Macro simdeez::simd_runtime_generate

macro_rules! simd_runtime_generate {
    ($vis:vis fn $fn_name:ident ($($arg:ident:$typ:ty),*) $(-> $rt:ty)? $body:block  ) => { ... };
}

Generates a generic version of your function (fn_name), and versions for:

• AVX2 (fn_name_avx2)
• SSE41 (fn_name_sse41)
• SSE2 (fn_name_sse2)
• Scalar fallback (fn_name_scalar) Finally, it also generates a function which will select at runtime the fastest version from above that the cpu supports. (fn_name_runtime_select)
