There was a problem hiding this comment.
This is passing misleading input into compile_test via should_run, I'm not sure if we should try to reuse run_pass_test across run and not-run modes like this. At minimum coupling run into should_run probably is necessary.

Apologies for the delay in reviewing @lukas-code, unless labels are updated I at least don't see PRs. @rustbot author |

If you have crate A with a dependency on crate B, and crate B with a dev-dependency on A, then you might see "mismatched types" errors on types that seem to be equal. This PR adds a note that explains that the types are different, because crate B is compiled twice, one time with
cfg(test)and one time without.I haven't found a good way to create circular dependencies in UI tests, so I abused the incremental tests instead. As a bonus, incremental tests support "cpass" now.
