--- Comment #4 from Martin Jambor <jamborm at gcc dot gnu.org> ---
This does not look like a duplicate of PR 111573.
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?
