insertIntoLoop()

template<class BlockT , class LoopT >

void llvm::PopulateLoopsDFS< BlockT, LoopT >::insertIntoLoop ( BlockT *  Block )

protected

Add a single Block to its ancestor loops in PostOrder.

If the block is a subloop header, add the subloop to its parent in PostOrder, then reverse the Block and Subloop vectors of the now complete subloop to achieve RPO.
