DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing a configuration of a dynamic characteristic analysis mechanism 3 to which a dynamic characteristic analysis information acquisition method of a specific portion according to an embodiment of the present invention is applied. The dynamic characteristic analysis mechanism 3 includes a program structure analysis processing unit 31, call relation information 31a, and an analysis target module determination processing unit 32, and the source program 1 and
The analysis target information 2 specifying the analysis target module of the dynamic characteristic is input, and the dynamic characteristic analysis information 4 is output.

FIG. 2 is a diagram showing an example of the program structure of the source program 1. The source program 1 is composed of modules A, B, C, D, E and F.
Module A calls modules B, D and C,
Module B calls modules C and D, and module C calls modules E and F.

FIG. 3 is a diagram showing an example of calling relationship information 31a of the source program 1 shown in FIG. The call relationship information 31a includes a plurality of entries of a module name and a module name called by the module. However, if there is no module name to be called by the module, information to that effect is registered in the module name to be called.

Next, the operation of the dynamic characteristic analysis information acquisition system of the specific portion of the present embodiment thus constructed will be described based on the program structure of the source program 1 shown in FIG.

When the module A of the source program 1 is input, the program structure analysis processing means 31 of the dynamic characteristic analysis mechanism 3 retrieves the module names B, D and C called from the module A, and from the module name A and from there. The called module names B, D and C are registered in the calling relationship information 31a.

Next, the program structure analysis processing means 31
When module B is input, searches for module names C and D called from module B, and similarly registers module name B and module names C and D in call relationship information 31a.

Subsequently, the program structure analysis processing means 31
When the module C is input, searches for the module names E and F called from the module C, and similarly registers the module name C and the module names E and F in the call relationship information 31a.

Next, the program structure analysis processing means 31
When the module D is input, the module retrieves the module name called from the module D. However, since the module D does not include the module call, the module name D and the information indicating that the calling module does not exist are called relationship information 31.
Register with a.

Similarly, the program structure analysis processing means 31
Retrieves the module name called from the modules E and F, but since the modules E and F do not include the module call, the module names E and F and the information indicating that there is no calling module are called relation information 31a.
To register respectively.

The program structure analysis processing means 31 terminates the processing when the analysis of the calling relationship is completed for all the modules A, B, C, D, E and F of the source program 1.

Upper module name B for dynamic characteristic analysis
When the analysis target information 2 designated by is input, the analysis target module determination processing unit 32 sets the module B as the analysis target module group and searches for the module name B from the call relationship information 31a.

Next, the analysis target module determination processing means 3
2 refers to the call relation information 31a of the module B,
Since it is found that the module B calls the modules C and D, the modules C and D are added to the analysis target module group.

Subsequently, the analysis target module determination processing means 32 processes C and D added to the analysis target module group in the same manner as the module B.

Since the module C calls the modules E and F, the analysis target module determination processing means 3
2 adds modules E and F to the analysis target module group.

Since the module D does not include a module call, the analysis target module determination processing means 32
Does not add the module to the analysis target module group.

Subsequently, the analysis target module determination processing means 32 similarly processes the modules E and F newly added to the analysis target module group, but the modules E and F do not include a module call. Therefore, do not add the module to the analysis target module group.

As a result of searching the calling module names for all the modules B, C, D, E and F registered in the analysis target module group, the analysis target module determination processing means 32 determines that the modules B, C, D are included. , E and F are determined as the module group to be analyzed.

Then, the dynamic characteristic analyzing mechanism 3 dynamically sets each module B, C, D, E and F of the analysis target module group determined by the analysis target module determination processing means 32 as the analysis target of the dynamic characteristics. Characteristic analysis processing is performed, and dynamic characteristic analysis information 4 for each module B, C, D, E and F is output.

[0027]

As described above, according to the present invention, the program structure analysis processing means and the analysis target module determination processing means are provided, and the analysis target module group is determined after the module calling relation in the source program is analyzed. By doing so, when the user specifies the module to be analyzed in the program, the module called from that module is searched and automatically specified as the analysis target of the dynamic characteristics, so the user can analyze the static characteristics of the program. There is an effect that the dynamic characteristic analysis information of a specific portion can be collected without performing the analysis and designating the module to be analyzed.
