- Update to version 1.53:
+ Language
- [You can now use unicode for identifiers.][83799] This allows multilingual
identifiers but still doesn't allow glyphs that are not considered characters
such as `◆` or `🦀`. More specifically you can now use any identifier that
matches the UAX #31 "Unicode Identifier and Pattern Syntax" standard. This
is the same standard as languages like Python, however Rust uses NFC
normalization which may be different from other languages.
- [You can now specify "or patterns" inside pattern matches.][79278]
Previously you could only use `|` (OR) on complete patterns. E.g.
```rust
let x = Some(2u8);
// Before
matches!(x, Some(1) | Some(2));
// Now
matches!(x, Some(1 | 2));
```
- [Added the `:pat_param` `macro_rules!` matcher.][83386] This matcher
has the same semantics as the `:pat` matcher. This is to allow `:pat`
to change semantics to being a pattern fragment in a future edition.
+ Compiler
- [Updated the minimum external LLVM version to LLVM 10.][83387]
- [Added Tier 3\* support for the `wasm64-unknown-unknown` target.][80525]
- [Improved debuginfo for closures and async functions on Windows MSVC.][83941]
\* Refer to Rust's [platform support page][platform-support-doc] for more
information on Rust's tiered platform support.
+ Libraries
- [Abort messages will now forward to `android_set_abort_message` on
Android platforms when available.][81469]
- [`slice::IterMut<'_, T>` now implements `AsRef<[T]>`][82771]
- [Arrays of any length now implement `IntoIterator`.][84147]
Currently calling `.into_iter()` as a method on an array will
return `impl Iterator<Item=&T>`, but this may change in a
future edition to change `Item` to `T`. Calling `IntoIterator::into_iter`
directly on arrays will provide `impl Iterator<Item=T>` as expected.
- [`leading_zeros`, and `trailing_zeros` are now available on all
`NonZero` integer types.][84082]
- [`{f32, f64}::from_str` now parse and print special values
(`NaN`, `-0`) according to IEEE RFC 754.][78618]
- [You can now index into slices using `(Bound<usize>, Bound<usize>)`.][77704]
- [Add the `BITS` associated constant to all numeric types.][82565]
+ Cargo
- [Cargo now supports git repositories where the default `HEAD` branch is not
"master".][cargo/9392] This also includes a switch to the version 3 `Cargo.lock` format
which can handle default branches correctly.
- [macOS targets now default to `unpacked` split-debuginfo.][cargo/9298]
- [The `authors` field is no longer included in `Cargo.toml` for new
projects.][cargo/9282]
+ Rustdoc
- [Added the `rustdoc::bare_urls` lint that warns when you have URLs
without hyperlinks.][81764]
+ Compatibility Notes
- [Implement token-based handling of attributes during expansion][82608]
- [`Ipv4::from_str` will now reject octal format IP addresses in addition
to rejecting hexadecimal IP addresses.][83652] The octal format can lead
to confusion and potential security vulnerabilities and [is no
longer recommended][ietf6943].
* Mon May 10 2021 William Brown <william.brown@suse.com>
- Update to version 1.52.1:
- This release works around broken builds on 1.52.0, which are caused by newly
added verification. The bugs this verification detects are present in all
Rust versions, and can trigger miscompilations in incremental builds, so
downgrading to a prior stable version is not a fix.
- What should a Rust programmer do in response?
- upgrade to 1.52.1
- deleting your incremental compilation cache (e.g. by running cargo clean)
- forcing incremental compilation to be disabled, by setting
CARGO_INCREMENTAL=0 in your environment or build.incremental to false in
the config.toml.
- For more: https://blog.rust-lang.org/2021/05/10/Rust-1.52.1.html
* Fri May 07 2021 William Brown <william.brown@suse.com>
- Update to version 1.52:
+ Language
- [Added the `unsafe_op_in_unsafe_fn` lint, which checks whether the unsafe code
in an `unsafe fn` is wrapped in a `unsafe` block.][79208] This lint
is allowed by default, and may become a warning or hard error in a
future edition.
- [You can now cast mutable references to arrays to a pointer of the same type as
the element.][81479]
+ Compiler
- [Upgraded the default LLVM to LLVM 12.][81451]
- Added tier 3\* support for the following targets.
- [`s390x-unknown-linux-musl`][82166]
- [`riscv32gc-unknown-linux-musl` & `riscv64gc-unknown-linux-musl`][82202]
- [`powerpc-unknown-openbsd`][82733]
+ Libraries
- [`OsString` now implements `Extend` and `FromIterator`.][82121]
- [`cmp::Reverse` now has `#[repr(transparent)]` representation.][81879]
- [`Arc<impl Error>` now implements `error::Error`.][80553]
- [All integer division and remainder operations are now `const`.][80962]
+ Stabilised APIs
- [`Arguments::as_str`]
- [`char::MAX`]
- [`char::REPLACEMENT_CHARACTER`]
- [`char::UNICODE_VERSION`]
- [`char::decode_utf16`]
- [`char::from_digit`]
- [`char::from_u32_unchecked`]
- [`char::from_u32`]
- [`slice::partition_point`]
- [`str::rsplit_once`]
- [`str::split_once`]
The following previously stable APIs are now `const`.
- [`char::len_utf8`]
- [`char::len_utf16`]
- [`char::to_ascii_uppercase`]
- [`char::to_ascii_lowercase`]
- [`char::eq_ignore_ascii_case`]
- [`u8::to_ascii_uppercase`]
- [`u8::to_ascii_lowercase`]
- [`u8::eq_ignore_ascii_case`]
+ Rustdoc
- [Rustdoc lints are now treated as a tool lint, meaning that
lints are now prefixed with `rustdoc::` (e.g. `#[warn(rustdoc::non_autolinks)]`).][80527]
Using the old style is still allowed, and will become a warning in
a future release.
- [Rustdoc now supports argument files.][82261]
- [Rustdoc now generates smart punctuation for documentation.][79423]
- [You can now use "task lists" in Rustdoc Markdown.][81766] E.g.
```markdown
- [x] Complete
- [ ] Todo
```
+ Misc
- [You can now pass multiple filters to tests.][81356] E.g.
`cargo test -- foo bar` will run all tests that match `foo` and `bar`.
- [Rustup now distributes PDB symbols for the `std` library on Windows,
allowing you to see `std` symbols when debugging.][82218]
+ Internal Only
These changes provide no direct user facing benefits, but represent significant
improvements to the internals and overall performance of rustc and
related tools.
- [Check the result cache before the DepGraph when ensuring queries][81855]
- [Try fast_reject::simplify_type in coherence before doing full check][81744]
- [Only store a LocalDefId in some HIR nodes][81611]
- [Store HIR attributes in a side table][79519]
+ Compatibility Notes
- ------------------
- [Cargo build scripts are now forbidden from setting `RUSTC_BOOTSTRAP`.][cargo/9181]
- [Removed support for the `x86_64-rumprun-netbsd` target.][82594]
- [Deprecated the `x86_64-sun-solaris` target in favor of `x86_64-pc-solaris`.][82216]
- [Rustdoc now only accepts `,`, ` `, and `\t` as delimiters for specifying
languages in code blocks.][78429]
- [Rustc now catches more cases of `pub_use_of_private_extern_crate`][80763]
- [Changes in how proc macros handle whitespace may lead to panics when used
with older `proc-macro-hack` versions. A `cargo update` should be sufficient to fix
this in all cases.][84136]
- Remove support-llvm12.patch - feature of 1.52
* Sat Apr 17 2021 Aaron Puchert <aaronpuchert@alice-dsl.net>
- Add support-llvm12.patch to support building with LLVM 12.
* Tue Apr 06 2021 William Brown <william.brown@suse.com>
- Update to version 1.51:
+ Language
- [You can now parameterize items such as functions, traits, and `struct`s by constant
values in addition to by types and lifetimes.][79135] Also known as "const generics"
E.g. you can now write the following. Note: Only values of primitive integers,
`bool`, or `char` types are currently permitted.
+ Compiler
- [Added the `-Csplit-debuginfo` codegen option for macOS platforms.][79570]
This option controls whether debug information is split across multiple files
or packed into a single file. **Note** This option is unstable on other platforms.
- [Added tier 3\* support for `aarch64_be-unknown-linux-gnu`,
`aarch64-unknown-linux-gnu_ilp32`, and `aarch64_be-unknown-linux-gnu_ilp32` targets.][81455]
- [Added tier 3 support for `i386-unknown-linux-gnu` and `i486-unknown-linux-gnu` targets.][80662]
- [The `target-cpu=native` option will now detect individual features of CPUs.][80749]
\* Refer to Rust's [platform support page][platform-support-doc] for more
information on Rust's tiered platform support.
+ Libraries
- [`Box::downcast` is now also implemented for any `dyn Any + Send + Sync` object.][80945]
- [`str` now implements `AsMut<str>`.][80279]

