Add `// run-pass` annotations to all the tests under `ui/run-pass/`. (I may have accidentally added it to some auxilliary crates as well; my emacs-macro-based methodology was pretty crude.) 2018-08-30 12:18:55 +00:00			`// run-pass`

migrate codebase to `..=` inclusive range patterns These were stabilized in March 2018's #47813, and are the Preferred Way to Do It going forward (q.v. #51043). 2018-05-29 02:42:11 +00:00			`LOW_RANGE..=HIGH_RANGE => (),`
