Abstract

PURPOSE:To effectively and smoothly perform the tasks in a debugging process by previously setting the debugging instruction information in an instruction information store area. CONSTITUTION:An instruction information store area 2 stores the debugging instruction information at a debugging point set previously at a debugging object program. A debug executing part 4 carries out various dubugging processes based on the debugging instruction information stored in the area 2. A debug control part 3 retrieves the area 2 to take out the debugging instruction information at the corresponding debugging point when the debugging object program reaches the debugging point. Then the part 3 asks the part 4 to perform the debugging process related to the corresponding debugging instruction information. Thus the tasks in the debugging process are effectively carried out.

The debugging method of this embodiment allows control from the debugging point (debugging point statically set in advance by the program developer) of the program (see Figure 3; the program to be debugged in the debugging method of this embodiment). A debug execution control unit 1 (instruction information storage area 2; debug control unit 3 and debug execution unit 4 are under the control of this debug execution control unit 1) that controls the execution of debugging processing) and debug instructions at debug points Instruction information storage area 2 for storing information (Debug instruction information is created and stored in advance by the program developer. In this case, it is possible to store multiple pieces of debug instruction information for any debug point. ), a debug control unit 3 that searches the instruction information storage area 2 to retrieve predetermined debug instruction information and requests the debug execution unit 4 to perform debugging processing based on the debug instruction information, and A debug execution unit 4 that executes debugging processing, a terminal 10 that is a terminal in a conversation processing system to which the debugging method of this embodiment is applied, and a trace result file 11 that outputs trace results in the process of debugging processing. It is composed of:

The debug execution unit 4 includes a batch execution unit 5 that performs punch processing to rewrite the contents of a memory (not shown), and a terminal IO after executing other debug processing based on debug instruction information.
Based on the terminal input/output execution unit 6 which makes it possible to input debug instruction commands, and the trace range instruction and output light instruction (instruction to specify the terminal 10 or the trace result file 11 as the output light of the trace result). The debug point passage history execution unit 8 collects a debug point passage history, and the abort execution unit 9 aborts a program and collects a memory dump. In addition to the above-mentioned execution units, the execution unit 4 may include execution units corresponding to various other debugging processes).

Referring to FIG. 2, the processing of the debug control unit 3 includes a debug instruction information search step 21, a debug instruction information presence/absence determination step 22, and a debug processing request step 23.

FIG. 3 shows an example of a program to which the debugging method of the present embodiment is applied and debugging is performed, and the configuration of the instruction information storage area 2 for the program (configuration of the debug knob instruction information at the debugging point of the program). FIG.

This program has five debug points set (debug points are pre-coded and statically set at arbitrary points), and the labels (debug point labels) at these debug points are rAJ, rBJ
, rcJ, and rDJ (there are two debug points related to debug point label A).

Each entry in the instruction information storage area 2 stores debug instruction information for debug knob bells A, D, and C (debug instruction information for debug point label B is not stored. All debug points (There is no need to store debug instruction information for

Each debug instruction information includes a debug point label, a next instruction information pointer (a pointer pointing to the next debug instruction information entry), instruction bit information, and instruction information.

The instruction bit information includes each instruction bit (debug point passage history instruction bit, trace (terminal) instruction bit, trace (file) instruction bit) that corresponds to each debug process to perform which debug process.

terminal input/output instruction bits, abort instruction vias), etc.) (for example, indicates that debug processing corresponding to the instruction bit for which rlJ is set is to be performed)
, the position of each bit indicates the priority between each debug process (this allows an abort instruction or a command to the terminal 10 to be issued after collection of debug point passage history, batch processing, trace collection, etc. Instructions that enable human output (terminal input/output instructions, etc.) are guaranteed to be executed).

The instruction information has information indicating the contents of punch instructions, trace instructions, etc., and includes a batch address, a batch image, a trace disclosure address, a trace end address, etc. (rPJ in FIG. 3 indicates the punch instruction. (the "T" indicates a trace instruction).

Next, the operation of the debugging method of this embodiment configured as described above will be explained.

The debug control unit 3 is activated by the debug execution control unit 1 to which control is passed from the debug point of the program (for example, the debug point of the debug point A in FIG. 3). Control by section 1 is not mentioned).

The debug control unit 3 performs the following processing.

First, the instruction information storage area 2 is searched using the current debug point label (debug point label A) as a key (step 21).

In this search, it is determined whether debug instruction information for the current debug point label exists (step 22
).

If it is determined in this judgment that there is no debug instruction information for the current debug point, execution of the program is resumed without instructing the debug process (requesting the debug execution unit 4 to perform the debug process).

If debug instruction information exists for the current debug point label in step 22, the debug process related to the debug instruction information (if the debug instruction information includes instructions regarding multiple debug processes, one of the debug process instructions) The debug execution unit 4 is requested to execute (process) (step 23).

Next, it is determined whether there is any remaining debugging instruction information (instructions related to unfinished debugging processing when a plurality of instructions related to debugging processing exist in the debugging instruction information) (step 24).

If the rest of the debug instruction information does not exist in this judgment,
Resume program execution.

If it is determined in step 24 that there is any remaining debugging instruction information, control is returned to step 23 (thus, the above-described processing is repeated until all debugging processing related to the debugging instruction information is completed).

The debug execution unit 4 receives a request for debug processing from the debug control unit 3 (see step 23 in FIG. 2), and the punch execution unit 4
．． Terminal input/output execution unit6. Trace execution unit 7. The debugging point passage history execution unit 8 or the abort execution unit 9 is activated to execute the respective debugging processes.

Here, the terminal input/output execution unit 6 puts the terminal 10 in a state where a dehasog instruction command can be input after executing other debug processing, and the trace execution unit 7 performs a trace operation using the terminal 10 or the trace result file 11 as the output light. Collect.

〔Effect of the invention〕

As explained above, the present invention provides dehasing instruction information by setting in advance in the instruction information storage area, etc.
It is now possible to instruct many debugging processes such as punch processing (memory rewriting), collection of traces with a specified trace range, and abort instructions without having to input commands from the terminal at the debugging point of the program to be debugged. It goes without saying that it is possible to instruct the collection of the passage history), automatically check the operation of the program to be debugged, etc., and prevent mistakes in address specification during debug processing for the program to be debugged.
