2023-09-12Auto merge of #115699 - RalfJung:interpret-abi-compat, r=oli-obkbors-29/+60
interpret: change ABI-compat test to be type-based This makes the test consistent across targets. Otherwise the chances are very high that ABI mismatches get accepted on x86_64 but still fail on many other targets with more complicated ABIs. This implements (most of) the rules described in https://github.com/rust-lang/rust/pull/115476.

``` $ ls /bin/bash ls: cannot access '/bin/bash': No such file or directory ``` On certain systems, `/bin` and `/usr/bin` are nothing but wastelands, with just `env`around as the last survivor of the great purge. The binaries have cowardly hidden away and only `env` can show us the way to greatness (bash). ❄️
2023-09-08Auto merge of #115418 - Zoxc:freeze-source, r=oli-obkbors-47/+39
Use `Freeze` for `SourceFile` This uses the `Freeze` type in `SourceFile` to let accessing `external_src` and `lines` be lock-free. Behavior of `add_external_src` is changed to set `ExternalSourceKind::AbsentErr` on a hash mismatch which matches the documentation. `ExternalSourceKind::Unneeded` was removed as it's unused. Based on https://github.com/rust-lang/rust/pull/115401.

2023-09-05Auto merge of #114843 - Zalathar:test-coverage-map, r=oli-obkbors-5/+614
coverage: Explicitly test the coverage maps produced by codegen/LLVM Our existing coverage tests verify the output of end-to-end coverage reports, but we don't have any way to test the specific mapping information (code regions and their associated counters) that are emitted by `rustc_codegen_llvm` and LLVM. That makes it harder to to be confident in changes that would modify those mappings (whether deliberately or accidentally). This PR addresses that by adding a new `coverage-map` test suite that does the following: - Compiles test files to LLVM IR assembly (`.ll`) - Feeds those IR files to a custom tool (`src/tools/coverage-dump`) that extracts and decodes coverage mappings, and prints them in a more human-readable format - Checks the output of that tool against known-good snapshots --- I recommend excluding the last commit while reviewing the main changes, because that last commit is just ~40 test files copied over from `tests/run-coverage`, plus their blessed coverage-map snapshots and a readme file. Those snapshots aren't really intended to be checked by hand; they're mostly there to increase the chances that an unintended change to coverage maps will be observable (even if it requires relatively specific circumstances to manifest).

2023-09-05Auto merge of #115543 - Kobzol:opt-dist-retry-download, r=Mark-Simulacrumbors-1/+30
Retry download of rustc-perf in opt-dist This should help resolving spurious network errors. It also increases the timeout for the archive download. r? `@Mark-Simulacrum`
2023-09-05Add test suite `coverage-map` to test coverage mappings emitted by LLVMZalathar-5/+74
We compile each test file to LLVM IR assembly, and then pass that IR to a dedicated program that can decode LLVM coverage maps and print them in a more human-readable format. We can then check that output against known-good snapshots. This test suite has some advantages over the existing `run-coverage` tests: - We can test coverage instrumentation without needing to run target binaries. - We can observe subtle improvements/regressions in the underlying coverage mappings that don't make a visible difference to coverage reports.

2023-09-04Auto merge of #114089 - Urgau:allow-with-implied-by, r=petrochenkovbors-0/+838
Add an allow attribute suggestion along with the implied by suggestion This PR adds an `#[allow(...)]` attribute hep suggestion along with the implied by suggestion: ```diff note: `-W dead-code` implied by `-W unused` + help: to override `-W unused` add `#[allow(dead_code)]` ``` This PR also adds the `OnceHelp` lint level (similar to `OnceNote`) to only put the help message one time, like the implied note.
