--- Comment #6 from Jonathan Wakely <redi at gcc dot gnu.org> --- Yes, I think it's an extension, added by r14-1500-g4d935f52b0d5c0 The question then is whether the attribute is supposed to be a non-binding request or not. If it's a non-binding request then the test should be adjusted/unsupported for this target. If the latter, then that use of the attribute should be ill-formed for this target and give an error.
