Debug info is something I haven't really thought about. That's probably something that should have its own test case.
These are aspiring to show that the call frame is correct for the given architecture - variables are at the right offset and so forth - other things like metadata / attribute propagation are target independent and should have their own tests.
I'll look at removing the attributes from these, would give better signal to noise.
