediate text reuse means modifies the intermediate text based on the modification information, and the modified intermediate text is used to translate the text. Translation processing is performed by means of translation processing, and as part of the retranslation processing, the processing up to the generation of intermediate text can be omitted, so it has the effect of shortening translation time and is also used in translation processing. It also has the effect of reducing the amount of memory resources required.
