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");
