<h4 class="subsection">6.60.26 PowerPC Matrix-Multiply Assist Built-in Functions</h4>
<p>ISA 3.1 of the PowerPC added new Matrix-Multiply Assist (MMA) instructions.
GCC provides support for these instructions through the following built-in
functions which are enabled with the <code>-mmma</code> option.  The vec_t type
below is defined to be a normal vector unsigned char type.Â  The uint2, uint4
and uint8 parameters are 2-bit, 4-bit and 8-bit unsigned integer constants
respectively.Â  The compiler will verify that they are constants and that
their values are within range.Â 
</p>
<p>The built-in functions supported are:
