bors f6faef4475 Auto merge of #114795 - RalfJung:cell-swap, r=dtolnay ... make Cell::swap panic if the Cells partially overlap The following function ought to be sound: ```rust fn as_cell_of_array<T, const N: usize>(c: &[Cell<T>; N]) -> &Cell<[T; N]> { unsafe { transmute(c) } } ``` However, due to `Cell::swap`, it currently is not -- safe code can [cause a use-after-free](https://play.rust-lang.org/?version=nightly&mode=debug&edition=2018&gist=c9415799722d985ff7d2c2c997b724ca). This PR fixes that. Fixes https://github.com/rust-lang/rust/issues/80778		2023-08-29 07:53:56 +00:00
