/* The goal of this test is to provide anonymous DW_TAG_structure_type
   containing __pfn + __delta (read in by quirk_gcc_member_function_pointer)
   before DW_TAG_structure_type of "class C" to exploit the forward reference
   through "__pfn" and back from DW_TAG_member "fp" of "class C".  As the
   compiler may place the DIEs in arbitrary order they are rather prepared as
   a .S file.
