JPH0728629A - Source program tuning system using general purpose editor - Google Patents

Abstract

PURPOSE:To provide a tuning assistance system which enables tuning operation on a window system, which can not display plural windows at the same time, without using any special editor. CONSTITUTION:The source program of an original source program is outputted to source program parts 51, 53, and 55 and comments of tuning information which is automatically inserted into tuning information parts 52 and 54 are outputted. The command of the tuning information corresponding to DO 2 of the source program 51 is outputted to the tuning information part 52 and the comment corresponding to DO 10 of the source program part 53 is outputted to the tuning information part 54. In case of the information part 54, there is no tuning reference example corresponding to DO 10, so no example is outputted. The comment key word of the comment of the tuning information has no user specification and original source program description format is standard format, so the comment key word of the tuning information is outputted with a standard value.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tuning support for efficiently executing a source program written in a high-level language, and more particularly to a processing method for modifying a source program while referring to tuning information.

[0002]

2. Description of the Related Art The conventional technology is Hitachi Creative Station 3050 HI-UX / WE HI-UX /
WE2 FORTRAN Development Support System FORT /
ASSIST / W Manual / Operation Manual 3050-7-42
0-20 As described on pages 156 to 158,
The source program and the tuning information were displayed in different windows and referenced to modify the source program for tuning.

[0003]

The above-mentioned prior art is intended for tuning work in a window system capable of displaying a plurality of windows at the same time. Therefore, when performing tuning work in a window system in which a plurality of windows cannot be displayed at the same time. , I needed a special editor that could modify the source program while displaying tuning information.

In order to solve the above problems, the present invention has an object to provide a tuning system which can perform a tuning operation without using a special editor in a window system which cannot display a plurality of windows at the same time. To do.

[0005]

[Means for Solving the Problems] In order to solve the above problem, even if a window system cannot display a plurality of windows at the same time by outputting a source program in which tuning information is automatically inserted as a comment in a source program, The problem is solved by referring to the source program and tuning information at the same time with a general-purpose editor, and making corrections for tuning possible.

[0006]

Operation: The tuning support refers to the source file information table or the tuning information table to determine whether to insert tuning information.

While the source program of the source program is input and output line by line, the tuning insertion information table is referred to and the ISN (Interna
l Statement Number: Internal statement number) and tuning information insertion ISN in the tuning information table
If the two match, the execution information, tuning diagnostic message, and the tuning information comment of the tuning reference example are output.

The comment keyword of the tuning information to be output differs depending on the description format (standard format or free format) of the source program. Further, since the keyword can be freely specified by the user, the source program part and the comment part of the tuning information can be easily distinguished.

[0009]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing how to proceed with the program tuning work. Creating tuning information ~ 1 and
In the acquisition of execution information-2, a program for tuning is compiled, executed, or simulated, and analysis information used in the tuning work-3 is generated.
The program performance checks 4 to 4 check the program execution performance while referring to the execution information. Tuning target selection ~ 5 is what part of the loop in the program,
Select whether to tune the block. In the program tuning to 6, the program is tuned by examining the tuning diagnostic message and the tuning reference example. In the confirmation of tuning result to 7, the program is recompiled and executed, and the execution result after tuning correction is confirmed. The present invention relates to program tuning-6.

A detailed process for automatically inserting tuning information as a comment into a source program and performing program tuning will be described below.

FIG. 2 shows the source file information table-1.
Indicates 0. The table corresponds to a source file for inserting a tuning information comment, manages a source file of a source program for inserting tuning information, and a tuning information table pointer for managing tuning information for automatic insertion-12. Is set.

FIG. 3 shows a tuning information table-20.
Indicates. This table exists for the number of pieces of tuning information to be automatically inserted in the source file, and the insertion information management area to manage the ISN of the source program to which the tuning information is automatically inserted, and the tuning information to be automatically inserted. Tuning information text management areas to 22 for managing character strings are set.

FIG. 4 shows a process of automatically inserting tuning information. One line of the source program is input to 30, and it is determined whether there is an input source program to 31. If there is an input source program, output 32 of the input source program is performed. ISN of input source program
And whether the ISNs of the tuning information table match or not is determined to 33. If they match, it is determined whether the tuning information comment keyword is specified by the user ~ 34. If the comment keyword is specified by the user, a character string specified by the user is set as the comment keyword of the tuning information ~ 36, and the comment keyword is added. The comment of the tuning information is output to 37. If the comment keyword is not specified by the user, the standard value character string according to the description format (standard format and free format) of the source program is set as the comment keyword of the tuning information ~ 35, and the comment of the tuning information with the comment keyword added Is output to 37.

FIG. 6 shows the source program 40 of FIG.
The source program to 50 in which the comment of the tuning information is automatically inserted is shown. Source program parts to 51, 53, and 55 of the source program to which comments of tuning information are automatically inserted are included in the source program parts to 51, to 53, and 55.
2 to 43 are output, and the tuning information section to 52 and 5
The comment of the tuning information automatically inserted in 4 is output. The comment of the tuning information corresponding to DO 2 in the source program section-51 is shown in the tuning information section-5.
2 is output. Source Program Department ~ 53 DO 1
A comment of tuning information corresponding to 0 is output to the tuning information section to 54. Tuning information section ~
In the case of 54, since there is no tuning reference example corresponding to DO 10, the tuning reference example is not output.
In addition, since the comment keyword of tuning information does not have user designation 34 and the source source program description format is standard format 35, the comment keyword of tuning information is output with a standard value (* TF).

[0016]

According to the present invention, it is possible to make corrections for tuning while checking both the automatically inserted tuning information comment and the source program, and it is not necessary for the window system to display a plurality of windows simultaneously. Also, the tuning work of the program can be performed without a special editor capable of modifying the source program while displaying the tuning information.
