This test makes sure that functions marked as artificial in metadata are reported that way.  It's been a while, but my recollection is I started with IR generated by clang, ran it through llvm-reduce, and then further reduced it by hand.

What are you objecting to?  Do you want the test function to look more like an artificial function in some way?  Do you want artificial functions not to be called out by kernel-info?
