tests: Add missing run-pass annotations 2019-07-26 21:54:25 +00:00			`//@ run-pass`
rustdoc: Replace no-pretty-expanded with pretty-expanded Now that features must be declared expanded source often does not compile. This adds 'pretty-expanded' to a bunch of test cases that still work. 2015-03-22 20:13:15 +00:00			`//@ pretty-expanded FIXME #23616`

librustc: Remove `~EXPR`, `~TYPE`, and `~PAT` from the language, except for `~str`/`~[]`. Note that `~self` still remains, since I forgot to add support for `Box<self>` before the snapshot. How to update your code: * Instead of `~EXPR`, you should write `box EXPR`. * Instead of `~TYPE`, you should write `Box<Type>`. * Instead of `~PATTERN`, you should write `box PATTERN`.

Remove box syntax from most places in src/test outside of the issues dir 2021-08-25 00:39:40 +00:00			`*x = Box::new(5);`
partially fix immediate rvalues The code generation previously assumed a reference could not alter the value in a way the destructor would notice. This is an incorrect assumption for `&mut`, and is also incorrect for an `&` pointer to a non-`Freeze` type. Closes #7972 2013-10-17 07:43:22 +00:00			`}`
