Struct PostDominators

Source 
pub struct PostDominators<Node: Idx> { /* private fields */ }
Expand description

Represents the post-dominators of a graph’s nodes with respect to a particular exit.

Implementations§

Source§

impl<Node: Idx> PostDominators<Node>

Source

pub fn build<G: ControlFlowGraph<Node = Node>>(graph: &G, exit: Node) -> Self

Constructs the post-dominators by computing the dominators on a reversed graph.

Source

pub fn immediate_post_dominator(&self, node: Node) -> Option<Node>

Gets the node that immediately post-dominators node, if one exists.

Source

pub fn post_dominators( &self, node: Node, ) -> Option<impl Iterator<Item = Node> + '_>

Gets all nodes that post-dominate node, if they exist.
