--- Comment #2 from Alex Coplan <acoplan at gcc dot gnu.org> ---
Here is a non-LTO testcase that fails with -O -ftree-vectorize
-march=armv8.2-a+sve --param=aarch64-autovec-preference=3:

extern char a[], b[];
short c, d;
long *e;
void f() {
  for (int g; g < c; g += 1) {
    a[g] = d;
    b[g] = e[g];
  }
}
