<h4 class="subsection">6.58.11 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>Most of the functions are named after specific FR-V instructions.
|
||
|
|
Such functions are said to be “directly mapped” and are summarized
|
||
|
|
here in tabular form.
