the avx instruction uses a non-standard interface.

When I compiled the code, I found that the following interfaces are not standard AVX interfaces. Can you provide the corresponding implementations?
_mm256_loadu_epi16
_mm_storeu_epi8
_mm256_storeu_epi16

Thanks for your notification!
These 3 instructions are available for CPUID Flags: AVX512BW + AVX512VL according to the Intel® Intrinsics Guide. Now, I have changed them to instructions providing identical results.

Thank you, the above problem has been solved. However, a new problem has arisen.
error: inlining failed in call to ‘always_inline’ ‘__m512i _mm512_popcnt_epi64(__m512i)’: target specific option mismatch
_mm512_popcnt_epi64 (__m512i __A)

it needs to add the -mavx512vpopcntdq option to CMakeLists.txt.

SET(CMAKE_CXX_FLAGS "-mavx512vpopcntdq -Wall -Ofast -Wextra -lrt -march=native -fpic -fopenmp -ftree-vectorize -fexceptions")

Thank you for pointing out the problem.
However, it is not about adding the option in CMakeLists.txt. The key issue the SIMD checking statements are inaccurate in the previous code. Now, I have updated the code to check if certain instructions are fully supported. You may try the new version.
