<h5>Syntax:</h5>

<h5>Overview:</h5>
|
||||
|
||||
<p>The '<tt>vsetint</tt>' instruction takes two integer vectors and
|
||||
returns a vector of boolean values representing, at each position, the
|
||||
result of the comparison between the values at that position in the
|
||||
two operands.</p>
|
||||
|
||||
<h5>Arguments:</h5>
|
||||
|
||||
<p>The arguments to a '<tt>vsetint</tt>' instruction are a comparison
|
||||
operation and two value arguments. The value arguments must be of <a
|
||||
href="#t_integral">integral</a> <a href="#t_packed">packed</a> type,
|
||||
and they must have identical types. The operation argument must be
|
||||
one of <tt>eq</tt>, <tt>ne</tt>, <tt>slt</tt>, <tt>sgt</tt>,
|
||||
<tt>sle</tt>, <tt>sge</tt>, <tt>ult</tt>, <tt>ugt</tt>, <tt>ule</tt>,
|
||||
<tt>uge</tt>, <tt>true</tt>, and <tt>false</tt>. The result is a
|
||||
packed <tt>bool</tt> value with the same length as each operand.</p>
|
||||
|
||||
<h5>Semantics:</h5>
|
||||
|
||||
<p>The following table shows the semantics of '<tt>vsetint</tt>'. For
|
||||
each position of the result, the comparison is done on the
|
||||
corresponding positions of the two value arguments. Note that the
|
||||
signedness of the comparison depends on the comparison opcode and
|
||||
<i>not</i> on the signedness of the value operands. E.g., <tt>vsetint
|
||||
slt <4 x unsigned> %x, %y</tt> does an elementwise <i>signed</i>
|
||||
comparison of <tt>%x</tt> and <tt>%y</tt>.</p>

<h5>Overview:</h5>
|
||||
|
||||
<p>The '<tt>vsetfp</tt>' instruction takes two floating point vector
|
||||
arguments and returns a vector of boolean values representing, at each
|
||||
position, the result of the comparison between the values at that
|
||||
position in the two operands.</p>
|
||||
|
||||
<h5>Arguments:</h5>
|
||||
|
||||
<p>The arguments to a '<tt>vsetfp</tt>' instruction are a comparison
|
||||
operation and two value arguments. The value arguments must be of <a
|
||||
href="t_floating">floating point</a> <a href="#t_packed">packed</a>
|
||||
type, and they must have identical types. The operation argument must
|
||||
be one of <tt>eq</tt>, <tt>ne</tt>, <tt>lt</tt>, <tt>gt</tt>,
|
||||
<tt>le</tt>, <tt>ge</tt>, <tt>oeq</tt>, <tt>one</tt>, <tt>olt</tt>,
|
||||
<tt>ogt</tt>, <tt>ole</tt>, <tt>oge</tt>, <tt>ueq</tt>, <tt>une</tt>,

|
||||
<tt>u</tt>, <tt>true</tt>, and <tt>false</tt>. The result is a packed
|
||||
<tt>bool</tt> value with the same length as each operand.</p>
|
||||
|
||||
<h5>Semantics:</h5>
|
||||
|
||||
<p>The following table shows the semantics of '<tt>vsetfp</tt>' for
|
||||
floating point types. If either operand is a floating point Not a
|
||||
Number (NaN) value, the operation is unordered, and the value in the
|
||||
first column below is produced at that position. Otherwise, the
|
||||
operation is ordered, and the value in the second column is
|
||||
produced.</p>

<h5>Syntax:</h5>

|

<pre>

<result> = vselect <n x bool> <cond>, <n x <ty>> <val1>, <n x <ty>> <val2> <i>; yields <n x <ty>></i>

</pre>
|

|

<h5>Overview:</h5>
|
||||
|
||||
<p>
|
||||
The '<tt>vselect</tt>' instruction chooses one value at each position
|
||||
of a vector based on a condition.
|
||||
</p>
|
||||
|
||||
|
||||
<h5>Arguments:</h5>
|
||||
|
||||
<p>
|
||||
The '<tt>vselect</tt>' instruction requires a <a
|
||||
href="#t_packed">packed</a> <tt>bool</tt> value indicating the
|
||||
condition at each vector position, and two values of the same packed
|
||||
type. All three operands must have the same length. The type of the
|
||||
result is the same as the type of the two value operands.</p>
|
||||
|
||||
<h5>Semantics:</h5>
|
||||
|
||||
<p>
|
||||
At each position where the <tt>bool</tt> vector is true, that position
|
||||
of the result gets its value from the first value argument; otherwise,
|
||||
it gets its value from the second value argument.
|
||||
</p>

||||

||||
<h5>Example:</h5>
|
||||
|
||||
<pre>
|
||||
%X = vselect bool <2 x bool> <bool true, bool false>, <2 x ubyte> <ubyte 17, ubyte 17>,
|
||||
<2 x ubyte> <ubyte 42, ubyte 42> <i>; yields <2 x ubyte>:17, 42</i>
