--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Instead of adding -march= please add instead say -mavx2 -mno-avx512f or
whatever ISA set you want to pick, and probably also -mprefer-vector-width=256
or what you want. Otherwise people can still override it with --target_board
etc., say through -mtune= in there, or through -mISA options.
