tests: Add missing run-pass annotations 2019-07-26 21:54:25 +00:00			`//@ run-pass`

test: De-mut the test suite. rs=demuting 2013-02-23 00:08:16 +00:00			`fn f(arg: &mut A) {`
Properly implement copy expressions (And use them in some places that were doing {expr} before.) 2011-09-12 11:13:20 +00:00			`arg.a = 100;`

Fallout in tests 2015-03-30 13:38:27 +00:00			`#[derive(Copy, Clone)]`
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			`struct A { a: isize }`
testsuite: Eliminate uses of structural records from most run-pass tests Except the pipes tests (that needs a snapshot) 2013-01-26 06:46:32 +00:00
check-fast fallout from removing export, r=burningtree 2013-02-02 03:43:17 +00:00			`pub fn main() {`

Use assert_eq! rather than assert! where possible 2013-05-19 02:02:45 +00:00			`assert_eq!(x.a, 100);`

librustc: Add a lint mode for unnecessary `copy` and remove a bunch of them. 2013-06-28 00:41:35 +00:00			`let mut y = x;`
