--- Comment #20 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
On zen4 hardware I now get

GCC13 with -O3 -flto -march=native -fopenmp
        2163
        2161
        2153

    Average: 2159 Iterations Per Minute

clang 17 with -O3 -flto -march=native -fopenmp
        2004
        1988
        1991

    Average: 1994 Iterations Per Minute

trunk -O3 -flto -march=native -fopenmp
    Operation: Resizing:
        2126
        2135
        2123

    Average: 2128 Iterations Per Minute

So no big changes here...
