armFish builds are made by Lyudmil Antonov for arm8 64-bit devices only, using direct cpu instructions via assembly language. This method is the most native but a little bit unhuman too. One would only bear this to obtain the fastest build.
I could not verify whether below build is made by Lyudmil too like previous ones, given that it was posted in another forum, not from Lyudmil's repository. By the way, it's hard to guess someone else would take the same difficult challenge to deal with the assembly language.
I still assume it's an LA build.
