Bit clear and exclusive-OR
This instruction performs a bitwise AND of the 128-bit vector in a source SIMD&FP register and the complement of the vector in another source SIMD&FP register, then performs a bitwise exclusive-OR of the resulting vector and the vector in a third source SIMD&FP register, and writes the result to the destination SIMD&FP register.
