search for: unknownnode

Is there some efficient way to find the malloc instructions which point to the memory represented by a DSNode? Right now the only way I see is by iterating through the value map in the DSGraph object and finding every value that points to my DSNode. A possibly related question: is there a way to tell that the node has been merged, and if so, what types of nodes went into the merge? Thanks,

There are four flags that indicate the composition of the node: DSNode::AllocaNode, HeapNode, GlobalNode, UnknownNode. When two nodes are merged, their Flags are bitwise or'd together... -Chris -- http://llvm.cs.uiuc.edu/ http://www.nondot.org/~sabre/Projects/

I realized that, but what if two nodes of the same type are merged? Their flags will not indicate that a merge has occurred. I'm concerned about the case where two malloc nodes are merged, because then if free...
