Add edition checks for some tests that had divergent output

2025-06-25T17:02:26+00:00

In order to expose edition dependent divergences in some tests in the test suite, add explicit `edition` annotations. Some of these tests might require additional work to *avoid* the divergences, as they might have been unintentional. These are not exhaustive changes, purely opportunistic while looking at something else.

Do not use `gen` as binding name

2025-06-25T16:52:31+00:00

If we ever start testing every edition, using a new keyword unnecessarily will cause divergent output, so pre-emptively change `gen` into `generator`.

Unimplement unsized_locals Implements https://github.com/rust-lang/compiler-team/issues/630 Tracking issue here: https://github.com/rust-lang/rust/issues/111942 Note that this just removes the feature, not the implementation, and does not touch `unsized_fn_params`. This is because it is required to support `Box: FnOnce()`. There may be more that should be removed (possibly in follow up prs) - the `forget_unsized` function and `forget` intrinsic. - the `unsized_locals` test directory; I've just fixed up the tests for now - various codegen support for unsized values and allocas cc ``@JakobDegen`` ``@oli-obk`` ``@Noratrieb`` ``@programmerjake`` ``@bjorn3`` ``@rustbot`` label F-unsized_locals Fixes rust-lang/rust#79409

Update tests.

Add `iter` macro

2025-06-03T17:52:32+00:00

This adds an `iter!` macro that can be used to create movable generators. This also adds a yield_expr feature so the `yield` keyword can be used within iter! macro bodies. This was needed because several unstable features each need `yield` expressions, so this allows us to stabilize them separately from any individual feature.

Add missing `dyn` keywords to tests that do not test for them

This ensures that these tests can be run on editions other than 2015
