+	* dwarf2.c (read_indirect_string, read_abbrevs,	decode_line_info,
+	_bfd_dwarf2_find_nearest_line): Use
+	bfd_simple_get_relocated_section_contents() instead of
+	bfd_get_section_contents().
+	* reloc.c (bfd_perform_relocation): Add sanity check.
+	* simple.c (simple_get_relocated_section_contents): If the section
+	does not have any relocs associated with it, just return the
+	unadjusted contents.
