Warn if `dsymutil` returns an error code This checks the error code returned by `dsymutil` and warns if it failed. It also provides the stdout and stderr logs from `dsymutil`, similar to the native linker step. I tried to think of ways to test this change, but so far I haven't found a good way, as you'd likely need to inject some nonsensical args into `dsymutil` to induce failure, which feels too artificial to me. Also, https://github.com/rust-lang/rust/issues/79361 suggests Rust is on the verge of disabling `dsymutil` by default, so perhaps it's okay for this change to be untested. In any case, I'm happy to add a test if someone sees a good approach. Fixes https://github.com/rust-lang/rust/issues/78770 |
