My main concern would be that significantly automatically reduced LLVM
debug info IR metadata might produce "strange" examples (valid
according to the verifier, but so quirky as to be hard to know if
they're meant to be supported or if we should/might eventually deem
them invalid according to the verifier) that may be hard to
understand, while still not being short enough to be hand craftable -
in which case I'm not sure how much of an improvement to the current
situation they would be.
So I think at least for the first few examples of automatically (or
even significantly hand reduced) test cases with debug info metadata
we'll want to look pretty carefully at them to discuss whether they
improve or harm test case maintainability.
