On the other hand, the linker currently assumes that the order in
which relative relocations are emitted does not matter.  With a
different encoding scheme, future linkers might reorder the
relocations or data objects themselves, either to reduce relocation
encoding size, or to make relocations more efficient (perhaps to
support vectorization).  Unfortunately, the numbers which can be
derived from ET_DYN files will not reflect to what extent such
reordering is possible.
