The field are always re-ordered to minimize padding, regardless of the alignment of the discriminant
This commit changes some usage of mem::forget into mem::ManuallyDrop in some Vec, VecDeque, BTreeMap and Box methods. Before the commit, the generated IR for some of the methods was longer, and even after optimization, some unwinding artifacts were still present.
rustc_target: Some cleanup to `no_default_libraries`
Do not disable field reordering on enums with big discriminant The field are always re-ordered to minimize padding, regardless of the alignment of the discriminant (spinoff from rust-lang#70477)
Match options directly in the Fuse implementation Rather than using `as_ref()`, `as_mut()`, and `?`, we can use `match` directly to save a lot of generated code. This was mentioned as a possibility in rust-lang#70366 (comment), and I found that it had a very large impact on rust-lang#70332 using `Fuse` within `Chain`. Let's evaluate this change on its own first.
…Mark-Simulacrum,RalfJung use ManuallyDrop instead of forget inside collections This PR changes some usage of `mem::forget` into `mem::ManuallyDrop` in some `Vec`, `VecDeque`, `BTreeMap` and `Box` methods. Before the commit, the generated IR for some of the methods was longer, and even after optimization, some unwinding artifacts were still present.
