--- Comment #4 from Victor Do Nascimento <victorldn at gcc dot gnu.org> ---
I've been able to confirm the offending function and the responsible loop are
the same in x86_64 and AArch64, so I've created a ticket with the reduced
testcase and will use that to track the change to the cost model.

Marking this bug as a duplicate of that one.
