14.133 VSUB

Vector Subtract.

VSUB{cond}.datatype {Qd}, Qn, Qm

VSUB{cond}.datatype {Dd}, Dn, Dm

where:

cond: is an optional condition code.
datatype: must be one of I8, I16, I32, I64, or F32.
Qd, Qn, Qm: are the destination vector, the first operand vector, and the second operand vector, for a quadword operation.

VSUB subtracts the elements of one vector from the corresponding elements of another vector, and places the results in the destination vector.
