<h4 class="subsection">6.59.12 FR-V Built-in Functions</h4>
<p>GCC provides many FR-V-specific built-in functions. In general,
these functions are intended to be compatible with those described
by <cite>FR-V Family, Softune C/C++ Compiler Manual (V6), Fujitsu
Semiconductor</cite>. The two exceptions are <code>__MDUNPACKH</code> and
<code>__MBTOHE</code>, the GCC forms of which pass 128-bit values by
pointer rather than by value.
</p>
<p>Most of the functions are named after specific FR-V instructions.
Such functions are said to be &ldquo;directly mapped&rdquo; and are summarized
here in tabular form.
