        that invokes _bfd_elf_find_nearest_line_discriminator with correct
        arguments.
	(_bfd_elf_find_nearest_line_discriminator): New.
	(_bfd_elf_find_line): Change to a wrapper
        that invokes _bfd_elf_find_line_discriminator with correct

	* bfd-in2.h: Regenerated.
	* libbfd.h: Likewise.
	* targets.c (BFD_JUMP_TABLE_SYMBOLS): Initialize
        _bfd_find_nearest_line_discriminator with
        _bfd_generic_find_nearest_line_discriminator.
        (bfd_target): Add _bfd_find_nearest_line_discriminator.

binutils/
	* addr2line.c (find_address_in_section): Invoke
        bfd_find_nearest_line_discriminator to get the discriminator.
	(find_offset_in_section): Likewise.
	(translate_addresses): Print discriminator if it is non-zero.
	* objdump.c (show_line): Invoke
        bfd_find_nearest_line_discriminator to get the discriminator,
        and keep track of prev_discriminator. Print discriminator
        if it is non-zero.
	(disassemble_data): Initialize prev_discriminator.
	(dump_reloc_set): Invoke bfd_find_nearest_line_discriminator
        to get the discriminator, and keep track of last_discriminator.
