Fix `suspicious_xor_used_as_pow.rs` performance
The original `suspicious_xor_used_as_pow` lint had poor performance, so I fixed that + a little refactor so that module is readable.
**107 millis. -> 106 millis.** Using `SPEEDTEST` on Rust's VMs
fix#11060
changelog: [`suspicious_xor_used_as_pow`]: Improve performance by 0.934%
New lint `ignored_unit_patterns`
This idea comes from #11238. I've put the lint in `pedantic` as it might trigger numerous positives (three in Clippy itself).
changelog: [`ignored_unit_patterns`]: new lint
Suppress `question_mark` warning if `question_mark_used` is not allowed
Closes#11283
changelog: [`question_mark`]: Don't lint if `question_mark_used` is not allowed
[`unwrap_used`]: Do not lint unwrapping on `!` or never-like enums
Fixes#11245
changelog: [`unwrap_used`]: Do not lint unwrapping on `!` or never-like enums
changelog: [`expect_used`]: Do not lint unwrapping on `!` or never-like enums
`redundant_closure` fixes
fixes#8548
A good chunk of the code is fixing false negatives. The old code banned any non late-bound regions from appearing in the callee's signature. The new version checks when the late-bound region is actually required.
changelog: Better track when a early-bound region appears when a late-bound region is required in `redundant_closure`.
changelog: Don't lint `redundant_closure` when the closure gives explicit types.
new lint: [`readonly_write_lock`]
Closes#8555
A new lint that catches `RwLock::write` calls to acquire a write lock only to read from it and not actually do any writes (mutations).
changelog: new lint: [`readonly_write_lock`]
Now `option_env_unwrap` warns even if a variable isn't set at compiletime
Fixes#10742
changelog: Fix false negative where `option_env_unwrap` wouldn't warn if the env variable isn't set at compile-time.
Currently, Clippy, Miri, Rustfmt, and rustc all use an environment variable to
indicate that output should be blessed, but they use different variable names.
In order to improve consistency, this patch applies the following changes:
- Emit `RUSTC_BLESS` within `prepare_cargo_test` so it is always
available
- Change usage of `MIRI_BLESS` in the Miri subtree to use `RUSTC_BLESS`
- Change usage of `BLESS` in the Clippy subtree to `RUSTC_BLESS`
- Change usage of `BLESS` in the Rustfmt subtree to `RUSTC_BLESS`
- Adjust the blessable test in `rustc_errors` to use this same
convention
- Update documentation where applicable
Any tools that uses `RUSTC_BLESS` should check that it is set to any value
other than `"0"`.
Split some functions with many arguments into builder pattern functions
r? `@estebank`
This doesn't resolve all of the ones in rustc, mostly because I need to do other cleanups in order to be able to use some builder derives from crates.io
Works around https://github.com/rust-lang/rust/issues/90672 by making `x test rustfmt --bless` format itself instead of testing that it is formatted
Fix integration tests #2
fix integration tests.
It turned out that the following tests fail to build at all:
chalk, combine, stdarch and hyper.
This is often a problem of passing `--all-targets --all-features`, in case of combine though, outdated deps were to blame.
I have opened tickets against combine and rustfmt
https://github.com/rust-lang/rustfmt/issues/5859https://github.com/Marwes/combine/issues/357
should we just remove the other failing repos? :/

Add *no merge policy* note via rustbot
I just found out that ``@rustbot`` can automatically add a note about our *no-merge commits* policy, if it detects a merge commit: https://forge.rust-lang.org/triagebot/no-merge.html
Funnly enough, I found this while writing documentation for Marker. ``@rustbot`` is a cool tool 👍
