That's only when we support __thread properly. For FreeBSD, they currently assume that we don't and have some sort of hack to fudge up some LDTs. So it is easy enough for them to just use dynamic LDT allocation as a work around until __thread is fully supported. > unfortunatly, for that to work we need to leave 10 or so words free for > now at (%gs) as they do their own __thread implementation > but we could do that for now without too much pain.. They only want to build one driver/openGL library for both -current and -stable. I told them to use getosreldate() or just handle an invalid return when trying to use i386_set_ldt(LDT_AUTO_ALLOC, ...). -- Dan
