analyze()

template<class BlockT, class LoopT>

void llvm::LoopInfoBase< BlockT, LoopT >::analyze

(

const DominatorTreeBase< BlockT, false > &

DomTree

)

Create the loop forest using a stable algorithm.

Analyze LoopInfo discovers loops during a reverse preorder DominatorTree traversal interleaved with backward CFG traversals within each subloop (discoverAndMapSubloop).

The backward traversal skips inner subloops, so this part of the algorithm is linear in the number of CFG edges.

Then build a loop-contiguous reverse postorder for in-loops blocks. Lists are header-first with each subloop's blocks contiguous, ordered by first appearance in RPO; SubLoops keep program order, TopLevelLoops reverse program order.

destroy()

template<class BlockT, class LoopT>

void llvm::LoopInfoBase< BlockT, LoopT >::destroy ( LoopT * L )

inline

Destroy a loop that has been removed from the LoopInfo nest.

This runs the destructor of the loop object making it invalid to reference afterward. The memory is retained so that the pointer to the loop remains valid.

The caller is responsible for removing this loop from the loop nest and otherwise disconnecting it from the broader LoopInfo data structures. Callers that don't naturally handle this themselves should probably call ‘erase’ instead.
