| <h4 class="subsection">6.52.5 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. |
