--- Comment #8 from Valeriy E. Ushakov <uwe at netbsd dot org> --- I don't understand. The title mentions sh3, which is not obsolete. It's been 11 (eleven!) years. As far as I know this patch (adjusted to catch up with the changes, but essentially the same) is still necessary for gcc 6.4 that is the compiler in NetBSD-current.
