[LLVMdev] Getting the DSNode from a Pool Descriptor?

[Harmen van der Spek]

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.
