/* The goal of this test is to provide anonymous DW_TAG_structure_type

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.
