WebInclusion-based (i.e. Andersen-style) pointer analysis is an important point in the space of pointer analyses, offering a potential sweet-spot in the trade-off between precision and performance. However, current techniques for inclusion-based pointer analysis can have difficulties delivering on this potential. Web// In pointer analysis terms, this is a subset-based, flow-insensitive, // field-sensitive, and context-insensitive algorithm pointer algorithm. // // This algorithm is implemented as three stages: // 1. Object identification. // 2. Inclusion constraint identification. // 3. Offline constraint graph optimization // 4. Inclusion constraint solving.

Parallel Inclusion-based Points-to Analysis

WebPointer information is a prerequisite for most program analyses, and inclusion-based, i.e. Andersen-style, pointer analysis is widely used to compute such information. However, current inclusion-based analyses can have prohibitive costs in time and space, especially for programs with millions of lines of code. WebAug 31, 2016 · A points-to analysis in Java has to compute two sets of edges: (i) a set of unlabeled edges from variables to abstract heap objects, and (ii) a set of field-labeled edges between abstract objects. This is not the case for C/C++, where: 1. Objects can be allocated both on the stack and on the heap. 2. did mamie till have more childrenWebinsensitive inclusion-based pointer analysis efﬁciently [5]. This work showed that a BDD-based implementation could be competitive in performance with traditional im-plementations. Zhu also investigated using BDDs for pointer analysis [40,41].
