A lot of optimizations in DFG assume a DAG, but the more things are representable, the more likely it is that a small cyclic sub-graph is present in an otherwise very large graph that is mostly acyclic. In order to avoid loosing optimization opportunities, we explicitly extract the cyclic sub-graphs (which are the strongly connected components + anything feeing them, up to variable boundaries) and treat them separately. This enables optimization of the remaining input. |
