I'm not really certain why you wish to add a VarDecl* "pointedBy" field into AnonTypedRegion? I didn't get around to commenting this class, but AnonTypedRegion is meant to represent a typed chunk of memory; it doesn't have to be pointed by a VarDecl. It also seems to me that you are using AnonTypedRegion exactly the way BasicStore uses VarRegion. Isn't it the same thing? The "Anon" means anonymous; it means there is no name associated with this region.<font color="#888888"></font></div>
</blockquote><div><br>I use VarDecl* to differentiate AnonTypedRegions. For example, for <br><br>void foo(char* a, char* b) {...}, <br></div></div><br>'a' and 'b' both points to an AnonTypedRegion with type 'char', I just use the VarDecl's of 'a' and 'b' to differentiate these two regions. This is definitely not optimal design, because there might be AnonTypedRegion that are not pointed to by any variable. So it should be discussed. But one thing is sure: we need something to be associated with AnonTypedRegion besides its type and superregion.<br>
