示例1: ScanDominatorsForDefs

// Given a block which has had predecessors removed but is still reachable, test
// whether the block's new dominator will be closer than its old one and whether
// it will expose potential optimization opportunities.
static bool
IsDominatorRefined(MBasicBlock* block)
{
    MBasicBlock* old = block->immediateDominator();
    MBasicBlock* now = ComputeNewDominator(block, old);

    // If this block is just a goto and it doesn't dominate its destination,
    // removing its predecessors won't refine the dominators of anything
    // interesting.
    MControlInstruction* control = block->lastIns();
    if (*block->begin() == control && block->phisEmpty() && control->isGoto() &&
        !block->dominates(control->toGoto()->target()))
    {
        return false;
    }

    // We've computed block's new dominator. Test whether there are any
    // newly-dominating definitions which look interesting.
    if (block == old)
        return block != now && ScanDominatorsForDefs(now);
    MOZ_ASSERT(block != now, "Non-self-dominating block became self-dominating");
    return ScanDominatorsForDefs(now, old);
}
