 <p>The MIPS-3D Application-Specific Extension (ASE) includes additional
 paired-single instructions that are designed to improve the performance
 of 3D graphics operations.  Support for these instructions is controlled
 by the <samp>-mips3d</samp> command-line option.
 </p>
 <p>The functions listed below map directly to a particular MIPS-3D
 instruction.  Please refer to the architecture specification for
 more details on what each instruction does.

 </p></dd>
 </dl>

 <p>The following multi-instruction functions are also available.
 In each case, <var>cond</var> can be any of the 16 floating-point conditions:
 <code>f</code>, <code>un</code>, <code>eq</code>, <code>ueq</code>, <code>olt</code>, <code>ult</code>,
 <code>ole</code>, <code>ule</code>, <code>sf</code>, <code>ngle</code>, <code>seq</code>,
 <code>ngl</code>, <code>lt</code>, <code>nge</code>, <code>le</code> or <code>ngt</code>.

 <p>These functions compare <var>a</var> and <var>b</var> using <code>cabs.<var>cond</var>.s</code>
 or <code>cabs.<var>cond</var>.d</code> and return the result as a boolean value.
 For example:

 </p>
 <p>These functions compare <var>a</var> and <var>b</var> using <code>cabs.<var>cond</var>.ps</code>
 and return either the upper or lower half of the result.  For example:
 </p>
 <div class="smallexample">

 <dd><p>Conditional move based on absolute comparison (<code>cabs.<var>cond</var>.ps</code>,

 <p>The <code>movt</code> functions return the value <var>x</var> computed by:
 </p>
 <div class="smallexample">

 <p>The <code>movf</code> functions are similar but use <code>movf.ps</code> instead

 </p>
 <p>These functions compare <var>a</var> and <var>b</var> using <code>c.<var>cond</var>.ps</code>
 or <code>cabs.<var>cond</var>.ps</code>.  The <code>any</code> forms return true if either
 result is true and the <code>all</code> forms return true if both results are true.
 For example:
 </p>
 <div class="smallexample">
 <pre class="smallexample">v2sf a, b;

   one_is_true ();

 (<code>c.<var>cond</var>.ps</code>/<code>cabs.<var>cond</var>.ps</code>,
 <code>bc1any4t</code>/<code>bc1any4f</code>).
 </p>
 <p>These functions use <code>c.<var>cond</var>.ps</code> or <code>cabs.<var>cond</var>.ps</code>
 to compare <var>a</var> with <var>b</var> and to compare <var>c</var> with <var>d</var>.
 The <code>any</code> forms return true if any of the four results are true
 and the <code>all</code> forms return true if all four results are true.
 For example:
 </p>
 <div class="smallexample">
 <pre class="smallexample">v2sf a, b, c, d;
 if (__builtin_mips_any_c_eq_4s (a, b, c, d))

   all_are_true ();
 else
   some_are_false ();
