Wild already behaves correctly when a hidden symbol can only be resolved from a shared library (DSO) it errors with an undefined symbol. I confirmed that GNU ld and mold behave the same way. However, Wild didn’t have an integration test for this error case.
This PR adds a new test hidden-undef.c to verify that linking fails when a hidden symbol is declared in the main object but only defined in a shared library.
It also moves hidden-undef.sh from the misc group to ignore in mold_skip_tests.toml, since Wild’s behaviour is correct but the error message format differs from mold’s.
