--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- If this is indeed something that older versions of binutils don't handle and latest binutils do, then we probably need to reduce the assembly into a small testcase (or corresponding C) and include that in configure as another test for whether we should do the target cloning. But first we need to know if the assembly gcc emits is valid. I know nothing about SEH.
