 	PR ld/3191
-	* dwarf2.c (_bfd_dwarf2_find_nearest_line): Adjust debug_info
+	* dwarf2.c (find_abstract_instance_name): Pass a pointer to
+	attribute instead of offset.  For DW_FORM_ref_addr, get the
+	entry at the offset from the .debug_info section.
+	(scan_unit_for_symbols): Updated.
+	(_bfd_dwarf2_find_nearest_line): Adjust debug_info
 	section vma when needed.
