Detailed Description

template<class T, class Ctx>
class llvm::ContextualFoldingSet< T, Ctx >

ContextualFoldingSet - This template class is a further refinement of FoldingSet which provides a context argument when calling Profile on its nodes.

Currently, that argument is fixed at initialization time.

T must be a subclass of FoldingSetNode and implement a Profile function with signature void Profile(FoldingSetNodeID &, Ctx);
