Detailed Description

Generic ORC ABI support.

This class can be substituted as the target architecture support class for ORC templates that require one (e.g. IndirectStubsManagers). It does not support lazy JITing however, and any attempt to use that functionality will result in execution of an llvm_unreachable.
