示例1: breakCriticalEdges
void breakCriticalEdges(Procedure& proc)
{
BlockInsertionSet insertionSet(proc);
for (BasicBlock* block : proc) {
// Non-void terminals that are the moral equivalent of jumps trigger critical edge breaking
// because of fixSSA's demoteValues.
if (block->numSuccessors() <= 1
&& block->last()->type() == Void)
continue;
for (BasicBlock*& successor : block->successorBlocks()) {
if (successor->numPredecessors() <= 1)
continue;
BasicBlock* pad =
insertionSet.insertBefore(successor, successor->frequency());
pad->appendNew<Value>(proc, Jump, successor->at(0)->origin());
pad->setSuccessors(FrequentedBlock(successor));
pad->addPredecessor(block);
successor->replacePredecessor(block, pad);
successor = pad;
}
}
if (insertionSet.execute())
proc.invalidateCFG();
}
