Detailed Description

A MaterializationUnit represents a set of symbol definitions that can be materialized as a group, or individually discarded (when overriding definitions are encountered).

MaterializationUnits are used when providing lazy definitions of symbols to JITDylibs. The JITDylib will call materialize when the address of a symbol is requested via the lookup method. The JITDylib will call discard if a stronger definition is added or already present.
