pattern_analysis: add option to get a full set of witnesses

2025-07-20T16:27:30+00:00

Use `-Wunused_crate_dependencies` for compiler crates.

2025-03-19T21:59:43+00:00

It's very useful. There are some false positives involving integration tests in `rustc_pattern_analysis` and `rustc_serialize`. There is also a false positive involving `rustc_driver_impl`'s `rustc_randomized_layouts` feature. And I removed a `rustc_span` mention in a doc comment in `rustc_log` because it wasn't integral to the comment but caused a dev-dependency.

Add `pattern_complexity_limit` to `Limits`.

2025-02-16T22:30:33+00:00

It's similar to the other limits, e.g. obtained via `get_limit`. So it makes sense to handle it consistently with the other limits. We now use `Limit`/`usize` in most places instead of `Option`, so we use `Limit::new(usize::MAX)`/`usize::MAX` to emulate how `None` used to work. The commit also adds `Limit::unlimited`.

Reformat using the new identifier sorting from rustfmt

Reformat `use` declarations.

2024-07-28T22:26:52+00:00

The previous commit updated `rustfmt.toml` appropriately. This commit is the outcome of running `x fmt --all` with the new formatting options.

Add some tests

2024-07-24T06:02:55+00:00

Add blank lines after module-level `//!` comments.

2024-06-19T23:23:20+00:00

Most modules have such a blank line, but some don't. Inserting the blank line makes it clearer that the `//!` comments are describing the entire module, rather than the `use` declaration(s) that immediately follows.

Add a crate-custom test harness
