	Vector Subtract Long subtracts the elements of one doubleword vector from the corresponding elements of another doubleword vector, and places the results in a quadword vector. Before subtracting, it sign-extends or zero-extends the elements of both operands. Vector Subtract Wide subtracts the elements of a doubleword vector from the corresponding elements of a quadword vector, and places the results in another quadword vector. Before subtracting, it sign-extends or zero-extends the elements of the doubleword operand. Depending on settings in the CPACR, NSACR, and HCPTR registers, and the security state and mode in which the instruction is executed, an attempt to execute the instruction might be UNDEFINED, or trapped to Hyp mode. Summary of access controls for Advanced SIMD functionality on page B1-1232 summarizes these controls. ARM deprecates the conditional execution of any Advanced SIMD instruction encoding that is not also available as a VFP instruction encoding, see Conditional execution on page A8-288.
