<para>Vector Compare Greater Than or Equal takes each element in a vector, and compares it with the corresponding element of a second vector. If the first is greater than or equal to the second, the corresponding element in the destination vector is set to all ones. Otherwise, it is set to all zeros.</para>
|
|
<para>The operand vector elements are the same type, and are signed integers, unsigned integers, or floating-point numbers. The result vector elements are fields the same size as the operand vector elements.</para>
|
|
<para>Depending on settings in the <xref linkend="AArch32.cpacr">CPACR</xref>, <xref linkend="AArch32.nsacr">NSACR</xref>, and <xref linkend="AArch32.hcptr">HCPTR</xref> registers, and the Security state and PE mode in which the instruction is executed, an attempt to execute the instruction might be <arm-defined-word>undefined</arm-defined-word>, or trapped to Hyp mode. For more information see <xref linkend="CIHIDDFF">Enabling Advanced SIMD and floating-point support</xref>.</para>