+ Cargo
- [Added the `split-debuginfo` profile option to control the -Csplit-debuginfo
codegen option.][cargo/9112]
- [Added the `resolver` field to `Cargo.toml` to enable the new feature resolver
and CLI option behavior.][cargo/8997] Version 2 of the feature resolver will try
to avoid unifying features of dependencies where that unification could be unwanted.
Such as using the same dependency with a `std` feature in a build scripts and
proc-macros, while using the `no-std` feature in the final binary. See the
[Cargo book documentation][feature-resolver@2.0] for more information on the feature.
+ Rustdoc
- [Rustdoc will now include documentation for methods available from _nested_ `Deref` traits.][80653]
- [You can now provide a `--default-theme` flag which sets the default theme to use for
documentation.][79642]
Various improvements to intra-doc links:
- [You can link to non-path primitives such as `slice`.][80181]
- [You can link to associated items.][74489]
- [You can now include generic parameters when linking to items, like `Vec<T>`.][76934]
+ Misc
- [You can now pass `--include-ignored` to tests (e.g. with
`cargo test -- --include-ignored`) to include testing tests marked `#[ignore]`.][80053]
+ Compatibility Notes
- [WASI platforms no longer use the `wasm-bindgen` ABI, and instead use the wasm32 ABI.][79998]
- [`rustc` no longer promotes division, modulo and indexing operations to `const` that
could fail.][80579]
- [The minimum version of glibc for the following platforms has been bumped to version 2.31
for the distributed artifacts.][81521]
- `armv5te-unknown-linux-gnueabi`
- `sparc64-unknown-linux-gnu`
- `thumbv7neon-unknown-linux-gnueabihf`

