[LLVMdev] Find mallocs from a DSNode

[Scott Mikula]

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,
