2022-08-15Revert let_chains stabilizationNilstrieb-1/+1
This reverts commit 326646074940222d602f3683d0559088690830f4. It was discovered that they are not implemented correctly, which does not make them ready for stabilization.
2022-07-27lint: add bad opt access internal lintDavid Wood-0/+6
Some command-line options accessible through `sess.opts` are best accessed through wrapper functions on `Session`, `TyCtxt` or otherwise, rather than through field access on the option struct in the `Session`. Adds a new lint which triggers on those options that should be accessed through a wrapper function so that this is prohibited. Options are annotated with a new attribute `rustc_lint_opt_deny_field_access` which can specify the error message (i.e. "use this other function instead") to be emitted. A simpler alternative would be to simply rename the options in the option type so that it is clear they should not be used, however this doesn't prevent uses, just discourages them. Another alternative would be to make the option fields private, and adding accessor functions on the option types, however the wrapper functions sometimes rely on additional state from `Session` or `TyCtxt` which wouldn't be available in an function on the option type, so the accessor would simply make the field available and its use would be discouraged too.

2022-07-19Auto merge of #98180 - notriddle:notriddle/rustdoc-fn, ↵bors-2/+2
r=petrochenkov,GuillaumeGomez Improve the function pointer docs This is #97842 but for function pointers instead of tuples. The concept is basically the same. * Reduce duplicate impls; show `fn (T₁, T₂, …, Tₙ)` and include a sentence saying that there exists up to twelve of them. * Show `Copy` and `Clone`. * Show auto traits like `Send` and `Sync`, and blanket impls like `Any`. https://notriddle.com/notriddle-rustdoc-test/std/primitive.fn.html
2022-07-18Update invalid atomic ordering lintTomasz Miąsko-5/+0
The restriction that success ordering must be at least as strong as its failure ordering in compare-exchange operations was lifted in #98383.
2022-07-17rustdoc: extend `#[doc(tuple_variadic)]` to fn pointersMichael Howell-2/+2
The attribute is also renamed `fake_variadic`.

Migrate half of the `rustc_passes::check_attr` diagnostics to using diagnostic derives and being translatable.
2022-07-15errors: lint on `LintDiagnosticBuilder::build`David Wood-0/+9
Apply the `#[rustc_lint_diagnostics]` attribute to `LintDiagnosticBuilder::build` so that diagnostic migration lints will trigger for it. Signed-off-by: David Wood <david.wood@huawei.com>
