tests: Add missing run-pass annotations 2019-07-27 00:54:25 +03:00			`// run-pass`

Allow various lints as part of ui-ifying `src/test/run-pass` suite. 2018-09-14 12:20:28 +02:00			`#![allow(dead_code)]`
Make last-use pass properly handle closed-over variables Closes #1399 2012-01-02 10:20:58 +01:00			`// Make sure #1399 stays fixed`

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			`#![feature(box_syntax)]`

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			`struct A { a: Box<isize> }`
testsuite: Eliminate uses of structural records from most run-pass tests Except the pipes tests (that needs a snapshot) 2013-01-25 22:46:32 -08:00
check-fast fallout from removing export, r=burningtree 2013-02-01 19:43:17 -08:00			`pub fn main() {`

Add `: Box<_>` or `::Box<_>` type annotations to various places. This is the kind of change that one is expected to need to make to accommodate overloaded-`box`. ---- Note that this is not all of the changes necessary to accommodate Issue 22181. It is merely the subset of those cases where there was already a let-binding in place that made it easy to add the necesasry type ascription. (For unnamed intermediate `Box` values, one must go down a different route; `Box::new` is the option that maximizes portability, but has potential inefficiency depending on whether the call is inlined.) ---- There is one place worth note, `run-pass/coerce-match.rs`, where I used an ugly form of `Box<_>` type ascription where I would have preferred to use `Box::new` to accommodate overloaded-`box`. I deliberately did not use `Box::new` here, because that is already done in coerce-match-calls.rs. ---- Precursor for overloaded-`box` and placement-`in`; see Issue 22181. 2015-02-17 21:41:32 +01:00			`let k: Box<_> = box 22;`