* Wed Feb 24 2021 Guillaume GARDET <guillaume.gardet@opensuse.org>
- Update to version 1.50:
* This fixes build on armv7 - boo#1181643
+ Language
- You can now use const values for x in [x; N] array expressions.
This has been technically possible since 1.38.0, as it was
unintentionally stabilized.
- Assignments to ManuallyDrop<T> union fields are now considered safe.
+ Compiler
- Added tier 3* support for the armv5te-unknown-linux-uclibceabi
target.

- The x86_64-unknown-freebsd is now built with the full toolset.
- Dropped support for all cloudabi targets.
* Refer to Rust's platform support page for more information on
Rust's tiered platform support.
+ Libraries
- proc_macro::Punct now implements PartialEq<char>.
- ops::{Index, IndexMut} are now implemented for fixed sized
arrays of any length.
- On Unix platforms, the std::fs::File type now has a "niche" of -1.
This value cannot be a valid file descriptor, and now means Option<File>
takes up the same amount of space as File.
+ Stabilized APIs

+ Cargo
- Added the [build.rustc-workspace-wrapper] option. This option
sets a wrapper to execute instead of rustc, for workspace members only.
- cargo:rerun-if-changed will now, if provided a directory,
scan the entire contents of that directory for changes.
- Added the --workspace flag to the cargo update command.
+ Misc
- The search results tab and the help button are focusable
with keyboard in rustdoc.
- Running tests will now print the total time taken to execute.
+ Compatibility Notes
- The compare_and_swap method on atomics has been deprecated.
It's recommended to use the compare_exchange and
compare_exchange_weak methods instead.
- Changes in how TokenStreams are checked have fixed some cases
where you could write unhygenic macro_rules! macros.
- #![test] as an inner attribute is now considered unstable
like other inner macro attributes, and reports an error by
default through the soft_unstable lint.
- Overriding a forbid lint at the same level that it was set
is now a hard error.
- You can no longer intercept panic! calls by supplying your own
macro. It's recommended to use the #[panic_handler] attribute
to provide your own implementation.
- Semi-colons after item statements (e.g. struct Foo {};)
now produce a warning.
* Sun Jan 10 2021 Neal Gompa <ngompa13@gmail.com>

to the "./x.py doc" call to ensure the newly built compiler gets
used.
* Sat Jan 09 2021 Manfred Hollstein <manfred.h@gmx.net>
- Leap 15.3 does not provide a suitable llvm-devel package, hence
explicitly require llvm9-devel. Details can be seen in the following
e-mail thread
<https://lists.opensuse.org/archives/list/factory@lists.opensuse.org/thread/ZQWAMG2VYBSI2BFM7G3H5YG26ALXWAOA/>
* Sun Jan 03 2021 Manfred Hollstein <manfred.h@gmx.net>
- Update to version 1.49.0
+ Language
- Unions can now implement Drop, and you can now have a field in
a union with ManuallyDrop<T>.
- You can now cast uninhabited enums to integers.
- You can now bind by reference and by move in patterns. This
allows you to selectively borrow individual components of a type.
E.g.
[#][derive(Debug)]
struct Person {
name: String,
age: u8,
}
let person = Person {
name: String::from("Alice"),
age: 20,
};
// `name` is moved out of person, but `age` is referenced.
let Person { name, ref age } = person;
println!("{} {}", name, age);
+ Compiler
- Added tier 1* support for aarch64-unknown-linux-gnu.
- Added tier 2 support for aarch64-apple-darwin.
- Added tier 2 support for aarch64-pc-windows-msvc.
- Added tier 3 support for mipsel-unknown-none.

indexing.
- ToString::to_string now no longer shrinks the internal buffer in
the default implementation.
- ops::{Index, IndexMut} are now implemented for fixed sized arrays
of any length.

