<h4 class="subsection">6.58.14 MIPS Loongson Built-in Functions</h4>
|
|
|
|
<p>GCC provides intrinsics to access the SIMD instructions provided by the
|
|
ST Microelectronics Loongson-2E and -2F processors. These intrinsics,
|
|
available after inclusion of the <code>loongson.h</code> header file,
|
|
operate on the following 64-bit vector types:
|
|
|
|
<ul>
|
|
<li><code>uint8x8_t</code>, a vector of eight unsigned 8-bit integers;
|
|
<li><code>uint16x4_t</code>, a vector of four unsigned 16-bit integers;
|
|
<li><code>uint32x2_t</code>, a vector of two unsigned 32-bit integers;
|
|
<li><code>int8x8_t</code>, a vector of eight signed 8-bit integers;
|
|
<li><code>int16x4_t</code>, a vector of four signed 16-bit integers;
|
|
<li><code>int32x2_t</code>, a vector of two signed 32-bit integers.
|
|
</ul>
|
|
|
|
<p>The intrinsics provided are listed below; each is named after the
|
|
machine instruction to which it corresponds, with suffixes added as
|
|
appropriate to distinguish intrinsics that expand to the same machine
|
|
instruction yet have different argument types. Refer to the architecture
|
|
documentation for a description of the functionality of each
|
|
instruction.
