Why wouldn't SIMD instructions work on C++? Just Curious

We run all of our tests using nim cpp for every commit so I can be confident C++ is not the issue here. The real question is why does it not work on your computer which is unfortunately much harder to answer from far away.

It appears clang on Mac requires pointers to be cast to something like const __m128i_u *. This is a made-up requirement, serves no purpose and is dumb. Fortunately no other compilers require it so I'm not eager to do anything here.
