feature error span on attr. for fn_must_use, SIMD/align, macro reëxport There were several feature-gated attributes for which the feature-not-available error spans would point to the item annotated with the gated attribute, when it would make more sense for the span to point to the attribute itself: if the attribute is removed, the function/struct/&c. likely still makes sense and the program will compile. (Note that we decline to make the analogous change for the `main`, `start`, and `plugin_registrar` features, for in those cases it makes sense for the span to implicate the entire function, of which there is little hope of using without the gated attribute.) 2017-08-27 01:00:33 +00:00			`#[repr(simd)] //~ ERROR SIMD types are experimental`
