No; objdump doesn't understand Dwarf 2.  What you can do is compile
with -gdwarf-2 -save-temps -dA, which will emit Dwarf 2, keep the
assembly file, and annotate the Dwarf 2 with human-readable comments.
For example:

	.uleb128 0x1f	# (DIE (0x1174) DW_TAG_formal_parameter)
	.ascii "n\0"	# DW_AT_name
	.byte	0x1	# DW_AT_decl_file
	.byte	0x5	# DW_AT_decl_line
	.long	0xe1	# DW_AT_type
	.byte	0x1	# DW_AT_location
	.byte	0x55	# DW_OP_reg5

(This die shows register 'n' being allocated to register 5.  Whatever
that is. :) )
