[breaking-change] for lint authors
You must now implement LateLintPass or EarlyLintPass as well as LintPass and use either register_late_lint_pass or register_early_lint_pass, rather than register_lint_pass.
There is a minor [breaking-change] for lint authors - some functions which were previously defined on `lint::Context` have moved to a trait - `LintContext`, you may need to import that trait to avoid name resolution errors.
Since enums are namespaced now, should we also remove the `Fk` prefixes from `FnKind` and remove the reexport? (The reexport must be removed because otherwise it clashes with glob imports containing `ItemFn`). IMO writing `FnKind::Method` is much clearer than `FkMethod`.
This is purposely separate to the "rust-intrinsic" ABI, because these
intrinsics are theoretically going to become stable, and should be fine
to be independent of the compiler/language internals since they're
intimately to the platform.
This commit removes all unstable and deprecated functions in the standard
library. A release was recently cut (1.3) which makes this a good time for some
spring cleaning of the deprecated functions.
Makes the lint a bit more accurate, and improves the quality of the diagnostic
messages by explicitly returning an error message.
The new lint is also a little more aggressive: specifically, it now
rejects tuples, and it recurses into function pointers.
The "hint" mechanism is essentially used as a workaround to compute
types for expressions which have not yet been type-checked. This
commit clarifies that usage, and limits the effects to the places
where it is currently necessary.
Fixes#26210.

and deprecate/remove unsigned_negation lint.
This is useful to avoid causing breaking changes in case #![deny(unknown_lints)]
is used and lint is removed.
Fixes#24249
I've tagged all items that were missing docs to allow them to compile for now, the ones in core/num should probably be documented at least.
This is also a breaking change for any crates using `#[deny(missing_docs)]` that have undocumented constants, not sure there is any way to avoid this without making it a separate lint?
This patch implements the next chunk of flattening out the type checking context. In a series of patches I moved around the necessary state and logic in order to delete the `Typer` and `ClosureTyper` traits. My next goal is to clean the interfaces and start to move the normalization code behind them.
r? @nrc I hope my PR is coherent, doing this too late at night ;)
Fixes#26646.
Loops over all `#[repr(..)]` attributes instead of stopping at the first one to make sure they are all marked as used. Previously it stopped after the first `#[repr(C)]` was found causing all other attributes to be skipped by the linter.
This commit finalizes the work of the past commits by fully moving the fulfillment context into
the InferCtxt, cleaning up related context interfaces, removing the Typer and ClosureTyper
traits and cleaning up related intefaces
