Thanks, I came to this PR after seeing failures across the RISC-V bots. I think `%check_clang_tidy` may be problematic for this test due to the line endings juggling. But by my understanding the key thing check_clang_tidy does for the issue some of us are seeing on the bots is to append `--` to the invocation so that clang-tidy won't search parent directories for a compilation database.
