--- Comment #12 from Jakub Jelinek <jakub at gcc dot gnu.org> --- If it is due to a bug in i386-builtins.def, with my patch there are just 60 bits in isa_flags and thus a couple of further isa bits could be moved there if really needed. And as I said earlier, I think it is possible to move some others in the other direction.
