  architecture.  These extensions are read from the '.arcextmap' or
  '.gnu.linkonce.arcextmap.<type>.<N>' sections in the ELF file which
  is identified by the bfd parameter to the build_ARC_extmap function.

	 instructions
	 condition codes

  Once the table has been constructed, accessor functions may be used
  to retrieve information from it.

  The build_ARC_extmap constructor function build_ARC_extmap may be
