control value.</p>
<p>The <code>a:</code> and <code>b:</code> prefixes on the index selection values are literal tokens
that you type. It helps keep clear what value comes from where. The first
two output lanes come from <code>$a</code>, the second two output lanes come from <code>$b</code>.</p>
<p>You can pass the same value as both arguments, but if you want to swizzle
within only a single register and you have <code>avx</code> available consider using
[<code>shuffle_ai_f32_all_m128</code>] instead. Youll get much better performance.</p>
