InstanceGraph

friend class InstanceGraph

friend

Iterates over the handshake::FuncOp's in the program to build an instance graph.

In doing so, we detect whether there are any cycles in this graph, as well as infer a top function for the design by performing a topological sort of the instance graph. The result of this sort is placed in sortedFuncs.
