so then, if i want my code to "explicitly" use avx512, i have to do something like this?

``` void myNotOptimizedThing(my_data* d){ _SPECIAL_CPU_MANUFACTURER_0X3D512(d); } ```

edit: and include some header from the manufacturer most likely?

without using intrinsics? `-O3 -march=skylake-avx512 -mprefer-vector-width=512`
