Struct TraversalContext

Source 
struct TraversalContext {
    loop_header: Option<BasicCoverageBlock>,
    worklist: VecDeque<BasicCoverageBlock>,
}
Expand description

Maintains separate worklists for each loop in the BasicCoverageBlock CFG, plus one for the CoverageGraph outside all loops. This supports traversing the BCB CFG in a way that ensures a loop is completely traversed before processing Blocks after the end of the loop.

Fields§

§loop_header: Option<BasicCoverageBlock>

BCB with one or more incoming loop backedges, indicating which loop this context is for.

If None, this is the non-loop context for the function as a whole.

§worklist: VecDeque<BasicCoverageBlock>

Worklist of BCBs to be processed in this context.
