[AUTO-GENERATED] Migrate ui tests from `//` to `//@` directives 2024-02-16 20:02:50 +00:00			`//@ run-pass`
Rehabilitate an unboxed closure test This test works as a regression test for issue #17655. It also exercises mutation of by-ref upvars. 2014-10-02 19:48:07 -07:00			`fn each<'a,T,F:FnMut(&'a T)>(x: &'a [T], mut f: F) {`
`for x in xs.iter()` -> `for x in &xs` 2015-01-31 12:20:46 -05:00			`for val in x {`
librustc: Parse, but do not fully turn on, the `ref` keyword for by-reference upvars. This partially implements RFC 38. A snapshot will be needed to turn this on, because stage0 cannot yet parse the keyword. Part of #12381. 2014-07-23 12:43:29 -07:00			`f(val)`
			`}`

			`fn main() {`
Remove integer suffixes where the types in compiled code are identical. 2015-03-03 10:42:26 +02:00			`let mut sum = 0;`
			`let elems = [ 1, 2, 3, 4, 5 ];`
Mass rename uint/int to usize/isize Now that support has been removed, all lingering use cases are renamed. 2015-03-25 17:06:52 -07:00			`each(&elems, \|val: &usize\| sum += *val);`
