Detailed Description

The data structure for the dependency graph.

Note that in this graph if there is an edge from A to B (A -> B), then it means that B depends on A, and when the state of A is updated, node B should also be updated

Member Data Documentation

◆ SyntheticRoot

AADepGraphNode llvm::AADepGraph::SyntheticRoot

There is no root node for the dependency graph.

But the SCCIterator requires a single entry point, so we maintain a fake("synthetic") root node that depends on every node.
