--- Comment #8 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Except for native supported on a subset of the architectures, no values are the same, so this is highly target specific anyway. And yes, were it designed all now, we'd use the same options, but some of these choices are 33 years old, others 10, 20, 30 etc., so it is difficult to adjust it now without breaking stuff too much.
