Abstract

PURPOSE:To attain the instantaneous restart of a program and to improve the debugging efficiency by reading out the memory information and the file information to store them in each storing part and then generating an executing environment necessary for restart of the program. CONSTITUTION:A program 1 is provided together with a storing part 2 which stores the memory information, a storing part 3 which stores the file information, the saved file storing parts 42 and 43, and an execution control part 5. Then the memory and file information are generated wheile the program 1 is carried out with a command given from the part 5. When the program 1 carries out a prescribed address, the part 5 stores both memory and file information in the part 42 and 43 respectively. If a reexecution command is received from an address set in the course of the program 1, the contents of both parts 42 and 43 are read out and the memory and file information are stored in the parts 2 and 3 respectively. Then the execution of the program 1 is restarted in its middle address.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a program re-execution processing system. When the program is debugged, even when the debugging is restarted from the middle address, the program is always started from the first address in order to reproduce the necessary predetermined contents of the main memory and the file.

When resuming debugging from a predetermined address,
It is required that even if the program is started immediately from the target debug restart address without re-executing the bug-corrected program part from the beginning, the same debug environment as when starting the program from the beginning is generated. ing.

2. Description of the Related Art FIG. 6 shows an explanatory diagram of conventional program debugging. In FIG. 6, program 6 is a main memory
61 and the file device 30 are used as program resources, and the memory information 25 and the file information as the program 6 is executed
35 is generated. That is, when the program 6 is executed from step a1 which is an execution start step to a predetermined step ai, the memory information 25 is generated by reading and writing the main memory 61, and the result file obtained by reading and writing the file device 65. Information 35 is generated.

When the program 6 is restarted from step as following step ai, the memory information generated by the program 6 executing steps a1 to ai
25 and file information 35 are required as a program environment for program restart.

Therefore, in the conventional method, even when the debugging is restarted from the step as, the program 6 is executed again from the first step a1 to the step ai so that the memory information for the debugging after the step as is executed. 25 and file information 35 are generated to reproduce the program environment required for program debugging.

[0006]

When the program is restarted from a step in the middle as described above, it is necessary to start the program from the first step each time it is restarted to generate a necessary program environment. For this reason, when the program scale increases, there is a problem in that it takes more time to generate the program environment and the debugging efficiency is reduced.

An object of the present invention is to improve the debugging efficiency of a program by allowing the program to be restarted immediately without running the program from the first step when the program is restarted from a predetermined step.

FIG. 1 is a block diagram showing the principle of the present invention. It has a program 1, a storage unit 2 for storing memory information, a storage unit 3 for storing file information, save file storage units 42, 43, and an execution management unit 5, and receives a command from the execution management unit 5. Memory information and file information are generated in the process of executing the program based on the program. When the program 1 executes a predetermined address, the execution management unit 5 saves the memory information and the file information in the save file storage units 42 and 43.
When there is a re-execution command from an address in the middle of the program 1, the contents of the save file storage units 42 and 43 are read to generate memory information and file information in the storage units 2 and 3, respectively. Execution of the program 1 is restarted from the midway address.

[0009]

When the program 1 starts the program 1 and the program 1 executes a predetermined address, the execution management unit 5 saves the memory information and the file information 3 generated in the storage units 42, 43 by the save file 42, respectively. Save to 43, and if there is a re-execution command from an address in the middle of the program 1,
By reading the memory information 2 and the file information 3 saved in the save file storage units 42, 43 and generating them in the storage units 2, 3 respectively, and by generating the execution environment necessary for restarting the program 1, the program can be executed. Debugging can be restarted without traveling from the first step to the address on the way, and improvement in debugging efficiency can be expected.

EXAMPLE FIG. 2 shows a system configuration diagram of an example. Figure 2
The system shown in FIG. 1 includes an execution management unit 5, an application program (hereinafter abbreviated as APL) 10, a memory area 15 having a storage unit 2, a computer processor 20 having a restart information unit 22, and a display device (screen). 21) (which has a display unit and an input unit for operation commands, etc.), a file device 30 which has a storage unit 3, and an external storage device 4 which has save file storage units 42 and 43.

The APL 10 is activated by the execution management unit 5, stores the memory information generated in the program execution process in the storage unit 2 of the memory area 15, and stores the file information generated in the program execution process in the storage unit 3 of the file device 30. Store.

When the APL 10 executes a predetermined address, the execution management unit (5) saves the contents of the storage unit 2 and the contents of the storage unit 3 to the save file storage units (42, 43), respectively. Executing the program of FIG. 3 with the memory information (Ci) generated in the storage unit 2 and the file information (Fi) generated in the storage unit 3 in the process of the APL 10 executing the program step from the start address of the program. And memory information and file information.

In FIG. 3, the APL 10 sequentially executes steps from the program start step S1 to step Si.
The memory information and the file information when executing is indicated by Ci and Fi, respectively.

Next, a description will be given of the case where the program debugging up to the step Si of the APL10 is completed and the execution of the program APL10 is restarted from the step (step Sx) next to the step Si. This is performed with reference to the preparation procedure and the explanatory diagram of the restart of the program in FIG.

In FIG. 4, the operator takes the processing steps.
The program restart command with the address information (mi) for restarting debugging at 80 as a parameter is displayed on the display device.
Input from 21 key input section (not shown). In process step 81, the execution management unit 5 reads the address information (mi) and sets an interrupt flag in the program (step Si) of the APL10 stored in correspondence with the address information (mi). The interrupt flag is set so that an interrupt is issued to the execution management unit 5 when the program of step Si is executed.

In step 82, the execution management unit 5 waits for the operator to input a response indicating whether or not the program has started. When the operator inputs a program start command from the display device 21, in step 83, the execution management unit 5 sets the APL
10 is started from the execution start address, and a predetermined interrupt from APL10 is monitored.

When the activated APL 10 executes the program of step Si in which the interrupt flag is set, a program interrupt is issued to the execution management unit 5. In step 84, the execution management unit 5 that has detected the interruption reads the contents (memory information Ci) of the storage unit 2 and saves it in the save file storage unit 42 of the external storage device 4. Similarly, the content (file information Fi) of the storage unit 3 is read from the file device 30 and saved in the save file storage unit 43 of the external storage device 4.

In process step 85, the execution management unit 5 registers in the restart information unit 22 the address information (address mx) of the next step (Step Sx) after the step Si and the file names of the save file storage units 42 and 43. A message indicating that the program is ready for restart is displayed at processing step 86.
Display on 21.

Next, when activating the APL 10 which is ready to be restarted, the operator inputs a restart command for the APL 10 from the display device 21 in processing step 91 of FIG. When the restart command is input, the execution management unit 5 checks the presence / absence of registration information in the restart information unit 22 in processing step 92.

If the registration information is not stored in the restart information section 22, the APL 10 is started from the program starting step S1 in the processing step 95. If the registration information is stored in the restart information section 22, the execution management section 5
The contents of the save file storage unit 42 are read from the external storage device 4 and written to the storage unit 2 of the memory area 15 (memory information C
i), the contents of the saved file storage unit 43 are read and written in the storage unit 3 of the file device 30 (file information Fi
Restoration).

With the above processing, the environment for resuming the program is completed, and the execution management unit 5 executes APL10 in step Sx in processing step 94.
Start from.

[0022]

The execution management unit 5 reads the memory information and file information necessary for restarting the execution of the program 1 from a predetermined address from the save file storage units 42, 43 of the external storage device 4, and retrieves each of them. By restoring to the storage units 2 and 3, it is possible to debug from the debug restart address without running the program 1 from the beginning.
