Detailed Description

template<typename ValueTy>
class llvm::TrackingVH< ValueTy >

TrackingVH - This is a value handle that tracks a Value (or Value subclass), even across RAUW operations.

TrackingVH is designed for situations where a client needs to hold a handle to a Value (or subclass) across some operations which may move that value, but should never destroy it or replace it with some unacceptable type.

It is an error to do anything with a TrackingVH whose value has been destroyed, except to destruct it.

It is an error to attempt to replace a value with one of a type which is incompatible with any of its outstanding TrackingVHs.
