<para>Copy the source SVE predicate register elements into the destination vector register as a packed bitmap with one bit per predicate element, where bit value 0b1 represents a TRUE predicate element, and bit value 0b0 represents a FALSE predicate element.</para>
|
|
<para>Because the number of bits in an SVE predicate element scales with the the vector element size, the behavior varies according to the specified element size.</para>
|
|
<list type="unordered">
|
|
<listitem>
|
|
<content>When the predicate element specifier is.B, every bit in the predicate register is copied to the least-significant VL/8 bits of the destination vector register. The immediate index, if specified, must be 0.</content>

</listitem>
|
|
<listitem>
|
|
<content>When the predicate element specifier is.H, every second bit in the predicate register is copied to the indexed block of VL/16 bits in the destination vector register, where the immediate index is in the range 0 to 1, inclusive.</content>
|
|
</listitem>
|
|
<listitem>
|
|
<content>When the predicate element specifier is.S, every fourth bit in the predicate register is copied to the indexed block of VL/32 bits in the destination vector register, where the immediate index is in the range 0 to 3, inclusive.</content>

</listitem>
|

<listitem>
|
|
<content>When the predicate element specifier is.D, every eighth bit in the predicate register is copied to the indexed block of VL/64 bits in the destination vector register, where the immediate index is in the range 0 to 7, inclusive.</content>
|
|
</listitem>
|
|
</list>
|
|
<para>The immediate index is optional, defaulting to 0 if omitted. When the index is zero, the instruction writes zeroes to the most significant VL-(VL/esize) bits of the destination vector register. When a non-zero index is specified, the packed bitmap is inserted into the destination vector register, and the unindexed blocks remain unchanged.</para>
