Add AArch64 big-endian and ILP32 targets #81455
Conversation
On big-endian the values need to be right-aligned within a 64-bit register, as if the value had been read with a 64-bit load instruction.

Make remote-test-server easier to use with new targets While testing rust-lang#81455 I encountered 2 issues with `remote-test-server`: - It is built with the stage 0 toolchain, which does not support a newly added target. - It overwrites `LD_LIBRARY_PATH` instead of appending to it, which prevents the use of a custom sysroot for target libraries.

Pkgsrc changes: * Remove one SunOS patch, apparently no longer needed. * Adapt one patch for Darwin, adjust cargo checksum accordingly. * Adjust bootstraps to version 1.50.0. Version 1.51.0 (2021-03-25) ============================ 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. ```rust struct GenericArray<T, const LENGTH: usize> { inner: [T; LENGTH] } impl<T, const LENGTH: usize> GenericArray<T, LENGTH> { const fn last(&self) -> Option<&T> { if LENGTH == 0 { None } else { Some(&self.inner[LENGTH - 1]) } } } ``` 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] - [Rust now uses `inline-asm` for stack probes when used with LLVM 11.0.1+][77885] \* Refer to Rust's [platform support page][forge-platform-support] for more information on Rust's tiered platform support.

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][[email protected]] for more information on the feature. Rustdoc ------- - [Rustdoc will now include documentation for methods available from `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` - `armv7-unknown-linux-gnueabi` - `x86_64-unknown-linux-gnux32` Internal Only ------------- - [Consistently avoid constructing optimized MIR when not doing codegen][80718] [79135]: rust-lang/rust#79135 [74489]: rust-lang/rust#74489 [76934]: rust-lang/rust#76934 [79570]: rust-lang/rust#79570 [80181]: rust-lang/rust#80181 [79642]: rust-lang/rust#79642 [80945]: rust-lang/rust#80945 [80279]: rust-lang/rust#80279 [80053]: rust-lang/rust#80053 [79502]: rust-lang/rust#79502 [75180]: rust-lang/rust#75180 [79135]: rust-lang/rust#79135 [81521]: rust-lang/rust#81521 [80968]: rust-lang/rust#80968 [80959]: rust-lang/rust#80959 [80718]: rust-lang/rust#80718 [80653]: rust-lang/rust#80653 [80579]: rust-lang/rust#80579 [79998]: rust-lang/rust#79998 [78044]: rust-lang/rust#78044 [81455]: rust-lang/rust#81455 [80764]: rust-lang/rust#80764 [80749]: rust-lang/rust#80749 [80662]: rust-lang/rust#80662 [77885]: rust-lang/rust#77885 [cargo/8997]: rust-lang/cargo#8997 [cargo/9112]: rust-lang/cargo#9112 [[email protected]]: https://doc.rust-lang.org/nightly/cargo/reference/features.html#feature-resolver-version-2 [`Once::call_once_force`]: https://doc.rust-lang.org/stable/std/sync/struct.Once.html#method.call_once_force [`sync::OnceState`]: https://doc.rust-lang.org/stable/std/sync/struct.OnceState.html [`panic::panic_any`]: https://doc.rust-lang.org/stable/std/panic/fn.panic_any.html [`slice::strip_prefix`]: https://doc.rust-lang.org/stable/std/primitive.slice.html#method.strip_prefix [`slice::strip_suffix`]: https://doc.rust-lang.org/stable/std/primitive.slice.html#method.strip_prefix [`Arc::increment_strong_count`]: https://doc.rust-lang.org/nightly/std/sync/struct.Arc.html#method.increment_strong_count [`Arc::decrement_strong_count`]: https://doc.rust-lang.org/nightly/std/sync/struct.Arc.html#method.decrement_strong_count [`slice::fill_with`]: https://doc.rust-lang.org/nightly/std/primitive.slice.html#method.fill_with [`ptr::addr_of!`]: https://doc.rust-lang.org/nightly/std/ptr/macro.addr_of.html [`ptr::addr_of_mut!`]: https://doc.rust-lang.org/nightly/std/ptr/macro.addr_of_mut.html [`array::IntoIter`]: https://doc.rust-lang.org/nightly/std/array/struct.IntoIter.html [`slice::split_inclusive`]: https://doc.rust-lang.org/nightly/std/primitive.slice.html#method.split_inclusive [`slice::split_inclusive_mut`]: https://doc.rust-lang.org/nightly/std/primitive.slice.html#method.split_inclusive_mut [`str::split_inclusive`]: https://doc.rust-lang.org/nightly/std/primitive.str.html#method.split_inclusive [`task::Wake`]: https://doc.rust-lang.org/nightly/std/task/trait.Wake.html [`Seek::stream_position`]: https://doc.rust-lang.org/nightly/std/io/trait.Seek.html#method.stream_position [`Peekable::next_if`]: https://doc.rust-lang.org/nightly/std/iter/struct.Peekable.html#method.next_if [`Peekable::next_if_eq`]: https://doc.rust-lang.org/nightly/std/iter/struct.Peekable.html#method.next_if_eq
Pkgsrc changes: * Add support for the big-endian arm64 NetBSD target (aarch64_be). * On NetBSD/i386, use the i586 (pentium) bootstrap kit variant in preference to i686. * Adjust patches, re-compute line offsets, re-compute crate checksums. * Remove a patch which was either integrated upstream and/or no longer applies. * Bump bootstraps to 1.50.0. * Move conditionals until after bsd.prefs.mk so that they work... * Default to "dist" build target if cross-compiling, but allow also to override via rust.BUILD_TARGET. * Allow overriding MAKE_JOBS_SAFE via rust.MAKE_JOBS_SAFE if you want a different trade-off between occasional breakage and performance. * Adjust platform.mk according to work already done in wip/rust/ * Add a patch to optimize the install.sh script used to install binary bootstraps to not do so many forks; use case/esac and parameter expansion instead of grep, sed and cut. * Drop building documentation for the binary bootstrap kits. This will also impact the lang/rust-bin package. For full documentation, build or install lang/rust as a package.
