Hi Jakub,

2010-09-09 Jakub Jelinek<jakub@redhat.com>

	* dwarf.h (debug_info): Add offset_info and dwarf_version fields.
	* dwarf.c (decode_location_expression): Add offset_size and
	dwarf_version arguments.  Prefix DIE offset with 0x for
	DW_OP_call{2,4,_ref}.  Fix up DW_OP_call_ref operand size,
	complain if in frame info section.  Handle
	DW_OP_GNU_implicit_pointer.
	(read_and_display_attr_value, display_debug_loc,
	display_debug_frames): Adjust decode_location_expression callers.
	(process_debug_info): Save offset_size and dwarf_version values
	into debug_information array.

* dwarf2.h (DW_OP_GNU_implicit_pointer): New.

Approved - please apply - but ...

+ DW_OP_GNU_implicit_pointer = 0xf2,

Given that this is a GNU extension to the DWARF specification there ought to be comment providing a link to wherever it is documented.

Cheers
  Nick
