There are times where computing a value may be cheap, or where computing a reference may be expensive, so this fills out the possibilities.
…ref_of}` While the `provide_*` methods already short-circuit when a value has been provided, there are times where an expensive computation is needed to determine if the `provide_*` method can even be called.
Before, the MIR validator used RevealAll in its ParamEnv for type checking. This could cause false negatives in some cases due to RevealAll ParamEnvs not always use all predicates as expected here. Since some MIR passes like inlining use RevealAll as well, keep using it in the MIR validator too, but when it fails usign RevealAll, also try the check without it, to stop false negatives.
Before, it called `normalize_erasing_regions` twice since `equal_up_to_regions` called it as well for both types.
`std::os::fd` defines types like `OwnedFd` and `RawFd` and is common between Unix and non-Unix platforms that share a basic file-descriptor concept. Rust currently uses this internally to simplify its own code, but it would be useful for external users in the same way, so make it public. This means that `OwnedFd` etc. will all appear in three places, for example on unix platforms: - `std::os::fd::OwnedFd` - `std::os::unix::io::OwnedFd` - `std::os::unix::prelude::OwnedFd`
Add `#[unstable(feature = "os_fd", issue = "98699")]` to the new `pub use` declarations.
Walkthrough currently say: ``` rustup target add aarch_64-fuchsia ``` but should say ``` rustup target add aarch64-fuchsia ```
The impl-items list stopped being nested inside a docblock since c1b1d68

Add additional methods to the Demand type This adds on to the original tracking issue rust-lang#96024 r? ````@yaahc````
… r=oli-obk Try normalizing types without RevealAll in ParamEnv in MIR validation Before, the MIR validator used RevealAll in its ParamEnv for type checking. This could cause false negatives in some cases due to RevealAll ParamEnvs not always use all predicates as expected here. Since some MIR passes like inlining use RevealAll as well, keep using it in the MIR validator too, but when it fails usign RevealAll, also try the check without it, to stop false negatives. Fixes rust-lang#99866 cc ```@compiler-errors``` who nicely helped me on zulip
…imulacrum Change implementation of `-Z gcc-ld` and `lld-wrapper` again This PR partially reverts rust-lang#97375 and uses the strategy described in rust-lang#97402 (comment) instead, thus fixes rust-lang#97755.
…henkov Add warning against unexpected --cfg with --check-cfg This PR adds a warning when an unexpected `--cfg` is specified but not in the specified list of `--check-cfg`. This is the follow-up PR I mentioned in rust-lang#99519. r? ````@petrochenkov````
…re-whitespace, r=notriddle Remove unneeded where whitespace It fixes these two bugs:   It's a relic from a very old time (this commit: rust-lang@bfd01b7). You can test the result [here](https://rustdoc.crud.net/imperio/remove-unneeded-where-whitespace/lib2/struct.WhereWhitespace.html). cc ````@jsha```` r? ````@notriddle````

…re-css, r=jsha rustdoc: remove unused `.docblock .impl-items` CSS The impl-items list stopped being nested inside a docblock since c1b1d68
