--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
So we are essentially talking about a builtin like __builtin_cpu_{is,supports},
that instead of runtime check would query the target flags of the containing
function (if any) or the compilation unit default (if outside of function).
I think that is doable, but too late for GCC8.
