Good news! These days you can produce MSVC compatible binaries with Clang or even use Clang as a compiler from the C++ IDE.

Whether or not you can do this in practice is another matter, but it can be done.

Yeah, if you look at my examples, they're rather straightforward arithmetic with 4 dimensional vectors. There's very little need for any integer arithmetic or more exotic combinations of operations. A little fused multiply-and-add here and there.

But I haven't seen a better method for this, most of the code is CPU-agnostic and will compile to x86 or ARM code using all the available instruction sets (depending on compiler arguments, e.g. -mavx2 or -march=native). I really haven't seen a SIMD math lib with so little duplication for different CPUs elsewhere.
