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`
Add `#![allow(..)]` as necessary to get re-migrated run-pass tests compiling with clean stderr again. Most were added mechanically. 2018-09-25 21:51:35 +00:00			`#![allow(unreachable_code)]`
Parse try blocks with the try keyword instead of do catch placeholder 2018-07-22 03:59:44 +00:00			`// compile-flags: --edition 2018`

Rename `catch_expr` feature to `try_blocks` 2018-07-25 01:03:25 +00:00			`#![feature(try_blocks)]`
Mark block exits as reachable if the block can break. 2017-10-16 04:18:08 +00:00
