In general, 62these functions are intended to be compatible with those described 63by <cite>FR-V Family, Softune C/C++ Compiler Manual (V6), Fujitsu 64Semiconductor</cite>. The two exceptions are <code>__MDUNPACKH</code> and 65<code>__MBTOHE</code>, the gcc forms of which pass 128-bit values by 66pointer rather than by value. 67 68 <p>Most of the functions are named after specific FR-V instructions. 69Such functions are said to be “directly mapped” and are summarized 70here in tabular form. 71 72<ul class="menu"> 73<li><a accesskey="1" href="Argument-Types.html#Argument-Types">Argument Types</a> 74<li><a accesskey="2" href="Directly_002dmapped-Integer-Functions.html#Directly_002dmapped-Integer-Functions">Directly-mapped Integer Functions</a> 75<li><a accesskey="3" href="Directly_002dmapped-Media-Functions.html#Directly_002dmapped-Media-Functions">Directly-mapped Media Functions</a> 76<li><a accesskey="4" href="Raw-read_002fwrite-Functions.html#Raw-read_002fwrite-Functions">Raw read/write Functions</a> 77<li><a accesskey="5" href="Other-Built_002din-Functions.html#Other-Built_002din-Functions">Other Built-in Functions</a> 78</ul> 79 80 </body></html> 81 82
