A revitalized interprocedural slicing in the presence of derived and user defined data types

Abstract

We propose an innovative approach for handling dynamic memory, arrays, pointers, structures and union by interprocedural dynamic slicing technique which combines the basic techniques from past and current trends of dynamic interprocedural slicing. At first an improved algorithm for interprocedural dynamic slicing in the presence of derived and user defined data type is given. Secondly the dynamic slices for different derived and user defined data types used in the respective programs are obtained. The proposed extended interprocedural dynamic slicing algorithm is more efficient then the existing algorithm as it gives a detailed idea about the slices that can be obtained for one dimensional pointers, two dimensional pointer, pointer and arrays, dynamic memory allocation, structures and union. The illustrations are given with the programs for the proof of correctness of the proposed algorithm.
