<h3 class="section">2.10 Relocations</h3>
<p>BFD maintains relocations in much the same way it maintains
symbols: they are left alone until required, then read in
en-masse and translated into an internal form.  A common
routine <code>bfd_perform_relocation</code> acts upon the
canonical form to do the fixup.
</p>
<p>Relocations are maintained on a per section basis,
while symbols are maintained on a per BFD basis.
</p>
<p>All that a back end has to do to fit the BFD interface is to create
a <code>struct reloc_cache_entry</code> for each relocation
in a particular section, and fill in the right bits of the structures.
