If this works I think we should consider backporting since the regression is currently visible with a segfault on stable. |

We were missing an Instance::resolve_for_fn_ptr in resolve_for_vtable. Closes rust-lang#74764.

While here clean up all pkglint warnings. Changes since 1.44.1: Version 1.45.2 (2020-08-03) ========================== * [Fix bindings in tuple struct patterns][74954] * [Fix track_caller integration with trait objects][74784] [74954]: rust-lang/rust#74954 [74784]: rust-lang/rust#74784 Version 1.45.1 (2020-07-30) ========================== * [Fix const propagation with references.][73613] * [rustfmt accepts rustfmt_skip in cfg_attr again.][73078] * [Avoid spurious implicit region bound.][74509] * [Install clippy on x.py install][74457] [73613]: rust-lang/rust#73613 [73078]: rust-lang/rust#73078 [74509]: rust-lang/rust#74509 [74457]: rust-lang/rust#74457 Version 1.45.0 (2020-07-16) ========================== Language -------- - [Out of range float to int conversions using `as` has been defined as a saturating conversion.][71269] This was previously undefined behaviour, but you can use the `{f64, f32}::to_int_unchecked` methods to continue using the current behaviour, which may be desirable in rare performance sensitive situations. - [`mem::Discriminant<T>` now uses `T`'s discriminant type instead of always using `u64`.][70705] - [Function like procedural macros can now be used in expression, pattern, and statement positions.][68717] This means you can now use a function-like procedural macro anywhere you can use a declarative (`macro_rules!`) macro. Compiler -------- - [You can now override individual target features through the `target-feature` flag.][72094] E.g. `-C target-feature=+avx2 -C target-feature=+fma` is now equivalent to `-C target-feature=+avx2,+fma`. - [Added the `force-unwind-tables` flag.][69984] This option allows rustc to always generate unwind tables regardless of panic strategy. - [Added the `embed-bitcode` flag.][71716] This codegen flag allows rustc to include LLVM bitcode into generated `rlib`s (this is on by default). - [Added the `tiny` value to the `code-model` codegen flag.][72397] - [Added tier 3 support\* for the `mipsel-sony-psp` target.][72062] - [Added tier 3 support for the `thumbv7a-uwp-windows-msvc` target.][72133] \* Refer to Rust's [platform support page][forge-platform-support] for more information on Rust's tiered platform support. Libraries --------- - [`net::{SocketAddr, SocketAddrV4, SocketAddrV6}` now implements `PartialOrd` and `Ord`.][72239] - [`proc_macro::TokenStream` now implements `Default`.][72234] - [You can now use `char` with `ops::{Range, RangeFrom, RangeFull, RangeInclusive, RangeTo}` to iterate over a range of codepoints.][72413] E.g. you can now write the following; ```rust for ch in 'a'..='z' { print!("{}", ch); } println!(); // Prints "abcdefghijklmnopqrstuvwxyz" ``` - [`OsString` now implements `FromStr`.][71662] - [The `saturating_neg` method as been added to all signed integer primitive types, and the `saturating_abs` method has been added for all integer primitive types.][71886] - [`Arc<T>`, `Rc<T>` now implement `From<Cow<'_, T>>`, and `Box` now implements `From<Cow>` when `T` is `[T: Copy]`, `str`, `CStr`, `OsStr`, or `Path`.][71447] - [`Box<[T]>` now implements `From<[T; N]>`.][71095] - [`BitOr` and `BitOrAssign` are implemented for all `NonZero` integer types.][69813] - [The `fetch_min`, and `fetch_max` methods have been added to all atomic integer types.][72324] - [The `fetch_update` method has been added to all atomic integer types.][71843] Stabilized APIs --------------- - [`Arc::as_ptr`] - [`BTreeMap::remove_entry`] - [`Rc::as_ptr`] - [`rc::Weak::as_ptr`] - [`rc::Weak::from_raw`] - [`rc::Weak::into_raw`] - [`str::strip_prefix`] - [`str::strip_suffix`] - [`sync::Weak::as_ptr`] - [`sync::Weak::from_raw`] - [`sync::Weak::into_raw`] - [`char::UNICODE_VERSION`] - [`Span::resolved_at`] - [`Span::located_at`] - [`Span::mixed_site`] - [`unix::process::CommandExt::arg0`] Cargo ----- Misc ---- - [Rustdoc now supports strikethrough text in Markdown.][71928] E.g. `~~outdated information~~` becomes "~~outdated information~~". - [Added an emoji to Rustdoc's deprecated API message.][72014] Compatibility Notes ------------------- - [Trying to self initialize a static value (that is creating a value using itself) is unsound and now causes a compile error.][71140] - [`{f32, f64}::powi` now returns a slightly different value on Windows.][73420] This is due to changes in LLVM's intrinsics which `{f32, f64}::powi` uses. - [Rustdoc's CLI's extra error exit codes have been removed.][71900] These were previously undocumented and not intended for public use. Rustdoc still provides a non-zero exit code on errors. Internals Only -------------- - [Make clippy a git subtree instead of a git submodule][70655] - [Unify the undo log of all snapshot types][69464] [73420]: rust-lang/rust#73420 [72324]: rust-lang/rust#72324 [71843]: rust-lang/rust#71843 [71886]: rust-lang/rust#71886 [72234]: rust-lang/rust#72234 [72239]: rust-lang/rust#72239 [72397]: rust-lang/rust#72397 [72413]: rust-lang/rust#72413 [72014]: rust-lang/rust#72014 [72062]: rust-lang/rust#72062 [72094]: rust-lang/rust#72094 [72133]: rust-lang/rust#72133 [71900]: rust-lang/rust#71900 [71928]: rust-lang/rust#71928 [71662]: rust-lang/rust#71662 [71716]: rust-lang/rust#71716 [71447]: rust-lang/rust#71447 [71269]: rust-lang/rust#71269 [71095]: rust-lang/rust#71095 [71140]: rust-lang/rust#71140 [70655]: rust-lang/rust#70655 [70705]: rust-lang/rust#70705 [69984]: rust-lang/rust#69984 [69813]: rust-lang/rust#69813 [69464]: rust-lang/rust#69464 [68717]: rust-lang/rust#68717 [`Arc::as_ptr`]: https://doc.rust-lang.org/stable/std/sync/struct.Arc.html#method.as_ptr [`BTreeMap::remove_entry`]: https://doc.rust-lang.org/stable/std/collections/struct.BTreeMap.html#method.remove_entry [`Rc::as_ptr`]: https://doc.rust-lang.org/stable/std/rc/struct.Rc.html#method.as_ptr [`rc::Weak::as_ptr`]: https://doc.rust-lang.org/stable/std/rc/struct.Weak.html#method.as_ptr [`rc::Weak::from_raw`]: https://doc.rust-lang.org/stable/std/rc/struct.Weak.html#method.from_raw [`rc::Weak::into_raw`]: https://doc.rust-lang.org/stable/std/rc/struct.Weak.html#method.into_raw [`sync::Weak::as_ptr`]: https://doc.rust-lang.org/stable/std/sync/struct.Weak.html#method.as_ptr [`sync::Weak::from_raw`]: https://doc.rust-lang.org/stable/std/sync/struct.Weak.html#method.from_raw [`sync::Weak::into_raw`]: https://doc.rust-lang.org/stable/std/sync/struct.Weak.html#method.into_raw [`str::strip_prefix`]: https://doc.rust-lang.org/stable/std/primitive.str.html#method.strip_prefix [`str::strip_suffix`]: https://doc.rust-lang.org/stable/std/primitive.str.html#method.strip_suffix [`char::UNICODE_VERSION`]: https://doc.rust-lang.org/stable/std/char/constant.UNICODE_VERSION.html [`Span::resolved_at`]: https://doc.rust-lang.org/stable/proc_macro/struct.Span.html#method.resolved_at [`Span::located_at`]: https://doc.rust-lang.org/stable/proc_macro/struct.Span.html#method.located_at [`Span::mixed_site`]: https://doc.rust-lang.org/stable/proc_macro/struct.Span.html#method.mixed_site [`unix::process::CommandExt::arg0`]: https://doc.rust-lang.org/std/os/unix/process/trait.CommandExt.html#tymethod.arg0
