'How to compare two vectors using SIMD and get a strncmp like result?
I want to achieve something like strncmp result but not that complicated I tried to read https://code.woboq.org/userspace/glibc/sysdeps/x86_64/multiarch/strcmp-avx2.S.html source code but I failed to understand it
suppose we have to 256 bit vector how can I compare these two based on 8 bit comparison to achieve result like strncmp
I know there is a library but I want to understand the basics.
how it return -1,0,1 result with _mm256_cmpeq_epi8 and _mm256_min_epu8
