- Add patch add-option-to-allow-warnings.patch to add a config option
which allows warnings and so enables v1.38 to bootstrap itself.
- Update to version 1.38.0
+ Language
- The `#[global_allocator]` attribute can now be used in submodules.
- The `#[deprecated]` attribute can now be used on macros.
+ Compiler
- Added pipelined compilation support to `rustc`. This will
improve compilation times in some cases.
+ Libraries
- `ascii::EscapeDefault` now implements `Clone` and `Display`.
- Derive macros for prelude traits (e.g. `Clone`, `Debug`, `Hash`) are now
available at the same path as the trait. (e.g. The `Clone` derive macro
is available at `std::clone::Clone`). This also makes all built-in macros
available in `std`/`core` root. e.g. `std::include_bytes!`.
- `str::Chars` now implements `Debug`.
- `slice::{concat, connect, join}` now accepts `&[T]` in addition to `&T`.
- `*const T` and `*mut T` now implement `marker::Unpin`.
- `Arc<[T]>` and `Rc<[T]>` now implement `FromIterator<T>`.
- Added euclidean remainder and division operations (`div_euclid`,
`rem_euclid`) to all numeric primitives. Additionally `checked`,
`overflowing`, and `wrapping` versions are available for all
integer primitives.
- `thread::AccessError` now implements `Clone`, `Copy`, `Eq`, `Error`, and
`PartialEq`.
- `iter::{StepBy, Peekable, Take}` now implement `DoubleEndedIterator`.
+ Stabilized APIs
- `<*const T>::cast`
- `<*mut T>::cast`
- `Duration::as_secs_f32`
- `Duration::as_secs_f64`
- `Duration::div_f32`
- `Duration::div_f64`
- `Duration::from_secs_f32`
- `Duration::from_secs_f64`
- `Duration::mul_f32`
- `Duration::mul_f64`
- `any::type_name`
+ Cargo
- Added pipelined compilation support to `cargo`.
- You can now pass the `--features` option multiple times to enable
multiple features.
+ Misc
- `rustc` will now warn about some incorrect uses of
`mem::{uninitialized, zeroed}` that are known to cause undefined behaviour.

Subject: [PATCH] rustbuild: allow disabling deny(warnings) for bootstrap
|
|
|
|
When deny-warnings is not specified or set to true, the behaviour is the same as before.
|
|
When deny-warnings is set to false, warnings are now allowed
|
|
|
|
Fixes #63911
|
