Detailed Description

LazyObjectLinkingLayer is an adapter for ObjectLinkingLayer that builds lazy reexports for all function symbols in objects that are/ added to defer linking until the first call to a function defined in the object.

Linking is performed by emitting the object file via the base ObjectLinkingLayer.

No partitioning is performed: The first call to any function in the object will trigger linking of the whole object.

References to data symbols are not lazy and will trigger immediate linking (same os ObjectlinkingLayer).
