Function rustc_middle::mir::traversal::reverse_postorder

pub fn reverse_postorder<'a, 'tcx>(
    body: &'a Body<'tcx>
) -> impl Iterator<Item = (BasicBlock, &'a BasicBlockData<'tcx>)> + ExactSizeIterator + DoubleEndedIterator

Creates an iterator over the Body’s basic blocks, that:

• returns basic blocks in a reverse postorder,
• makes use of the BasicBlocks CFG cache’s reverse postorder.
