Abstract

PURPOSE:To shorten a debugging processing by counting the number for calling a debugging program and executing a program to be debugged from the next address of a prescribed address subsequently to stored contents without executing the debugging program when the called number does not coincide with the inputted number. CONSTITUTION:The contents of the prescribed address inputted by the input means 1 of the program to be debugged are stored in a holding means 12, an instruction for calling the debugging program is written in the address, the called number of the debugging program according to the execution of the program to be debugged is counted by a counting means 11, when the called number does not coincide with the inputted number, the debugging program is not executed but the program to be debugged is executed from the next address of the prescribed address subsequently to the contents stored in the holding means 12. Thereby, the execution of the program to be debugged is not interrupted at the contents of a register or a memory at the prescribed position of the program are grasped to continue the debugging processing.

Description

Detailed Description of the Invention A) Industrial application field Misfire 811 is 1 as a computer development support system.
This article relates to a 0gram debugging method.

[Background Art] Conventionally, debugging a program involves running the program to be debugged, stopping at a desired point, extracting the contents of a specified register or memory, and looking at the contents. (For example, the opening of the neck was 1m55-15
See Publication No. 4636.

By the way, if you want to proceed with the debugging process by looking at the 6 valleys of the specified register Rurui Mesori when this program is executed a specified number of times, this debugged program It was necessary for the operator to set a breakpoint at a predetermined location in the debugged program, run the program to be debugged, count the number of times the debugged program was stopped, stop the program until the predetermined number of times was reached, and then return the program.

C) Problems that the invention solves and F For the operator, it is a very troublesome task to count the number of times a program has stopped, or to restart a friend program after stopping it, and the program is interrupted every time. This will have a negative impact on other programs and will not allow for accurate debugging, and will also require a large amount of time for debugging. , a given iterative darogram is executed without interrupting the execution of the program to be debugged, n, and the given program v! It provides debugging information that allows the debugging process to be completed by grasping the contents of the register f memory in Bffr.

2] The ninth means for determining the time interval is an input means for inputting the predetermined address of the program to be debugged and the number of times, and input means for manually setting the predetermined address of the program to be debugged. Inside'4t - evacuate 2
and a counting means for counting the number of times the debug program has been called. An iF is inserted into the instruction to call the debug program at the address, and the counting means counts the number of times the debug program is called by executing the temporary debug program. FIFPs that do not execute the debugging program do not execute the debugging program, but instead refer to the contents stored in the holding means at the address next to the specified address. .

e) While the number of inputs is counted by the action counting means, the debugged program is executed multiple times without relaying.
, when the temporary debug program is executed the same number of times as the number of inputs, the execution of the debug program is stopped at the predetermined location of the input fL7H address of the program to be debugged, and the debugging process proceeds. .

to) Example (IJ is connected to the I[I control circuit (3) via the I10 interface (2J) on the 11?-board as an input means. (4) is the C1 (T 11g4 is displayed together with the control circuit (3) in the CI (T controller (5)). (6) is the #Il memory in which the debugged program is stored, and (7) is the debugged program. An auxiliary 11tlJg1 circuit (8) is a control circuit (3)'(D a second memory in which a control program and a debug program are stored, (9J(1(I)
The keyboard (1) is input manually and the specified address and @J
The first and second registers store numbers, uIJ is a counter that counts the number of times the debug program is called,
C4 is a save V register for holding the contents of the PJt redundant address inputted from the current board (υ).

Such a tc position will be explained with reference to FIG. 42 and 70-t yard in FIG. Note that the program to be debugged stored in the first memory (6) is i! of address A at the end. It is executed in a loop after r.

First, after preparing the program to be debugged in the first memory (6J), from the board (υ), the specified address A of the program to be debugged suitable for debugging and the number of times the program to be debugged has been executed. Input whether to proceed with the depacking process or the number of times n.The input address A and the number of times n are stored in the d2 register Ql.
Zanru (81).劃Ijl t! 21 jli+3 (
3J holds the contents of address A specified in the first register (9) of the debugged program of 6J yen in t:A save register 4, and further stores 411/register (tt in 91).
Replace the command (CALL j)IjG) to call debug program
82). The +Vt+ control circuit (3) is connected to the auxiliary 5aute circuit (7) to debug the program to be debugged.
It causes the debug program to run in memory (6) ($3).

Now, when the contents of address A shown in register (9) are not processed, the debug program is called (84).
). Here, the control circuit (3) counts the number of times the debug program is called from a counter (111Vc) and
Compare the number of times n stored in the 1IE2 register with the number of times n is stored in the 1IE2 register. When the two values do not match, the control circuit (3) saves n to the address A of the program to be debugged indicated by the register n and stores it in the save register 0.
Write the contents of the file and retry from address A without running the debug program in the memory (8) circle! The I control circuit (7) is caused to continue executing the temporary debug program (S6).

If both values match, then! The II@1 circuit (37 executes the debug program as is) performs processing such as outputting the contents of predetermined registers and memory to t-CRT (43) and storing them in other memory ranges (not shown).

After the execution of the debug program is finished, the control circuit (
37 is assistance! The lJ control circuit (71) is delayed and executes 8 of the registers, and then the program to be debugged is executed again at the address after address A of the program to be debugged (S8).

Therefore, when the program to be debugged is executed multiple times, if you want to know the contents of a specified register or memory at the time of the multiple executions, you can check the number of times in advance. By inputting from , it becomes possible to reap the contents of the Q predetermined register f memory after the debugged program has been executed for the desired number of days without stopping the execution of the program to be debugged.

g) Effects of the Invention As is clear from the above description, the present invention allows debugging when the depandered program t is executed a predetermined number of times without interrupting the temporary debugging program once. It is also possible for the operator to count the number of pans. For this reason, the operator must stop the debug program toL.
This eliminates the hassle of having to do e-copying, and the time required for debugging can be shortened. Furthermore, interruption of the program to be debugged does not affect other programs, making it possible to perform accurate debugging.
