BFMUL (vectors, predicated) BFloat16 floating-point multiply vectors (predicated) Multiply active BFloat16 elements of the second source vector to corresponding elements of the first source vector and destructively place the results in the corresponding elements of the first source vector. Inactive elements in the destination vector register remain unmodified. This instruction follows SVE2 non-widening BFloat16 numerical behaviors. ID_AA64ZFR0_EL1.B16B16 indicates whether this instruction is implemented.
