+ 2010-04-08 Nick Clifton <nickc@redhat.com>
+
+ Import these patches from the mainline:
+
+ 2010-04-05 Jakub Jelinek <jakub@redhat.com>
+
+ * elf-eh-frame.c (_bfd_elf_parse_eh_frame): Handle CIE version 4
+ provided that it has the expected address size and zero segment
+ length.
+ * dwarf2.c (struct line_head): Add maximum_ops_per_insn field.
+ (struct line_info): Add op_index field, change end_sequence type to
+ unsigned char.
+ (new_line_sorts_after): For the same address compare op_index.
+ (add_line_info): Add op_index argument, store it into the structure.
+ (decode_line_info): Complain about unknown versions of .debug_line.
+ Initialize maximum_ops_per_insn. Add op_index state register and
+ track it.
+
+ 2010-04-01 Jakub Jelinek <jakub@redhat.com>
+
+ * dwarf2.c (read_attribute_value): Handle CU version 4
+ for DW_FORM_ref_addr, handle DW_FORM_sec_offset, DW_FORM_exprloc
+ and DW_FORM_flag_present. For unknown form value return NULL.
+ (scan_unit_for_symbols): For DW_AT_location handle DW_FORM_exprloc
+ like DW_FORM_block.
+ (parse_comp_unit): Allow CU version 4.
