2020-09-20Update Clippy testcasesChristiaan Dirkx-65/+91
Update the test `redundant_pattern_matching`: check if `is_some` and `is_none` are suggested within const contexts.
2020-09-20Auto merge of #76136 - CDirkx:const-result, r=dtolnaybors-183/+93
Stabilize some Result methods as const Stabilize the following methods of Result as const: - `is_ok` - `is_err` - `as_ref` A test is also included, analogous to the test for `const_option`. These methods are currently const under the unstable feature `const_result` (tracking issue: #67520). I believe these methods to be eligible for stabilization because of the stabilization of #49146 (Allow if and match in constants) and the trivial implementations, see also: [PR#75463](https://github.com/rust-lang/rust/pull/75463) and [PR#76135](https://github.com/rust-lang/rust/pull/76135). Note: these methods are the only methods currently under the `const_result` feature, thus this PR results in the removal of the feature. Related: #76225
2020-09-20Update Clippy testcasesChristiaan Dirkx-183/+93
Update the test `redundant_pattern_matching`: check if `is_ok` and `is_err` are suggested within const contexts. Also removes the `redundant_pattern_matching_const_result` test, as it is no longer needed.

2020-09-08Adjust Clippy for CONST_ITEM_MUTATION lintAaron Hill-45/+23
We no longer lint assignments to const item fields in the `temporary_assignment` lint, since this is now covered by the `CONST_ITEM_MUTATION` lint. Additionally, we `#![allow(const_item_mutation)]` in the `borrow_interior_mutable_const.rs` test. Clippy UI tests are run with `-D warnings`, which seems to cause builtin lints to prevent Clippy lints from running.
2020-09-02Improve recovery on malformed format callSasha-3/+3
If a comma in a format call is replaced with a similar token, then we emit an error and continue parsing, instead of stopping at this point.

2020-08-11Rollup merge of #75098 - Ryan1729:clippy-pointer-cast-lint-experiment, r=oli-obkDylan DPC-0/+236
Clippy pointer cast lint experiment This PR is an experiment about exposing more parts of `rustc_typeck` for use in `clippy`. In particular, the code that checks where a cast is valid or not was exposed, which necessitated exposing [`FnCtxt`](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_typeck/check/struct.FnCtxt.html), and figuring out how to create an instance of that type inside `clippy`. This was prompted by [this clippy issue](https://github.com/rust-lang/rust-clippy/issues/2064). r? @oli-obk

2020-08-07Auto merge of #74821 - oli-obk:const_eval_read_uninit_fast_path, r=wesleywiserbors-21/+1
Check whether locals are too large instead of whether accesses into them are too large Essentially this stops const prop from attempting to optimize ```rust let mut x = [0_u8; 5000]; x[42] = 3; ``` I don't expect this to be a perf improvement without #73656 (which is also where the lack of this PR will be a perf regression). r? @wesleywiser

2020-07-29Update clippy ui test.Oliver Scherer-21/+1
The reason we do not trigger these lints anymore is that clippy sets the mir-opt-level to 0, and the recent changes subtly changed how the const propagator works.

2020-06-22Stop using old version of `syn` in `rustc-workspace-hack`Aaron Hill-1/+3
None of the tools seem to need syn 0.15.35, so we can just build syn 1.0. This was causing an issue with clippy's `compile-test` program: since multiple versions of `syn` would exist in the build directory, we would non-deterministically pick one based on filesystem iteration order. If the pre-1.0 version of `syn` was picked, a strange build error would occur (see https://github.com/rust-lang/rust/pull/73594#issuecomment-647671463) To prevent this kind of issue from happening again, we now panic if we find multiple versions of a crate in the build directly, instead of silently picking the first version we find.
