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`
Warn about useless assignments of variables/fields to themselves 2021-07-14 15:34:28 +02:00			`#![allow(dead_code)]`
fallout: run-pass tests that use box. (many could be ported to `Box::new` instead in the future.) 2015-01-08 02:25:56 +01:00
test: Make all the run-pass tests use `pub fn main` 2014-01-03 15:30:54 -08:00			`pub fn main() {`
Remove even more box syntax uses from src/test Prior work, notably 6550021124451628b1efc60c59284465b109e3aa from #88316 has removed box syntax from most of the testsuite. However, some tests were left out. This commit removes box_syntax uses from more locations in src/test. Some tests that are very box syntax specific are not being migrated. 2022-07-07 04:36:10 +02:00			`let mut x: Box<_> = Box::new(3);`
