Struct rustc_mir_transform::jump_threading::OpportunitySet

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..

Implementations

impl OpportunitySet

fn new( body: &Body<'_>, opportunities: Vec<ThreadingOpportunity> ) -> OpportunitySet

fn apply(&mut self, body: &mut Body<'_>)

Apply the opportunities on the graph.

fn apply_once(&mut self, index: usize, body: &mut Body<'_>)

fn update_predecessor_count( &mut self, terminator: &Terminator<'_>, incr: Update )

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
