Inclusion-based pointer analysis

Webinclusion-based points-to analysis for strictly-typed object-oriented languages. Our implementation easily scales to millions of lines of Java code, and it supports language features such as inheritance, object fields, exceptional control flow, type casting, dynamic dispatch, and reflection. WebInclusion-based PTAs are typically flow-sensitive but context-insensitive. Unification-based PTAs are typically context-sensitive but flow-insensitive. 11 Unification-based PTA -- an …

The fine-grained and parallel complexity of andersen’s

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. WebPointer analysis is just a prerequi-site to our pointer recoder. 2.1 Related Work The general problem of pointer analysis can be divided into two parts, Points-To and Alias analysis. Points-to analysis attempts to statically determine the memory lo-cations a pointer can point to. On the other hand, alias analysis attempts to determine if two ...
