<h4 class="subsection">5.48.1 Alpha Built-in Functions</h4>
<p>These built-in functions are available for the Alpha family of
processors, depending on the command-line switches used.
<p>The following built-in functions are always available. They
all generate the machine instruction that is part of the name.
<pre class="smallexample"> long __builtin_alpha_implver (void)
long __builtin_alpha_rpcc (void)
long __builtin_alpha_amask (long)

long __builtin_alpha_extwl (long, long)
long __builtin_alpha_extll (long, long)
long __builtin_alpha_extql (long, long)
long __builtin_alpha_extwh (long, long)
long __builtin_alpha_extlh (long, long)

long __builtin_alpha_insbl (long, long)
long __builtin_alpha_inswl (long, long)
long __builtin_alpha_insll (long, long)
long __builtin_alpha_insql (long, long)
long __builtin_alpha_inswh (long, long)
long __builtin_alpha_inslh (long, long)
long __builtin_alpha_insqh (long, long)
long __builtin_alpha_mskbl (long, long)

long __builtin_alpha_umulh (long, long)
long __builtin_alpha_zap (long, long)
long __builtin_alpha_zapnot (long, long)
</pre>
<p>The following built-in functions are always with <samp><span class="option">-mmax</span></samp>
or <samp><span class="option">-mcpu=</span><var>cpu</var></samp> where <var>cpu</var> is <code>pca56</code> or
later. They all generate the machine instruction that is part
of the name.
<pre class="smallexample"> long __builtin_alpha_pklb (long)
long __builtin_alpha_pkwb (long)
long __builtin_alpha_unpkbl (long)
long __builtin_alpha_unpkbw (long)

<p>The following built-in functions are always with <samp><span class="option">-mcix</span></samp>
or <samp><span class="option">-mcpu=</span><var>cpu</var></samp> where <var>cpu</var> is <code>ev67</code> or
later. They all generate the machine instruction that is part
of the name.
<pre class="smallexample"> long __builtin_alpha_cttz (long)
long __builtin_alpha_ctlz (long)
long __builtin_alpha_ctpop (long)
</pre>
<p>The following builtins are available on systems that use the OSF/1
PALcode. Normally they invoke the <code>rduniq</code> and <code>wruniq</code>
PAL calls, but when invoked with <samp><span class="option">-mtls-kernel</span></samp>, they invoke
<code>rdval</code> and <code>wrval</code>.
