"only-" header not supported

[RalfJung]

We added a only-linux test to our test suite and were very confused to see it run on macOS as well.

Inspecting the compiletest-rs code, it looks like only has not been synced over from rustc? That would mean this crate is 30 months outdated.

I think with the current compiletest-rs you can only use the ignore header, so that would be something like

// ignore-macos
// ignore-windows

depending on your needs.

Yeah that's what we went with for now. Thanks.
