/*! Tests interrupt ABIs have a constricted signature
2+
3+
Most interrupt ABIs share a similar restriction in terms of not allowing most signatures.
4+
Specifically, they generally cannot have arguments or return types.
5+
So we test that they error in essentially all of the same places.
6+
A notable and interesting exception is x86.
7+
8+
This test uses `cfg` because it is not testing whether these ABIs work on the platform.
