Interprocedural pointer alias analysis
WebThe new alias information after p, denoted by hr′ , pit , is updated in the back-tracking cell: h r ′ ial h et q ee . . .ik h h r, p it h r, q ie . . .ibkt-te (27) r q ee h r ′ , p it Eventually, if the successful execution of q (marked by ee at the top of h−ik ) produces an alias relation r′′ , then the final alias information becomes r′ ∪ r′′ , where r′ is the aliasing ... WebJun 1, 1994 · Existing methods for alias analysis of recursive pointer data structures are based on two approximation techniques: k-limiting, and store-based (or equivalently …

Webdiscusses design and implementation of an interprocedural analysis of aggregates which is capable of identifying aggregates which are used in a simple way so that they do not have any aliases. Moreover, the ... the analysis was able to detect that about 20% of aggregates and pointers and references to them were used simply enough and thus can ...

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 ...
