/* Test that inline functions declared "dllexport" appear in object
   files, even if they are not called.

   This behavior is required by the ARM C++ ABI:

     Exporting a function that can be inlined should force the
     creation and export of an out-of-line copy of it.

   and should presumably also apply.

   Visual Studio 2005 also honors that rule.  */
