<h3 class="section">4.2 <code>ld</code> and the Intel 960 Family</h3>

<a name="index-i960-support"></a>

<p>You can use the &lsquo;<samp>-A<var>architecture</var></samp>&rsquo; command line option to
specify one of the two-letter names identifying members of the 960
family; the option specifies the desired output target, and warns of any
incompatible instructions in the input files.  It also modifies the
linker&rsquo;s search strategy for archive libraries, to support the use of
libraries specific to each particular architecture, by including in the
search loop names suffixed with the string identifying the architecture.
</p>
<p>For example, if your <code>ld</code> command line included &lsquo;<samp><span class="nolinebreak">-ACA</span></samp>&rsquo;<!-- /@w --> as
well as &lsquo;<samp><span class="nolinebreak">-ltry</span></samp>&rsquo;<!-- /@w -->, the linker would look (in its built-in search
paths, and in any paths you specify with &lsquo;<samp>-L</samp>&rsquo;) for a library with
the names
</p>
<div class="smallexample">
<pre class="smallexample">try
libtry.a
tryca
libtryca.a
</pre></div>

<p>The first two possibilities would be considered in any event; the last
two are due to the use of &lsquo;<samp><span class="nolinebreak">-ACA</span></samp>&rsquo;<!-- /@w -->.
</p>
<p>You can meaningfully use &lsquo;<samp>-A</samp>&rsquo; more than once on a command line, since
the 960 architecture family allows combination of target architectures; each
use will add another pair of name variants to search for when &lsquo;<samp><span class="nolinebreak">-l</span></samp>&rsquo;<!-- /@w -->
specifies a library.
</p>
<a name="index-_002d_002drelax-on-i960"></a>
<a name="index-relaxing-on-i960"></a>
<p><code>ld</code> supports the &lsquo;<samp>--relax</samp>&rsquo; option for the i960 family.  If
you specify &lsquo;<samp>--relax</samp>&rsquo;, <code>ld</code> finds all <code>balx</code> and
<code>calx</code> instructions whose targets are within 24 bits, and turns
them into 24-bit program-counter relative <code>bal</code> and <code>cal</code>
instructions, respectively.  <code>ld</code> also turns <code>cal</code>
instructions into <code>bal</code> instructions when it determines that the
target subroutine is a leaf routine (that is, the target subroutine does
not itself call any subroutines).
