Struct OpportunitySet

Source 
struct OpportunitySet {
    opportunities: Vec<ThreadingOpportunity>,
    involving_tos: IndexVec<BasicBlock, Vec<(usize, usize)>>,
    predecessors: IndexVec<BasicBlock, usize>,
}

Fields§

§opportunities: Vec<ThreadingOpportunity>§involving_tos: IndexVec<BasicBlock, Vec<(usize, usize)>>

For each bb, give the TOs in which it appears. The pair corresponds to the index in opportunities and the index in ThreadingOpportunity::chain.

§predecessors: IndexVec<BasicBlock, usize>

Cache the number of predecessors for each block, as we clear the basic block cache..
