Detailed Description

Base class for a JIT linker.

A JITLinkerBase instance links one object file into an ongoing JIT session. Symbol resolution and finalization operations are pluggable, and called using continuation passing (passing a continuation for the remaining linker work) to allow them to be performed asynchronously.
