This section describes the available builtins and their usage in programs. With the <samp class="option">-msimd</samp> option, the compiler provides 128-bit vector types, which can be specified using the <code class="code">vector_size</code> attribute. The header file <samp class="file">arc-simd.h</samp> can be included to use the following predefined types: </p> +<div class="example"> <pre class="example-preformatted" data-language="cpp">typedef int __v4si __attribute__((vector_size(16))); +typedef short __v8hi __attribute__((vector_size(16)));</pre> +</div> <p>These types can be used to define 128-bit variables. The built-in functions listed in the following section can be used on these variables to generate the vector operations. </p> <p>For all builtins, <code class="code">__builtin_arc_<var class="var">someinsn</var></code>, the header file <samp class="file">arc-simd.h</samp> also provides equivalent macros called <code class="code">_<var class="var">someinsn</var></code> that can be used for programming ease and improved readability.