- You can now use glob patterns when specifying packages & targets.
+ Compatibility Notes
- Demoted i686-unknown-freebsd from host tier 2 to target tier 2
support.
- Macros that end with a semi-colon are now treated as statements
even if they expand to nothing.
- Rustc will now check for the validity of some built-in attributes
on enum variants. Previously such invalid or unused attributes
could be ignored.
- Leading whitespace is stripped more uniformly in documentation
comments, which may change behavior. You read this post about
the changes for more details.
- Trait bounds are no longer inferred for associated types.
+ Internal Only
These changes provide no direct user facing benefits, but
represent significant improvements to the internals and overall
performance of rustc and related tools.
- rustc's internal crates are now compiled using the initial-exec
Thread Local Storage model.
- Calculate visibilities once in resolve.

- LLVM >= 9.0 is needed nowadays.
- Disable usage of "ninja" for all distributions older than Leap 15.2
* Sat Jan 02 2021 Manfred Hollstein <manfred.h@gmx.net>
- Update to version 1.48.0
+ Language
- The `unsafe` keyword is now syntactically permitted on modules.
This is still rejected semantically, but can now be parsed by procedural
macros.
+ Compiler
- Stabilised the `-C link-self-contained=<yes|no>` compiler flag.
This tells `rustc` whether to link its own C runtime and libraries or to
rely on a external linker to find them. (Supported only on `windows-gnu`,
`linux-musl`, and `wasi` platforms.)
- You can now use `-C target-feature=+crt-static` on `linux-gnu` targets.
Note: If you're using cargo you must explicitly pass the `--target` flag.
- Added tier 2* support for aarch64-unknown-linux-musl.
* Refer to Rust's platform support page for more information on Rust's
tiered platform support.
+ Libraries
- io::Write is now implemented for &ChildStdin &Sink, &Stdout, and &Stderr.
- All arrays of any length now implement TryFrom<Vec<T>>.
- The matches! macro now supports having a trailing comma.
- Vec<A> now implements PartialEq<[B]> where A: PartialEq<B>.
- The RefCell::{replace, replace_with, clone} methods now all use #[track_caller].
+ Stabilized APIs
- slice::as_ptr_range
- slice::as_mut_ptr_range
- VecDeque::make_contiguous
- future::pending
- future::ready
The following previously stable methods are now `const fn's`:
- Option::is_some
- Option::is_none
- Option::as_ref
- Result::is_ok
- Result::is_err
- Result::as_ref
- Ordering::reverse
- Ordering::then
+ Cargo
+ Rustdoc
- You can now link to items in rustdoc using the intra-doc link syntax.
E.g. /// Uses [`std::future`] will automatically generate a link to
std::future's documentation. See "Linking to items by name" for more
information.
- You can now specify #[doc(alias = "<alias>")] on items to add search
aliases when searching through rustdoc's UI.
+ Compatibility Notes
- Promotion of references to 'static lifetime inside const fn now
follows the same rules as inside a fn body. In particular, &foo()
will not be promoted to 'static lifetime any more inside const fns.
- Associated type bindings on trait objects are now verified to meet
the bounds declared on the trait when checking that they implement
the trait.
- When trait bounds on associated types or opaque types are ambiguous,
the compiler no longer makes an arbitrary choice on which bound to use.
- Fixed recursive nonterminals not being expanded in macros during
pretty-print/reparse check. This may cause errors if your macro
wasn't correctly handling recursive nonterminal tokens.
- &mut references to non zero-sized types are no longer promoted.
- rustc will now warn if you use attributes like #[link_name] or
[#][cold] in places where they have no effect.
- Updated _mm256_extract_epi8 and _mm256_extract_epi16 signatures
in arch::{x86, x86_64} to return i32 to match the vendor signatures.
- mem::uninitialized will now panic if any inner types inside a struct
or enum disallow zero-initialization.
- #[target_feature] will now error if used in a place where it has no effect.
- Foreign exceptions are now caught by catch_unwind and will cause an
abort. Note: This behaviour is not guaranteed and is still considered
undefined behaviour, see the catch_unwind documentation for further
information.
+ Internal Only
These changes provide no direct user facing benefits, but represent
significant improvements to the internals and overall performance of
rustc and related tools.
- Building rustc from source now uses ninja by default over make.
You can continue building with make by setting ninja=false in
your config.toml.
- cg_llvm: fewer_names in uncached_llvm_type
- Made ensure_sufficient_stack() non-generic
- Rebased patches:
