Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a debugger, and more particularly to a debugger which uses a command program already generated as one command.

[0002]

2. Description of the Related Art In a conventional debugger, a user sets a program stop position in the debugger, stops the program at a certain point, and displays arbitrary memory contents at this point, or The contents of the registers and all the registers are displayed, the behavior of the created program is traced, and the location of the error is limited. These debugging operations are performed by interactively giving commands to the debugger in units of functions.

[0003]

In the above-mentioned conventional debugger, since the user performs the debugging work only by sequentially giving the commands of a single function unit, for example, the execution of the program is stopped at a certain stop position. If you want to repeat the work of displaying the contents of the memory, or if you want to display the contents of the register when the contents of the memory reach a specific value, you can enter the necessary commands one after another and proceed with the debugging work. I had to display the memory and check the contents of the registers. This was true even if I wanted to do the same thing again to debug the program. In addition, after modifying the program created by the user, to confirm whether this program is operating correctly, even if the user wants to perform the same processing as before for the debugger, the user should follow the same procedure to debug. I had to repeat typing commands. In other words, if it is necessary to repeat the same series of instructions to the debugger as before, you have to repeat the exact same instructions as before and input them again, which will be troublesome twice and debugging will take time. There is a problem.

The object of the present invention is to provide a series of debug procedures
It is to provide a debugger that can be easily and repeatedly executed as a command and that makes debugging work simple and efficient.

DISCLOSURE OF THE INVENTION A debugger of the present invention is a command control for analyzing various commands input by the user and outputting control information in the debugger for interactively exchanging information with the user for program debugging. Means, command program generating means for receiving a control information from the command control means that analyzes a program creating command input by the user, and generating a command indicating a debugging procedure as a command program, and executing a program input by the user Command program processing means for receiving control information from the command control means that has analyzed the command and analyzing and processing the command program indicating the debug procedure, and externally provided when executing the command program connected to the command program processing means Available user programs A structure having a debugging function executing means having a function of.

In the debugger of the present invention, the debug function executing means directly receives the control information from the command control means which analyzes the debug command input by the user, and executes the debugging by using the user program provided outside. It may have a function.

The debugger of the present invention may be connected to an external command program data file for saving the command program generated by the command program generating means.

[0008]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention.

The debugger 1 of the present invention includes command control means 2 for analyzing various commands input by the user and outputting control information, and control information from the command control means 2 for analyzing the program creation command input by the user. Command command generating means 3 for generating a command indicating a debugging procedure as a command program and command control means 2 for analyzing a program execution command input by a user, and analyzing a command program indicating a debugging procedure. It has a command program processing means 4 for executing processing, and a debug function executing means 5 connected to the command program processing means 4 and having a function for enabling the use of a user program 6 provided outside when executing the command program Furthermore, the command program generating means 3 generates the For saving the command program, and is connected to the command program data file 7 provided outside.

FIG. 2 is a block diagram showing the function of the command generating means.

In order to create a command program in which a series of debugging procedures that the user wants to perform for the debugging means is entered, a program creation command is input to the command control means 2 and the command program creation means 3 is entered. Transfer control to. The command program generating means 2 includes
Editing means 8 for the command program as shown
There are a saving means 9 and an input means 10. The user can create a command program in which a series of debugging procedures are put together by the editing means 8. Further, the created command program can be left in the external medium as the command program file 7 by the saving means 9 and the input means 10, or can be read from the external medium and used as the command program again.

Next, the operation of executing the command program will be described.

To execute the command program created in this way, a program execution command is input to the command control means 2 and control is transferred to the command program processing means 4.

FIG. 3 is a flow chart of the operation of the command program processing means.

When it is started, first, the specified command program is read, syntax analysis is performed, and scanning is performed for an illegal command program (step 101).
Next, in order to actually execute the analyzed command program, the command program is converted into an internal code at each step (step 102). Further, this conversion step may be performed simultaneously with the scanning step 101.
The conversion to the internal code is performed in order to simplify the processing at the time of execution and improve efficiency. Next, the internal codes are sequentially taken out (step 103), and it is judged whether or not the end condition is satisfied (step 104). If the end condition is satisfied, the program executing means is ended. If not satisfied, the internal code taken out is analyzed (step 105), and it is determined whether this internal code is the execution of the debug command (step 106).
If it is executed, the control is transferred to the debug function executing means (step 107), and if it is not executed, internal code processing such as condition judgment, branching and substitution is performed by the internal code (step 1).
08), the process returns to step 103 again to continue the process.

As described above, the command program processing means 4 analyzes and executes a series of debug commands, so that it appears to the user that one debug command (program) is being executed. Of course, for the same command program, it is also possible to execute the command program data file 7 if it already exists in the memory without reading the command program data file 7 each time.

The user can use the debug command to
It is also possible to use the debug function executing means 5 directly from the command control unit 2.

[0019]

As described above, the present invention comprises the command control means for analyzing various commands input by the user and outputting the control information, and the command control means for analyzing the program creation command input by the user. Command program generating means for receiving a command indicating a debugging procedure as a command program by receiving control information of the above and command command analyzing means for analyzing a program execution command input by the user and analyzing a command program indicating a debugging procedure By having a command program processing means for executing the processing and a debug function executing means connected to the command program processing means and capable of using a user program provided outside when executing the command program. Simplifies the debugging procedure of Also make it possible to carry out repeated many times, the effect is there that it becomes possible to the good things simple and efficient debugging work.
