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`
fallout: run-pass tests that use box. (many could be ported to `Box::new` instead in the future.) 2015-01-08 01:25:56 +00:00			`#![feature(box_syntax)]`
Gate literal box expressions in addition to types Closes #10920 2013-12-12 07:17:54 +00:00
Mass rename uint/int to usize/isize Now that support has been removed, all lingering use cases are renamed. 2015-03-26 00:06:52 +00:00			`fn foo(x: &usize) -> &usize { x }`
			`fn bar(x: &usize) -> usize { *x }`

check-fast fallout from removing export, r=burningtree 2013-02-02 03:43:17 +00:00			`pub fn main() {`
Remove integer suffixes where the types in compiled code are identical. 2015-03-03 08:42:26 +00:00			`let p: Box<_> = box 3;`
librustc: Remove cross-borrowing of `Box<T>` to `&T` from the language, except where trait objects are involved. Part of issue #15349, though I'm leaving it open for trait objects. Cross borrowing for trait objects remains because it is needed until we have DST. This will break code like: fn foo(x: &int) { ... } let a = box 3i; foo(a); Change this code to: fn foo(x: &int) { ... } let a = box 3i; foo(&*a); [breaking-change] 2014-07-07 23:35:15 +00:00			`assert_eq!(bar(foo(&*p)), 3);`
