Abstract

PURPOSE:To easily switch the module to be debugged by temporarily saving the content of a data section area where the module to be debugged is expanded to the file area corresponding to the module. CONSTITUTION:After the data section 002 of the current module to be debugged is preserved in a file area 008 and the module management table 007 of the module is preserved in a preserving area 009, the table 007 is retrieved. When the module information block coincident with a designated module name does not exist on the table 007, the module to be debugged is expanded and, when the block exists, the table 007 and the data section area 002 of the module to be debugged are returned to their original positions and the debugging process is terminated. Therefore, the module to be debugged can be easily switched.

As a result, the contents of the module management table 007 are transferred to the module management table storage area 009 of the current debug target module main.

Next, in a module management table search step S6 for the newly switched module sub, the module management table search means 106 searches the module management table storage area 009 for a module information block that matches the module name sub. Currently, the only table stored in the module management table storage area 009 is the table for module main, so it is determined that there is no table, and then the module to be debugged sub
In expansion step S3, the module expansion means 101 expands the data part of the module sub to be debugged into the data part area 002, and extracts the debug target module name sub, data pointer P and data size S of the data in the data part area 002. , and the file name TMPS[IB corresponding to the module to be debugged are stored in respective areas of the module management table 007.

Next, when the second process is performed, the current debug target module S
In step S1 of saving the data area of ub, the data area saving means 102 writes the data of the data area 002 to the file TMPS[IB, and in step S2 of saving the module management f-pull of the current debug target module sub, Module management table storage means 104
As a result, the contents of the module management table 007 are transferred to the module management table storage area 009 of the current debug target module sub.

Next, in a module management table search step S6 for the module main to be newly switched, the module management table search means 106 selects the module name main from the module management table storage area 009.
Search for module information blocks that match. Currently, the module mai is in the module management table storage area.
Since the table n is saved, it is determined that the table exists. Next, in step S4 of restoring the data area of the module to be debugged, the data area restoring means 103 reads the file TMPMAIN to the data area 002. In step S5 of restoring the module management table of the module to be debugged, the module management table restoring means 105 transfers the contents of the module management table from the module management table storage area 009 to the module management table 007. The results are shown in Figure 3 et al. In this way, debugging processing is performed.
