to NetBSD/pkgsrc
that referenced
this pull request
Nov 13, 2020
Pkgsrc changes:
* Remove patches now integrated upstream, many related to SunOS / Illumos.
* The LLVM fix for powerpc is also now integrated upstream.
* Adapt those patches where the source has moved or parts are integrated.
* The randomness patches no longer applies, and I could not find
where those files went...
* Provide a separate bootstrap for NetBSD/powerpc 9.0, since apparently
the C++ ABI is different from 8.0. Yes, this appears to be specific to
the NetBSD powerpc ports.
Upstream changes:
Version 1.47.0 (2020-10-08)
==========================
Language
--------
- [Closures will now warn when not used.][74869]
Compiler
--------
- [Stabilized the `-C control-flow-guard` codegen option][73893], which enables
[Control Flow Guard][1.47.0-cfg] for Windows platforms, and is ignored on
other platforms.
- [Upgraded to LLVM 11.][73526]
- [Added tier 3\* support for the `thumbv4t-none-eabi` target.][74419]
- [Upgrade the FreeBSD toolchain to version 11.4][75204]
- [`RUST_BACKTRACE`'s output is now more compact.][75048]
\* Refer to Rust's [platform support page][forge-platform-support] for more
information on Rust's tiered platform support.
Libraries
---------
- [`CStr` now implements `Index<RangeFrom<usize>>`.][74021]
- [Traits in `std`/`core` are now implemented for arrays of any length, not just
those of length less than 33.][74060]
- [`ops::RangeFull` and `ops::Range` now implement Default.][73197]
- [`panic::Location` now implements `Copy`, `Clone`, `Eq`, `Hash`, `Ord`,
`PartialEq`, and `PartialOrd`.][73583]
Stabilized APIs
---------------
- [`Ident::new_raw`]
- [`Range::is_empty`]
- [`RangeInclusive::is_empty`]
- [`Result::as_deref`]
- [`Result::as_deref_mut`]
- [`Vec::leak`]
- [`pointer::offset_from`]
- [`f32::TAU`]
- [`f64::TAU`]
The following previously stable APIs have now been made const.
- [The `new` method for all `NonZero` integers.][73858]
- [The `checked_add`,`checked_sub`,`checked_mul`,`checked_neg`, `checked_shl`,
`checked_shr`, `saturating_add`, `saturating_sub`, and `saturating_mul`
methods for all integers.][73858]
- [The `checked_abs`, `saturating_abs`, `saturating_neg`, and `signum` for all
signed integers.][73858]
- [The `is_ascii_alphabetic`, `is_ascii_uppercase`, `is_ascii_lowercase`,
`is_ascii_alphanumeric`, `is_ascii_digit`, `is_ascii_hexdigit`,
`is_ascii_punctuation`, `is_ascii_graphic`, `is_ascii_whitespace`, and
`is_ascii_control` methods for `char` and `u8`.][73858]
Cargo
-----
- [`build-dependencies` are now built with opt-level 0 by default.][cargo/8500]
You can override this by setting the following in your `Cargo.toml`.
```toml
[profile.release.build-override]
opt-level = 3
```
- [`cargo-help` will now display man pages for commands rather just the
`--help` text.][cargo/8456]
- [`cargo-metadata` now emits a `test` field indicating if a target has
tests enabled.][cargo/8478]
- [`workspace.default-members` now respects `workspace.exclude`.][cargo/8485]
- [`cargo-publish` will now use an alternative registry by default if it's the
only registry specified in `package.publish`.][cargo/8571]
Misc
----
- [Added a help button beside Rustdoc's searchbar that explains rustdoc's
type based search.][75366]
- [Added the Ayu theme to rustdoc.][71237]
Compatibility Notes
-------------------
- [Bumped the minimum supported Emscripten version to 1.39.20.][75716]
- [Fixed a regression parsing `{} && false` in tail expressions.][74650]
- [Added changes to how proc-macros are expanded in `macro_rules!` that should
help to preserve more span information.][73084] These changes may cause
compiliation errors if your macro was unhygenic or didn't correctly handle
`Delimiter::None`.
- [Moved support for the CloudABI target to tier 3.][75568]
- [`linux-gnu` targets now require minimum kernel 2.6.32 and glibc 2.11.][74163]
Internal Only
--------
- [Improved default settings for bootstrapping in `x.py`.][73964]
You can read details about this change in the ["Changes to `x.py`
defaults"](https://blog.rust-lang.org/inside-rust/2020/08/30/changes-to-x-py-defaults.html)
post on the Inside Rust blog.
- [Added the `rustc-docs` component.][75560] This allows you to install
and read the documentation for the compiler internal APIs. (Currently only
available for `x86_64-unknown-linux-gnu`.)
