I have a similar project in C++ supporting SSE2,AVX2, and AVX512 here: https://github.com/dnbaker/vec https://github.com/dnbaker/vec. I've used it for numerical code and sketch data structures, for example. (See https://github.com/dnbaker/frp https://github.com/dnbaker/frp or https://github.com/dnbaker/sketch https://github.com/dnbaker/sketch, respectively). Most of the work I do, the compiler just isn't able to vectorize, so I just write intrinsics. I similarly wrapped FFTW and the Sleef trigonometric function library so that I can generate optimal code for a variety of types and architectures.
