--- Comment #3 from Richard Guenther <rguenth at gcc dot gnu.org> 2011-11-06 12:46:43 UTC --- Well, I guess the testcase is simply invalid for MachO, or the way MachO does this UNSPEC stuff is broken (not properly checked during legitimization) or not properly restoring the UNSPEC during reload (it's its duty, not IRAs).
