            Bug ID: 17689
           Summary: [-cxx-abi microsoft] static const integers initialized
                    in a class should be linkonce_odr
           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: llvmbugs at cs.uiuc.edu
    Classification: Unclassified

MSVC emits static const integral class members in COMDATs, and the linker will
complain if clang requires users to provide a strong definition in a .cpp file.
 Therefore we have to implement this extension in order to be ABI compatible
with MSVC.
