Detailed Description

template<typename T>
class llvm::polymorphic_ptr< T >

An owning, copyable polymorphic smart pointer.

This pointer exists to provide copyable owned smart pointer. Rather than shared ownership semantics, it has unique ownership semantics and deep copy semantics. It is copyable by requiring that the underlying type exposes a method which can produce a (heap allocated) clone.

Note that in almost all scenarios use of this could be avoided if we could build move-only containers of a std::unique_ptr, but until then this provides an effective way to place polymorphic objects in a container.
