            Bug ID: 28281
           Summary: [codeview] Clang needs to emit DW_TAG_inheritance
                    nodes for all indirect virtual bases
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: LLVM Codegen
          Assignee: unassignedclangbugs at nondot.org
          Reporter: rnk at google.com
                CC: llvm-bugs at lists.llvm.org
            Blocks: 28154
    Classification: Unclassified

We need them because MSVC lists all morally virtual bases of a class in its
field list record. We can't walk the inheritance hierarchy of our direct bases
to find them because our direct bases might be forward declarations.
