--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
It does sth for me:

obj-aarch64-g/gcc> ./xgcc -B. t.c -I include -S -O3 -march=armv9-a+sve
-fopt-info-vec -fno-vect-cost-model
t.c:13:27: optimized: loop vectorized using 16 byte vectors and unroll factor 4
t.c:13:27: optimized:  loop versioned for vectorization to enhance alignment
t.c:16:18: optimized: basic block part vectorized using 16 byte vectors
