2023-09-28Auto merge of #116199 - Urgau:simplify-invalid_ref_casting, r=cjgillotbors-1/+1
Simplify some of the logic in the `invalid_reference_casting` lint This PR simplifies 2 areas of the logic for the `invalid_reference_casting` lint: - The init detection: we now use the newly added `expr_or_init` function instead of a manual detection - The ref-to-mut-ptr casting detection logic: I simplified this logic by caring less hardly about the order of the casting operations Those two simplifications permits us to detect more cases, as can be seen in the test output changes.

A cosmetic change, so the callsite doesn't have to import things

2023-08-04Auto merge of #114414 - cjgillot:early-unnameable-test, r=petrochenkovbors-2/+0
Make test harness lint about unnnameable tests. Implementation of https://github.com/rust-lang/rust/pull/113734#discussion_r1283073418 About the options suggested in https://github.com/rust-lang/rust/issues/36629#issuecomment-404753945: adding this case to unused_attribute was just more complicated. I'll try to understand a bit more what you had in mind in https://github.com/rust-lang/rfcs/pull/2471#issuecomment-397241123 This was just simpler to do in a standalone PR. I'll remove the corresponding changes from https://github.com/rust-lang/rust/pull/113734 later. r? `@petrochenkov`
2023-08-03Auto merge of #108955 - Nilstrieb:dont-use-me-pls, r=oli-obkbors-1/+2
Add `internal_features` lint Implements https://github.com/rust-lang/compiler-team/issues/596 Also requires some more test blessing for codegen tests etc `@jyn514` had the idea of just `allow`ing the lint by default in the test suite. I'm not sure whether this is a good idea, but it's definitely one worth considering. Additional input encouraged.
2023-08-03Rollup merge of #113657 - Urgau:expand-incorrect_fn_null_check-lint, r=cjgillotMatthias Krüger-3/+3
Expand, rename and improve `incorrect_fn_null_checks` lint This PR, - firstly, expand the lint by now linting on references - secondly, it renames the lint `incorrect_fn_null_checks` -> `useless_ptr_null_checks` - and thirdly it improves the lint by catching `ptr::from_mut`, `ptr::from_ref`, as well as `<*mut _>::cast` and `<*const _>::cast_mut` Fixes https://github.com/rust-lang/rust/issues/113601 cc ```@est31```
2023-08-03Make test harness lint about unnnameable tests.Camille GILLOT-2/+0
2023-08-03Add `internal_features` lintNilstrieb-1/+2
It lints against features that are inteded to be internal to the compiler and standard library. Implements MCP #596. We allow `internal_features` in the standard library and compiler as those use many features and this _is_ the standard library from the "internal to the compiler and standard library" after all. Marking some features as internal wasn't exactly the most scientific approach, I just marked some mostly obvious features. While there is a categorization in the macro, it's not very well upheld (should probably be fixed in another PR). We always pass `-Ainternal_features` in the testsuite About 400 UI tests and several other tests use internal features. Instead of throwing the attribute on each one, just always allow them. There's nothing wrong with testing internal features^^

2023-04-18Add `rustc_fluent_macro` to decouple fluent from `rustc_macros`Nilstrieb-1/+1
Fluent, with all the icu4x it brings in, takes quite some time to compile. `fluent_messages!` is only needed in further downstream rustc crates, but is blocking more upstream crates like `rustc_index`. By splitting it out, we allow `rustc_macros` to be compiled earlier, which speeds up `x check compiler` by about 5 seconds (and even more after the needless dependency on `serde_json` is removed from `rustc_data_structures`).

2023-02-22errors: generate typed identifiers in each crateDavid Wood-0/+4
Instead of loading the Fluent resources for every crate in `rustc_error_messages`, each crate generates typed identifiers for its own diagnostics and creates a static which are pulled together in the `rustc_driver` crate and provided to the diagnostic emitter.

2022-12-28Rollup merge of #105484 - nbdd0121:upcast, r=compiler-errorsfee1-dead-0/+3
Implement allow-by-default `multiple_supertrait_upcastable` lint The lint detects when an object-safe trait has multiple supertraits. Enabled in libcore and liballoc as they are low-level enough that many embedded programs will use them. r? `@nikomatsakis`

2022-12-12Reinstate `{Early,Late}LintPassObjects`.Nicholas Nethercote-6/+0
I removed these in #105291, and subsequently learned they are necessary for performance. This commit reinstates them with the new and more descriptive names `RuntimeCombined{Early,Late}LintPass`, similar to the existing passes like `BuiltinCombinedEarlyLintPass`. It also adds some comments, particularly emphasising how we have ways to combine passes at both compile-time and runtime. And it moves some comments around.
