            Bug ID: 41937
           Summary: Duplicate JITDylib in the Search Order
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: OrcJIT
          Assignee: unassignedbugs at nondot.org

Currently, ORC allows to have a same name for multiple JITDylibs. Well, this
can be confusing for clients creating JITDylibs and populating code in it. For
a single ExecutionSession instance we should have JITDylib names. Possible
solution is have a check in ExecutionSession::createJITDylib method, and return
a Expected<JITDylib&>. 

Is multiple JITDylibs with same names serve a purpose? Is it a bug or feature? 

Thanks
