Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @estebank (or someone else) soon.

If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

Please see the contribution instructions for more information.

These commits modify submodules.

davidlt · 2019-02-12T18:08:31Z

Silly question, would this allow me building Rust on riscv64 host, or does it only enable riscv64 (rv64gc) as a target where host is, e.g., x86_64?

jethrogb · 2019-02-12T18:11:10Z

@davidlt No, for that you'd need to add a riscv64gc-unknown-linux-gnu target.

jethrogb · 2019-02-12T18:18:37Z

Please also file a PR against https://github.com/rust-lang/rust-forge/ for https://forge.rust-lang.org/platform-support.html

Pkgsrc changes: * Bump required rust version to build to 1.33.0. * Adapt patches to changed file locations. * (I worry about 32-bit ports, now that Atomic64 apparently is First-Class; this has been built on NetBSD/amd64 so far) Upstream changes: Version 1.34.0 (2019-04-11) ========================== Language -------- - [You can now use `#[deprecated = "reason"]`][58166] as a shorthand for `#[deprecated(note = "reason")]`. This was previously allowed by mistake but had no effect. - [You can now accept token streams in `#[attr()]`,`#[attr[]]`, and `#[attr{}]` procedural macros.][57367] - [You can now write `extern crate self as foo;`][57407] to import your crate's root into the extern prelude. Compiler -------- - [You can now target `riscv64imac-unknown-none-elf` and `riscv64gc-unknown-none-elf`.][58406] - [You can now enable linker plugin LTO optimisations with `-C linker-plugin-lto`.][58057] This allows rustc to compile your Rust code into LLVM bitcode allowing LLVM to perform LTO optimisations across C/C++ FFI boundaries. - [You can now target `powerpc64-unknown-freebsd`.][57809] Libraries --------- - [The trait bounds have been removed on some of `HashMap<K, V, S>`'s and `HashSet<T, S>`'s basic methods.][58370] Most notably you no longer require the `Hash` trait to create an iterator. - [The `Ord` trait bounds have been removed on some of `BinaryHeap<T>`'s basic methods.][58421] Most notably you no longer require the `Ord` trait to create an iterator. - [The methods `overflowing_neg` and `wrapping_neg` are now `const` functions for all numeric types.][58044] - [Indexing a `str` is now generic over all types that implement `SliceIndex<str>`.][57604] - [`str::trim`, `str::trim_matches`, `str::trim_{start, end}`, and `str::trim_{start, end}_matches` are now `#[must_use]`][57106] and will produce a warning if their returning type is unused. - [The methods `checked_pow`, `saturating_pow`, `wrapping_pow`, and `overflowing_pow` are now available for all numeric types.][57873] These are equivalvent to methods such as `wrapping_add` for the `pow` operation. Stabilized APIs --------------- #### std & core * [`Any::type_id`] * [`Error::type_id`] * [`atomic::AtomicI16`] * [`atomic::AtomicI32`] * [`atomic::AtomicI64`] * [`atomic::AtomicI8`] * [`atomic::AtomicU16`] * [`atomic::AtomicU32`] * [`atomic::AtomicU64`] * [`atomic::AtomicU8`] * [`convert::Infallible`] * [`convert::TryFrom`] * [`convert::TryInto`] * [`iter::from_fn`] * [`iter::successors`] * [`num::NonZeroI128`] * [`num::NonZeroI16`] * [`num::NonZeroI32`] * [`num::NonZeroI64`] * [`num::NonZeroI8`] * [`num::NonZeroIsize`] * [`slice::sort_by_cached_key`] * [`str::escape_debug`] * [`str::escape_default`] * [`str::escape_unicode`] * [`str::split_ascii_whitespace`] #### std * [`Instant::checked_add`] * [`Instant::checked_sub`] * [`SystemTime::checked_add`] * [`SystemTime::checked_sub`] Cargo ----- - [You can now use alternative registries to crates.io.][cargo/6654] Misc ---- - [You can now use the `?` operator in your documentation tests without manually adding `fn main() -> Result<(), _> {}`.][56470] Compatibility Notes ------------------- - [`Command::before_exec` is now deprecated in favor of the unsafe method `Command::pre_exec`.][58059] - [Use of `ATOMIC_{BOOL, ISIZE, USIZE}_INIT` is now deprecated.][57425] As you can now use `const` functions in `static` variables.
