Description

Vector Bitwise NOT (register) takes a value from a register, inverts the value of each bit, and places the result in the destination register. The registers can be either doubleword or quadword. Depending on settings in the CPACR, NSACR, and HCPTR registers, and the Security state and PE mode in which the instruction is executed, an attempt to execute the instruction might be undefined, or trapped to Hyp mode. For more information see Enabling Advanced SIMD and floating-point support.

Operation

if ConditionPassed() then
    EncodingSpecificOperations();  CheckAdvSIMDEnabled();
    for r = 0 to regs-1
        D[d+r] = NOT(D[m+r]);
