Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used in a link processing device of an electronic computer. In particular, the present invention relates to a link processing device of a plurality of compiling units of a computer language capable of performing split compilation.

[0002]

2. Description of the Related Art Conventionally, a link processor includes a compile unit prepared by compiling a program created by a user and a system compile unit library prepared for a system having an input / output function and various utility functions. It was general that the processing format was such that they were combined and output the load module.

Such a system compile unit library and a user compile unit library as a utility created by the user are stored as an archive format or a library format file, and the link processing device executes the link processing of the user compile unit library with these files. I was going as a target.

[0004]

However, in such a conventional link processing device, the library is used in the case of a language that is used in various fields or in a language that is used to perform various processes. Has become huge, and it takes a long time to search and access the compile unit necessary for the link processing, and there is a problem that the processing time of the entire link processing increases. This has the same problem when the user accumulates the utility.

However, it is rare to use all the compilation units of a huge library evenly, and the compilation units that are actually frequently linked are only a few of them. Therefore, it can be said that much of the time required for the linking process is used to skip the infrequently used compilation unit in order to search for and access the desired compilation unit in the library.

The present invention solves the above problems.
An object of the present invention is to provide a link processing device capable of increasing the link processing speed without imposing a burden on the user.

The control unit updates the use frequency information stored in the dictionary unit based on the use frequency information of the input name selected by the selection unit by the frequency updating unit and notifies the rearrangement unit, and the rearrangement unit described above. The contents of the system compile unit library and the user compile unit library are rearranged so as to increase the selection speed based on the updated usage frequency information.

As described above, the link processing speed can be increased without burdening the user.

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of a link processing device according to an embodiment of the present invention.

In FIG. 1, the link processing apparatus includes a dictionary section 30 for storing input name information of a plurality of compilation units and usage frequency information thereof, a system compilation unit library 50, a user compilation unit library 60, and a control section 40. And the control unit 40 inputs the user compiling unit 10 from the user and the dictionary unit 3
The selection unit 41 that selects the input name of one or more compile units corresponding to the input name used by the user compile unit 10 from 0, and the compile unit of the input name selected by the selection unit 41 is used as the system compile unit library 50 and the user. It includes a reading unit 42 for reading from the compile unit library 60, a combining unit 44 for combining the user compile unit from the selecting unit 41 and the compile unit from the reading unit, and outputting as the load module 20.

A feature of the present invention is that the control unit 40 updates and rearranges the use frequency information stored in the dictionary unit 30 based on the use frequency information of the input name selected by the selecting unit 41. The unit 45 includes a frequency updating unit 43 for notifying the unit 45, and a rearrangement unit 45 for rearranging the contents of the system compile unit library 50 and the user compile unit library 60 so as to increase the selection speed based on the updated use frequency information. It is characterized by

The system compile unit library 50 is composed of a predetermined compile unit including an input / output unit and a utility unit, and the user compile unit library 60 is a compile unit in which a program created by a user is compiled.

Further, the reordering unit 45 includes means for moving a frequently used compilation unit to the head position of the system compilation unit library 50 and the user compilation unit library 60 when the file is an archive file.

The rearrangement unit 45 includes means for allocating the most frequently used compile unit to the system compile unit library 50 and the user compile unit library 60 when the file is a semiconductor disk device.

The operation of the link processing device having such a configuration will be described. FIG. 2 is a flowchart showing the operation of the link processing device of the present invention.

In FIG. 1 and FIG. 2, the selection unit 41 of the control unit 40 inputs the user compiling unit 10, extracts the input name required for linking the user compiling unit 10, and corresponds to the input name from the dictionary unit 30. The library compile unit name is input, and the user compile unit input from the user compile unit 10 is output as it is to the combining unit 44 (S1, S2).

Further, the selection unit 41 sends the library compilation unit name corresponding to the input name retrieved from the dictionary unit 30 to the reading unit 42, and the reading unit 42 selects the compilation unit corresponding to the user compilation unit name as the system compilation unit. The library 50 and the user compile unit library 60 are read (S3) and sent to the combining unit 44. The combining unit 44 combines the user compile unit from the selecting unit 41 and the compile unit from the reading unit 42, and loads the load module 20. (S4).

On the other hand, in the selection unit 41, the library compilation unit name retrieved from the dictionary unit 30 is used as the frequency updating unit 4
Send to 3. The frequency update unit 43 updates the usage frequency information of each compile unit of the dictionary unit 30 and sends it to the rearrangement unit 45 (S5). Based on the frequency information, the rearrangement unit 45 performs a rearrangement process on the system compilation unit library 50 and the user compilation unit library 60 to a storage area in which a frequently used compilation unit can be accessed at higher speed (S).
6).

The rearrangement of the frequently used compilation units to the storage area which can be accessed at a higher speed may be, specifically, the movement to the beginning of the file in the archive file. By this processing, the time for positioning the file from the beginning is saved, and the time required for the link processing is shortened. This is more effective in a processing system that is weak in dynamic file positioning.

As another method, the access time is faster than that of an ordinary file,
It can be allocated to a semiconductor disk device which is a very expensive resource. In this case, the capacity of the semiconductor disk device is small, and the device can be effectively used by allocating all of the system compile unit library and the user compile unit library.

[0025]

As described above, the present invention has an excellent effect that the link processing speed can be increased without burdening the user.
