https://rustc-dev-guide.rust-lang.org/tests/running.html#running-tests-manually explains how to run the tests manually. However, it does not explain how to do this for check-pass and build-pass tests. I assume for build-pass it might just be a regular rustc invocation, but how do I check-pass tests by hand? That would be quite good to know when evaluating whether check-pass is sufficient to reproduce a problem.
