[LLVMdev] Getting the DSNode from a Pool Descriptor?
Depending on the value of dsa_pass_to_use, either EquivBUDataStructures
or EQTDDataStructures is used. In the case that the top-down DSA is
used, information is pushed down to nodes in callees. However,
if bottom-up DSA is used, information has only been merged upwards and
the nodes are not necessarily equivalent.

The program I'm analyzing is not dereferencing NULL pointers. I'm
querying the EquivBUDataStructures pass; what instances would cause the
DSGraph not to have any information about the pointer (and I thought
Unknown DSNodes were created for when we couldn't figure out the pointer
value?).

[LLVMdev] DSA getNodeForValue() Returning NULL Sometimes
I'm iterating over all LoadInst and StoreInst-type Instructions in a
Function, and getNodeForValue() is sometimes returning NULL. Why is
this happening? Shouldn't every load from or store to memory correspond
to some DSNode?

Not if the pointer is null or the pointer

You can sometimes get NULL DSNodes if a previously-run transform pass

[LLVMdev] Getting the DSNode from a Pool Descriptor?
I figure (hopefully correctly) that I can iterate over all pool
descriptors in a program by iterating over all users of poolinit and
looking at the first argument. However, once I have a pool descriptor,
I need to get its corresponding DSNode in the function in which it is
complete (or in the global graph if it is a global). How do I do this?
Thanks,
