Nevertheless, it is not quite obvious what to do here. Inlining happens before unrolling and I am not sure we'd consider unrolling in early optimizations. And without unrolling, the load from the array is not easy to fold. In this testcase all (well, both) functions referenced from the array are semantically equivalent which is recognized by ICF but making it be able to pass this information to the inliner would be non-trivial... and is this the common case worth optimizing for?
