I think also code using x86_64 vectorization (AVX, SSE) is going to be non-trivial to port. Same applies to JITs, which I guess are a lot less mature on ARM due

I think also code using x86_64 vectorization (AVX, SSE) is going to be non-trivial to port. Same applies to JITs, which I guess are a lot less mature on ARM due to lack of users at the minute.
