…are resolved Also mark derive helpers as known as a part of the derive container's expansion instead of expansion of the derives themselves which may happen too late.
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 rust-lang#63911 Signed-off-by: Marc-Antoine Perennou <Marc-Antoine@Perennou.com>
resolve: Block expansion of a derive container until all its derives are resolved So, it turns out there's one more reason to block expansion of a `#[derive]` container until all the derives inside it are resolved, beside `Copy` (rust-lang#63248). The set of derive helper attributes registered by derives in the container also has to be known before the derives themselves are expanded, otherwise it may be too late (see rust-lang#63468 (comment) and the `#[stable_hasher]`-related test failures in rust-lang#63468). So, we stop our attempts to unblock the container earlier, as soon as the `Copy` status is known, and just block until all its derives are resolved. After all the derives are resolved we immediately go and process their helper attributes in the item, without delaying it until expansion of the individual derives.

Validation: check raw wide pointer metadata While I was at it, I also added a missing check for slices not to be too big. r? @oli-obk Fixes rust-lang/miri#918
ty: use Align for ReprOptions pack and align.
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 rust-lang#63911
…imulacrum Fix build src/libtest Fixes rust-lang#63928 r? @Mark-Simulacrum
…Simulacrum Update rust-installer to limit memory use See rust-lang/rust-installer#98 -- on a many-core machine, the xz memory for so many threads is more than a 32-bit process can handle. The xz stream is now limited to 8 threads. r? @alexcrichton
