Replacing the _mm_testz_si128 Function

This function is used to calculate the bit operation results of vectors a and b. For details about _mm_testz_si128, see Intrinsics Guide.

• Code on x86:

  all_zeros = _mm_testz_si128(zero_bytes, zero_bytes);

• Alternative for Kunpeng processors:

  #include <arm_neon.h>
  all_zeros = vgetq_lane_s32(vandq_s32(zero_bytes, zero_bytes), 0) == 0;
