--- Comment #4 from Andrew Pinski ---
The testcase in comment #0 started to be vectorized in GCC 13
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=18437
--- Comment #9 from Andrew Pinski ---
For the original testcase in comment #0, with `-O3 -fno-vect-cost-model` GCC
can vectorize it on aarch64 but not on x86_64.
