add `#[rustc_pass_by_value]` to more types
the only interesting changes here should be to `TransitiveRelation`, but I believe to be highly unlikely that we will ever use a non `Copy` type with this type.

Add miri to the well known conditional compilation names and values
This pull request adds `miri` to the list of well known names and values of the conditional compilation checking (`--check-cfg`).
This was brought up in [Zulip](https://rust-lang.zulipchat.com/#narrow/stream/246057-t-cargo/topic/RFC.203013.3A.20Checking.20conditional.20compilation.20at.20compile.20time/near/274513827) when discussing about the future of `--check-cfg`.

Warn users about `||` in let chain expressions
Or more specifically, warn that `||` operators are forbidden.
This PR is simple so I guess anyone can review 🤷

To make this work, the `#[rustc_on_unimplemented]` data needs to be used to
report method resolution errors, which is most of what this commit does.

Do not allow `#[rustc_legacy_const_generics]` on methods
It caused an ICE since `item` was `None`.
Fixes #94629.

Fixes 5167
When ``a.rs`` and ``a/mod.rs`` are both present we would emit an error
message telling the user that the module couldn't be found. However,
this behavior is misleading because we're dealing with an ambiguous
module path, not a "file not found" error.
Is the file ``a.rs`` or is it ``a/mod.rs``? Rustfmt can't decide, and
the user needs to resolve this ambiguity themselves.
Now, the error message displayed to the user is in line with what they
would see if they went to compile their code with these conflicting
module names.

Use impl substs in `#[rustc_on_unimplemented]`
We were using the trait-ref substs instead of impl substs in `rustc_on_unimplemented`, even when computing the `rustc_on_unimplemented` attached to an impl block. Let's not do that.
This PR also untangles impl and trait def-ids in the logic in `on_unimplemented` a bit.
Fixes #94675

This also affects the `non_exhaustive_omitted_patterns` and
`must_not_suspend` lints as they are not stable. This also changes the
diagnostic level to pull from `unknown_lints` instead of always being
allow or deny.
|
|
This change causes unstable lints to be ignored if the `unknown_lints`
lint is allowed. To achieve this, it also changes lints to apply as soon
as they are processed. Previously, lints in the same set were processed
as a batch and then all simultaneously applied.

Move some more bootstrap logic from python to rust
Same rationale as https://github.com/rust-lang/rust/pull/76544; it would be nice to make python entirely optional at some point.
This also removes $ROOT as an option for the build directory; I haven't been using it, and like Alex
said in https://github.com/rust-lang/rust/pull/76544#discussion_r488248930 it seems like a misfeature.
This allows running `cargo run` from src/bootstrap, although that still gives
lots of compile errors if you don't use the beta toolchain. It's not exactly the same as using `x.py`, since it won't have `BOOTSTRAP_DOWNLOAD_RUSTC` set, but it's pretty close. Doing this from the top-level directory requires https://github.com/rust-lang/cargo/issues/7290 to be fixed, or using `cargo run -p bootstrap`.
The next steps for making python optional are to move download-ci-llvm and download-rustc support into rustbuild, likely be shelling out as the python scripts do today.
It would also be nice (although not required) to move submodule support there, but that would require taking bootstrap out of the workspace to avoid errors from crates that haven't been cloned yet.

Generalize `get_nullable_type` to allow types where null is all-ones.
Generalize get_nullable_type to accept types that have an all-ones bit
pattern as their sentry "null" value.
This will allow [`OwnedFd`], [`BorrowedFd`], [`OwnedSocket`], and
[`BorrowedSocket`] to be marked with
`#[rustc_nonnull_optimization_guaranteed]`, which will allow
`Option<OwnedFd>`, `Option<BorrowedFd>`, `Option<OwnedSocket>`, and
`Option<BorrowedSocket>` to be used in FFI declarations, as described
in the [I/O safety RFC].
For example, it will allow a function like `open` on Unix and `WSASocketW`
on Windows to be declared using `Option<OwnedFd>` and `Option<OwnedSocket>`
return types, respectively.
The actual change to add `#[rustc_nonnull_optimization_guaranteed]`
to the abovementioned types will be a separate PR, as it'll depend on
having this patch in the stage0 compiler.
Also, update the diagnostics to mention that "niche optimizations" are
used in libstd as well as libcore, as `rustc_layout_scalar_valid_range_start`
and `rustc_layout_scalar_valid_range_end` are already in use in libstd.

Emit `unused_attributes` if a level attr only has a reason
Fixes a comment from `compiler/rustc_lint/src/levels.rs`. Lint level attributes that only contain a reason will also trigger the `unused_attribute` lint. The lint now also checks for the `expect` lint level.
That's it, have a great rest of the day for everyone reasoning this :upside_down_face:
