Need to update those rmake tests to reflect nightly build-dir layout changes.

The run-make-support library was changed

Mind reviewing 86a4c65 is good?

⚠️ Warning ⚠️

Some commits in this PR modify submodules.

If this was not intentional, see I changed a submodule on accident in the rustc dev guide.

+    });
+    assert_eq!(rlibs.len(), 1, "expected exactly one compiler_builtins rlib: {rlibs:?}");


length assertion should guard us well to only get the one and only artifact.

Or @jieyouxu if you are willing to take a look at the rmake change? 🥺

-        .unwrap();
+    // The rlib file is emitted as an intermediate build artifacts.
+    // Do not hardcode the path.
+    let mut rlibs = recursive_find_files(&target_dir, |path| {


should we change this to target_dir.join("debug")?
If it's built in release mode we could end up finding the debug and release .rlibs and hit the assert below.
Not sure if that is applicable for run-make tests

Good point. Updated.

Cargo enables build-dir layout v2 by default on nightly (rust-lang/cargo PR 17258). Intermediate build artifacts no longer live in `<target-dir>/<triple>/<profile>/deps/` but in per-unit `build/<pkg>/<hash>/out/` directories.

`xsv` locates binaries relative to `current_exe()`, which assumes Cargo's legacy build-dir layout: https://triage.rust-lang.org/gha-logs/rust-lang/rust/90658568103 We should revisit and replace xsv to something else with similar portfolio

Finished benchmarking commit (83709ee): comparison URL.

Overall result: ❌✅ regressions and improvements - please read:

Our benchmarks found a performance regression caused by this PR.
This might be an actual regression, but it can also be just noise.

Next Steps:

If the regression was expected or you think it can be justified,
please write a comment with sufficient written justification, and add
@rustbot label: +perf-regression-triaged to it, to mark the regression as triaged.
If you think that you know of a way to resolve the regression, try to create
a new PR with a fix for the regression.
If you do not understand the regression or you think that it is just noise,
you can ask the @rust-lang/wg-compiler-performance working group for help (members of this group
were already notified of this PR).

The big regression on large-workspace was expected, and comes from Cargo passing in many more -L flags to rustc, which is not optimized for something like this at the moment. In absolute wall-time numbers, it was a regression of a few milliseconds on a crate with a thousand transitive dependencies, so it shouldn't be such a big deal in practice.

#158823 should improve the performance here considerably.
