Comment 1:

debug/dwarf says
func New(abbrev, aranges, frame, info, line, pubnames, ranges, str []byte) (*Data, error)
    New returns a new Data object initialized from the given parameters.
    Clients should typically use [TODO(rsc): method to be named later]
    instead of calling New directly.
and the answer for the TODO is to use the DWARF method on the File type
in debug/elf, debug/macho, or debug/pe.
