Detailed Description

PATypeHolder - Holder class for a potentially abstract type. This uses efficient union-find techniques to handle dynamic type resolution. Unless you need to do custom processing when types are resolved, you should always use PATypeHolders in preference to PATypeHandles.

Member Function Documentation

Type * llvm::PATypeHolder::get (   )  const [inline]
 

get - This implements the forwarding part of the union-find algorithm for abstract types. Before every access to the Type*, we check to see if the type we are pointing to is forwarding to a new type. If so, we drop our reference to the type.
