Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to the evaluation of program execution performance in a computer system, and in particular, to performance information generation of a target program generation unit of a language processing program that converts a source program into a target program. Regarding the method.

[Conventional technology]

In order to obtain execution performance information in conventional computer systems, the source program is translated into the target program, and then converted into an executable format, and then trap instructions are embedded at the necessary points in the executable program and executed to trap the program. The actual CPU time between points had to be measured. Furthermore, there was no means to provide execution performance information during translation.

[Problem to be solved by the invention]

In the conventional method described above, there is no means to generate execution performance information during translation processing, and after translation processing, the program is converted into an executable format, an execution environment is created, and a trap instruction is embedded at each point in the program to be measured, and the program is actually executed. It is necessary to measure the CPU time from trap point to trap point, which requires a great deal of effort to obtain program execution performance information and improve execution performance, which is inefficient.

Furthermore, the measurable range is only between the trap points, making it extremely difficult to measure the instruction unit of the source program.

Therefore, an object of the present invention is to generate execution performance information for each instruction of a source program when translating a source program by providing CPU performance information, object code analysis means, and object code weighting means in the target program generation section of a language translation program. , by providing execution performance information for each instruction in the source program using only translation,
The purpose is to reduce the effort required to obtain program execution performance information and increase the efficiency of program performance improvement.

[Means to solve the problem]

The simplified execution performance information generation method of the present invention is provided in a language processing system that inputs a base program and generates a target program. CPU performance information consisting of a correspondence table of each instruction code for each hardware model and CPU time for each instruction code, and an object that searches and generates CPtJ performance information from hardware instructions analyzed and classified by object code analysis means. The object code weighting means weights the execution time of the code and generates a list of execution performance information for each instruction of the source program written by the user.

〔Example〕

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

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. In FIG. 1, the simplified execution performance information generation method of this embodiment inputs the object code generated by the target program generation section of the language processing program that converts the source program into the target program, and then analyzes it to determine the pattern of hardware instructions. The object code analysis means 1 classifies and classifies the information into the CPU performance information 2, which consists of a correspondence table of each instruction code for each hardware model and the CPU time for each instruction code registered in advance, and the object code analysis means 1. Comprised of an object code weighting means 3 that searches CPU performance information 2 from hardware instructions, weights the execution time of the generated object code, and generates an execution performance information list 4 for each instruction of the source program written by the user. be done.

FIG. 2 is a flowchart showing the flow of the process shown in FIG. In FIG. 2, in step 21, the target program generated by the target program generation section of the language processing program is first input. Here, as an example, the source program MOVE
Consider the case where instructions are expanded to the following target program.

MOVF A To B.

LOAD BRI ADDR(A)LOAD
BH3ADDR (B) LOAD GRI LENGTH (B) MVCA
(BRI) B (BH3, GRI) Next step 2
Classify and analyze the target program input in step 2. In this example, it is analyzed as: ■LOAD instruction pace register specification ■LOAD instruction pace register specification ■LOAD instruction general register specification ■MVC instruction memory length GR specification.

Next, in step 23, CPU performance information is retrieved from the analyzed results to determine the CPU execution time of each target program.

In this example, assume that the following execution time is found as a result of the search.

■Instruction 5 microseconds ■Instruction 5 microseconds ■instruction 3 microsecond ■instruction 15 microseconds Finally, in step 24, the execution performance information for the MOVE instruction is displayed as the total execution performance of 5+5+3+15=28 microseconds. do.

The above is an explanation of the processing flow of this embodiment. It can be seen from this process flow that execution performance information can be generated for each instruction of a source program during translation using this method.

〔Effect of the invention〕

As explained above, by providing CPU performance information, object code analysis means, and object code weighting means in the target program generation section of the language translation program, execution performance information is generated for each instruction of the source program during translation of the source program. By providing execution performance information for each instruction of a source program through translation alone, the effort required to obtain program execution performance information can be reduced and the efficiency of program performance improvement can be increased.
