            Bug ID: 27079
           Summary: Add an MSVC Language Runtime ABI
           Product: lldb
           Version: unspecified
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: lldb-dev at lists.llvm.org

    Classification: Unclassified

Right now the only C++ language runtime assumes Itanium ABI.  This is probably
the reason for a number of test failures, especially those involving virtual
bases, functions, and dynamic types.  We will need to add one for MSVC ABI. 
Less importantly, it is possible for MSVC and Itanium ABI modules to be loaded
into the same process.  The system doesn't seem well designed to handle this,
so it will probably be some effort to get that working.
