Global Data Flow: Optimize `FlowGraph` Creation #21

Open JLLeitschuh opened 1 year ago

JLLeitschuh commented 1 year ago

Currently, we are redundantly creating multiple FlowGraph for paths that we've already previously computed. We could optimize this by having a cache of DataFlowNode to FlowGraph, such that when we attempt to create a FlowGraph for an existing DataFlowNode, we return the existing FlowGraph.

This could likely further be optimized if, while performing the data flow computation, we received a cached FlowGraph could stop the computation preemptively.
