Detailed Description

template<typename Impl>
class llvm::RuntimeDyldMachOCRTPBase< Impl >

RuntimeDyldMachOTarget - Templated base class for generic MachO linker algorithms and data structures.

Concrete, target specific sub-classes can be accessed via the impl() methods. (i.e. the RuntimeDyldMachO hierarchy uses the Curiously Recurring Template Idiom). Concrete subclasses for each target can be found in ./Targets.
