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 14:18:55 +02:00			`// run-pass`

Translate constructor arguments for zero-sized tuple structs This was preventing any side-effects from the expressions from happening. Fixes #28114 2015-08-31 23:57:41 +12:00			`#![allow(unused_assignments)]`

Rename trans to codegen everywhere. 2018-05-08 16:10:16 +03:00			`// Make sure that the constructor args are codegened for zero-sized tuple structs`
