Vector Compare takes the value of each element in a vector, and compares it with the value of the corresponding element of a second vector, or zero. If the condition is true, the corresponding element in the destination vector is set to all ones. Otherwise, it is set to all zeros.
Note
On disassembly, these pseudo-instructions are disassembled
to the corresponding VCGE and VCGT instructions,
with the operands reversed.

where:
opmust be one of:
LELess than or Equal
LTLess Than.
condis an optional condition code.
datatypemust be one of
S8,S16,S32,U8,U16,U32, orF32.QdorDdis the NEON register for the result.
The result datatype is:

QnorDnis the NEON register holding the first operand.
QmorDmis the NEON register holding the second operand.
