# This job appears to be checking two separate things:
# - That we can build the compiler with `--enable-debug`
#   (without necessarily testing the result).
# - That the tests with `//@ needs-force-clang-based-tests` pass, since they
#   don't run by default unless RUSTBUILD_FORCE_CLANG_BASED_TESTS is set.
#   - FIXME(https://github.com/rust-lang/rust/pull/126155#issuecomment-2156314273):
#     Currently we only run the subset of tests with "clang" in their name.
#   - See also FIXME(#132034)
