Final SR - promised :) - <https://github.com/rust-lang/rust/issues/74976>: Add "--stage 1" to the "./x.py doc" call to ensure the newly built compiler gets used. ------------------------------------------------------------------- Sat Jan 9 09:25:07 UTC 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 3 11:27:23 UTC 2021 - Manfred Hollstein <manfred.h@gmx.net> - LLVM >= 9.0 is needed nowadays. - Disable usage of "ninja" for all distributions older than Leap 15.2 ------------------------------------------------------------------- Sat Jan 2 16:50:47 UTC 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: + ignore-Wstring-conversion.patch (location) OBS-URL: https://build.opensuse.org/request/show/862086 OBS-URL: https://build.opensuse.org/package/show/devel:languages:rust/rust?expand=0&rev=272
