  77. <h4 class="subsection">6.60.26 PowerPC Matrix-Multiply Assist Built-in Functions</h4>

  78. <p>ISA 3.1 of the PowerPC added new Matrix-Multiply Assist (MMA) instructions.

  79. GCC provides support for these instructions through the following built-in

  80. functions which are enabled with the <code>-mmma</code> option.  The vec_t type

  81. below is defined to be a normal vector unsigned char type.  The uint2, uint4

  82. and uint8 parameters are 2-bit, 4-bit and 8-bit unsigned integer constants

  83. respectively.  The compiler will verify that they are constants and that

  84. their values are within range. 

  85. </p>

  86. <p>The built-in functions supported are:
