<h4 class="subsection">9.16.1 i860 Notes</h4>
<p>This is a fairly complete i860 assembler which is compatible with the
UNIX System V/860 Release 4 assembler. However, it does not currently
support SVR4 PIC (i.e., <code>@GOT, @GOTOFF, @PLT</code>).
</p>
<p>Like the SVR4/860 assembler, the output object format is ELF32. Currently,
this is the only supported object format. If there is sufficient interest,
other formats such as COFF may be implemented.
</p>
<p>Both the Intel and AT&amp;T/SVR4 syntaxes are supported, with the latter
being the default.  One difference is that AT&amp;T syntax requires the &rsquo;%&rsquo;
prefix on register names while Intel syntax does not.  Another difference
is in the specification of relocatable expressions.  The Intel syntax
is <code>ha%expression</code> whereas the SVR4 syntax is <code>[expression]@ha</code>
(and similarly for the &quot;l&quot; and &quot;h&quot; selectors).
