tests: Add missing run-pass annotations 2019-07-26 16:54:25 -05:00
Normalize the type Self resolves to in an impl This is required at the very least in order to evaluate associated constants for arrays (see #58212). 2019-02-26 09:48:12 -06:00			`trait FromUnchecked {`
Remove mem::uninitalized from tests This purges uses of uninitialized where possible from test cases. Some are merely moved over to the equally bad pattern of MaybeUninit::uninit().assume_init() but with an annotation that this is "the best we can do". 2019-12-21 20:43:13 -06:00			`fn from_unchecked();`
