Description

  The present invention relates to a program development support system and a program development support method for supporting program development.

  In a program development support system that creates an executable program by creating and inputting specification data describing the software specifications, refer to the line number displayed in the specification data and specify that line number in the debugger. By doing so, it is possible to verify (debug) the executable file.

  However, when the object file that constitutes the executable file is created in the object optimization mode of the compile process, the object of a part of the line numbers does not exist by the optimization process. For this reason, even if the line number displayed in the specification data is referred to and the line number is specified by the debugger, the line number does not exist, so that desired debugging cannot be performed.

Therefore, when the optimization process is performed on the source program, a method of inserting the optimization process information into the output text file has been considered (see, for example, Patent Document 1). As a result, information on optimization processing is displayed, and program verification is facilitated.
Japanese Patent Laid-Open No. 08-063369

  However, in the above-described method, the display / non-display of the optimization information is discriminated and displayed for one line in the specified text format. Therefore, there is a problem that it is difficult to display the optimization process information for the entire specification data and it is difficult to visually determine the contents of the optimization process on the specification data.

Debugging can be performed efficiently.

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

  FIG. 1 is a diagram showing an example of a connection form of apparatuses to which the program development support system of the present invention is applied.

  In this connection form, the terminal 100 and the host 300 are connected via the network 200.

  The terminal 100 is a development terminal for developing a program. The worker inputs the specification data into the terminal 100 and transmits the input specification data to the host 300 via the network 200. In addition, debug information of a program transmitted from the host 300 via the network 200 is received and displayed.

The execution format file database 112, the debug information file database 114 on the host, and the debug file database 116 on the terminal are provided in a device (not shown) connected to the network 200 other than the terminal 100 and the host 300. Alternatively, all of these databases may be provided in the terminal 100 or the host 300.

  The specification creation processing unit 101 uses the editor on the terminal 100 to create a specification file based on the specification data input by the operator. The method for creating this specification file is the same as a general method. The created specification file is stored in the specification file database 102 on the terminal.

  FIG. 3 is a diagram showing an example of the specification file stored in the specification file database 102 on the terminal shown in FIG.

  As shown in FIG. 3, the specification file 21 stored in the specification file database 102 on the terminal is such that a specification page, a line number in the specification, and text data as contents are associated with each other. .

  For example, the specification page “1”, the line number “3” in the specification, and the text “edited product item” are associated with each other. This indicates that “edited item” is described in the first line of the first page of the specification data. The same applies to other associations.

  The communication processing unit 103 reads the specification file stored in the specification file database 102 on the terminal and transmits it to the host 300 via the network 200.

  The specification file database 104 on the host stores the specification file transmitted from the communication processing unit 103.

  The source generation processing unit 105 reads a specification file stored in the specification file database 104 on the host, and generates a source file based on the read specification file. The method for generating the source file is the same as a general method. The generated source file is stored in the source file database 106. Correspondence information in which the generated source file is associated with the specification file used for generation is generated and stored in the correspondence information file database 107.

  FIG. 4 is a diagram showing an example of correspondence information stored in the correspondence information file database 107 shown in FIG.

  As shown in FIG. 4, the correspondence information 18 stored in the correspondence information file database 107 includes a specification page indicating the page number of the specification data, a line number in the specification indicating the line number in the specification data, and The generation start line number indicating the generation start line number of the source program generated on the basis of the source program and the generation end line number indicating the generation end line number of the source program are associated with each other.

  For example, the specification page “1”, the line number “1” in the specification, the generation start line number “1”, and the generation end line number “1” are associated with each other. This indicates that the first to first lines of the source program are generated based on the first line of the first page of the specification data. The same applies to other associations.

  The compile processing unit 108 reads a source file stored in the source file database 106, translates the read source file, and generates an object file. The method for generating this object file is the same as a general method. The generated object file is stored in the object file database 109. When the compile processing unit 108 optimizes the source file and compiles, the information on the line number of the optimized line is stored in the optimization information file database 110 as optimization information.

  FIG. 5 is a diagram showing an example of optimization information stored in the optimization information file database 110 shown in FIG.

  As shown in FIG. 5, the optimization information 19 stored in the optimization information file database 110 has an optimized line number indicating an optimized line number.

  The link processing unit 111 reads an object file stored in the object file database 109, and generates an executable file that can be executed on a computer based on the read object file. The method for generating the executable file is the same as a general method. The generated executable file is stored in the executable file database 112.

