+ DW_FORM_ref_addr is an offset relative to .debug_info.
+ Normally when using the GNU linker this is accomplished by
+ emitting a symbolic reference to a label, because .debug_info
+ sections are linked at zero. When there are multiple section
+ groups containing .debug_info, as there might be in a
+ relocatable object file, it would be reasonable to assume that
+ a symbolic reference to a label in any .debug_info section
+ might be used. Since we lay out multiple .debug_info
+ sections at non-zero VMAs (see place_sections), and read
+ them contiguously into stash->info_ptr_memory, that means
+ the reference is relative to stash->info_ptr_memory. */
