"/home/guoshichao/work_profile/vela_os/vela_car_5/nuttx/include/nuttx/crypto/blake2s.h", line 91: error #2118-D:
          this attribute reduces the alignment of the typedef, and while that
          will be respected for struct/field layout, the compiler will not
          generate code to handle misaligned accesses for objects of this type
  typedef uint32_t uint32_alias_t __attribute__((may_alias)) aligned_data(1);
                                                             ^