  The debug information creation processing unit 113 reads the correspondence information 18 stored in the correspondence information file database 107 and the optimization information 19 stored in the optimization information file database 110, and reads the corresponding correspondence information 18 and the optimization. Based on the information 19, a debug information file is created. The generated debug information file is stored in the debug information file database 114 on the host.

  FIG. 6 is a flowchart for explaining processing in the debug information creation processing unit 113 shown in FIG.

  First, the generation start line number and generation end line number associated with the specification page of the correspondence information 18 stored in the correspondence information file database 107 and the line number in the specification are read out line by line (step S1). .

  At this time, it is determined whether there is a line number in the specification (step S2). That is, since the correspondence information 18 is sequentially read line by line, it is possible to determine whether or not the processing for all the correspondence information 18 has been completed by this determination.

  If it is determined that there is no line number in the specification, the process ends.

  On the other hand, when it is determined that there is a line number in the specification, it is determined whether or not the generation start line number included in the read correspondence information 18 is equal to or less than the optimization line number included in the optimization information 19. (Step S3).

  When the generation start line number is equal to or less than the optimization line number included in the optimization information 19, the generation end line number included in the read correspondence information 18 is greater than or equal to the optimization line number included in the optimization information 19. It is determined whether or not there is (step S4).

  When the generation end line number is equal to or greater than the optimization line number included in the optimization information 19, the optimization information is set to “1 (optimized)” and is associated with the specification page and the line number in the specification. (Step S5).

  On the other hand, if the generation start line number is not less than or equal to the optimization line number included in the optimization information 19 in step S3, or the optimization line in which the generation end line number is included in the optimization information 19 in step S4. If the number is not greater than or equal to the number, the optimization information is set to “0 (no optimization)” and is associated with the specification page and the line number in the specification (step S6).

  In step S5 and step S6, the optimization information associated with the specification page, the specification line number, the generation start line number, and the generation end line number is stored in the debug information file database 114 on the host ( Added) (step S7). Let this association be a debug information file.

  FIG. 7 is a diagram showing an example of a debug information file stored in the debug information file database 114 on the host shown in FIG.

  As shown in FIG. 7, the debug information file 20 stored in the debug information file database 114 on the host has a specification page, a specification line number, a generation start line number, a generation end line number, an optimum Are associated with each other.

  For example, a specification page “1”, a line number “1” in the specification, a generation start line number “1”, a generation end line number “1”, and optimization information “0” are associated with each other. . This means that the first to first lines of the source program are generated based on the first line of the first page of the specification data, and the object file generated from them is not optimized. Show. The specification page “1”, the line number “10” in the specification, the generation start line number “8”, the generation end line number “8”, and the optimization information “1” are associated with each other. . This is because the 8th to 8th lines of the source program are generated based on the 10th line of the first page of the specification data, and the object file generated from them is optimized. Show. The same applies to other associations.

  Also, the debug information transfer processing unit 115 reads the debug information file 20 stored in the debug information file database 114 on the host and transmits it to the terminal 100 via the network 200.

  The debug file database 116 on the terminal stores the debug information file 20 transmitted from the debug information transfer processing unit 115.

  The debug information display processing unit 117 displays the specification file 21 stored in the specification file database 102 on the terminal and the debug information file 20 stored in the debug file database 116 on the terminal. This display is displayed on a display or the like provided in the terminal 100. At this time, the debug information file 20 is superimposed on the specification file 21 and displayed. Specifically, the line number of the source file corresponding to the specification file 21 is displayed, and a display such as color coding is given to the optimized line.

  FIG. 8 is a flowchart for explaining the processing in the debug information display processing unit 117 shown in FIG.

  First, specification information is read from the specification file 21 (step S11). Here, the specification information is the specification page, the line number in the specification and the text shown in FIG.

  Subsequently, the specification page with optimization and the line number in the specification are read from the debug information file 20 (step S12).

  Then, the specification file 21 is displayed with the line number of the source file corresponding to the specification file 21 added, and the portion with optimization read in step S12 is shaded ( Step S13).

  Then, a specification file in which a portion with optimization is shaded is displayed (step S14). This shading may be provided with a display (identification display) such as color coding that can be identified as described above.

  FIG. 9 is a diagram illustrating an example of the specification file displayed on the terminal 100 in the process of step S14.

  As shown in FIG. 9, the terminal 100 displays the specification file to which the line number of the source file is added, and displays the optimized lines (0008, 0021 and 0022) so that they can be identified on the specification data. Has been.

  In this way, an operator (user) creates a program that can be executed simply by inputting (creating) specification data, refers to the line number of the source file generated when debugging, and executes it. Even when the object file is optimized, its line number and its contents can be recognized. This has the effect of being able to debug efficiently.
