```
    case VEC_PERM_EXPR:
      {
        expand_operands (treeop0, treeop1, target, &op0, &op1, EXPAND_NORMAL);
        vec_perm_builder sel;
        if (TREE_CODE (treeop2) == VECTOR_CST
            && tree_to_vec_perm_builder (&sel, treeop2))
          {
            machine_mode sel_mode = TYPE_MODE (TREE_TYPE (treeop2));
            temp = expand_vec_perm_const (mode, op0, op1, sel,
                                          sel_mode, target);
          }
        else
          {
            op2 = expand_normal (treeop2);
            temp = expand_vec_perm_var (mode, op0, op1, op2, target);
          }
        gcc_assert (temp);
        return temp;
      }
```

I suspect it is either a vectorizer issue or a target issue.
