Detailed Description

template<class T>
class llvm::FoldingSet< T >

FoldingSet - This template class is used to instantiate a specialized implementation of the folding set to the node class T.

T must be a subclass of FoldingSetNode and implement a Profile function.

Note that this set type is movable and move-assignable. However, its moved-from state is not a valid state for anything other than move-assigning and destroying. This is primarily to enable movable APIs that incorporate these objects.
