Suggest importing for partial mod path matching in name resolving Fixes #112590
…pastorino Make RPITITs assume/require their parent method's predicates Removes a FIXME from the `param_env` query where we were manually adding the parent function's predicates to the RPITIT's assumptions. r? `@spastorino`
Add simple markdown formatting to `rustc --explain` output This is a second attempt at #104540, which is #63128 without dependencies. This PR adds basic markdown formatting to `rustc --explain` output when available. Currently, the output just displays raw markdown: this works of course, but it really doesn't look very elegant. (output is `rustc --explain E0038`) <img width="583" alt="image" src="https://github.com/rust-lang/rust/assets/13724985/ea418117-47af-455b-83c0-6fc59276efee"> After this patch, sample output from the same file: <img width="693" alt="image" src="https://github.com/rust-lang/rust/assets/13724985/12f7bf9b-a3fe-4104-b74b-c3e5227f3de9"> This also obeys the `--color always/auto/never` command option. Behavior: - If pager is available and supports color, print with formatting to the pager - If pager is not available or fails print with formatting to stdout - otherwise without formatting - Follow `--color always/never` if suppied - If everything fails, just print plain text to stdout r? `@oli-obk` cc `@estebank` (since the two of you were involved in the previous discussion)
Return `Ok` on kill if process has already exited This will require an FCP from `@rust-lang/libs-api.` Fixes #112423. See that issue for more details.
Move `TyCtxt::mk_x` to `Ty::new_x` where applicable Part of rust-lang/compiler-team#616 turns out there's a lot of places we construct `Ty` this is a ridiculously huge PR :S r? `@oli-obk`
…indows-fix, r=pietroalbini Fix the tests-listing-format-json test on Windows tests/ui/test-attrs/tests-listing-json-format.rs was failing on Windows because each path in the json-formatted output contained "\\\\" instead of "\\". `runtest::TestCx::normalize_output` already checks the compile flags for json-related arguments to handle this case, so I added an equivalent check for the new run flag.
…lbini fix compiletest crash ### Motivation When running compiler-tests locally for the `wasm32` platform, one test repeatedly crashed. It does not crash on the CI, only locally. Investigation shows that the `compiletest` itself crashes > panicked-at-attempt-to-subtract-with-overflow ```rust let mut head = replace(bytes, Vec::new()); let mut middle = head.split_off(HEAD_LEN); // The following line will panic let tail = middle.split_off(middle.len() - TAIL_LEN).into_boxed_slice(); let skipped = new_len - HEAD_LEN - TAIL_LEN; ``` ### Background The code in question collects the output of a process. Small output is kept completely, but larger output is kept only partially: the first 160 kB and the last 256 kB. The code that performs this split crashes if the data size is less than 416 kB. There is an early out based on the "filtered" length, but it is possible that the filtered length is greater than the real length. It seems that this code was written with the assumption that the filtered length is larger than the real length, which is not true in general. When running CI tests locally using `src/ci/docker/run.sh`, the filtered folder is `/checkout`, which is shorter than the placeholder length of 32 bytes. ### Note This PR should not change any behaviour. It only adds an early our for a case which will definitely crash (at least if compiletest is build with integer checks). Note that an early out makes sense here: If the real data is too small, it does not sense to split it.

Use `llvm-config` instead of `download-ci-llvm` in PGO script This should avoid CI breakage when the LLVM stamp is updated, and also it will avoid an unnecessary LLVM download from CI. r? `@jyn514`
CI: merge x86_64-gnu-llvm-14 and x86_64-gnu-llvm-14-stage1 CI jobs Another attempt to shorten CI job times. Suggested by `@the8472` [here](https://rust-lang.zulipchat.com/#narrow/stream/242791-t-infra/topic/CI.20usage/near/367172221).
Update compiler builtins cc rust-lang/compiler-builtins#532 (comment) in particular this pulls in rust-lang/compiler-builtins#532 and rust-lang/compiler-builtins#535. Fixes rust-lang/rust#93166. Fixes rust-lang/git2-rs#706. Fixes rust-lang/rust#109064. Fixes rust-lang/wg-cargo-std-aware#74.
CI: merge msvc cargo and tools jobs The `x86_64-msvc-cargo` and `x86_64-msvc-tools` jobs both run for ~1 hour, but most of that time is actually spent in building LLVM and `rustc`, so I want to try merging them. 
Update LLVM submodule This adds rust-lang/llvm-project#147.
