Struct SccInfo

pub struct SccInfo {
    pub enter: usize,
    pub nodes: FxHashSet<usize>,
    pub exits: FxHashSet<SccExit>,
    pub backedges: Vec<(usize, usize)>,
    pub child_sccs: Vec<usize>,
}

Expand description

Per-header SCC metadata used by loop-aware analyses.

Fields§

§enter: usize

SCC entry / representative block.

§nodes: FxHashSet<usize>

SCC member set excluding enter.

§exits: FxHashSet<SccExit>

Edges leaving the SCC.

§backedges: Vec<(usize, usize)>

Edges inside the SCC region that go back to an earlier block or the representative.

§child_sccs: Vec<usize>

Representative nodes of nested child SCCs.

Implementations§

Source §

impl SccInfo

Source

pub fn new(enter: usize) -> Self

Create empty SCC metadata for enter.

Source

pub fn is_trivial(&self) -> bool

Returns true when this SCC contains only its representative and has no self-loop.

Source

pub fn enter(&self) -> usize

Compatibility accessor for older callers.
