Some value is missing in transforming such as '((__u64)0xAA)'

[Unlimited-Witchcraft]

When I transfrom some C linux system file.

#define UFFD_API ((__u64)0xAA)
#define UFFD_API_FEATURES (UFFD_FEATURE_EVENT_FORK |        \
               UFFD_FEATURE_EVENT_REMAP |       \
               UFFD_FEATURE_EVENT_REMOVE |  \
               UFFD_FEATURE_EVENT_UNMAP |       \
               UFFD_FEATURE_MISSING_HUGETLBFS | \
               UFFD_FEATURE_MISSING_SHMEM |     \
               UFFD_FEATURE_SIGBUS |        \
               UFFD_FEATURE_THREAD_ID)
#define UFFD_API_IOCTLS             \
    ((__u64)1 << _UFFDIO_REGISTER |     \
     (__u64)1 << _UFFDIO_UNREGISTER |   \
     (__u64)1 << _UFFDIO_API)
#define UFFD_API_RANGE_IOCTLS           \
    ((__u64)1 << _UFFDIO_WAKE |     \
     (__u64)1 << _UFFDIO_COPY |     \
     (__u64)1 << _UFFDIO_ZEROPAGE)
#define UFFD_API_RANGE_IOCTLS_BASIC     \
    ((__u64)1 << _UFFDIO_WAKE |     \
     (__u64)1 << _UFFDIO_COPY)

Those values above are all missing.

Dupe of #316. This is hard because how C macros work... You really don't know the value until the macro is evaluated in a context.

But this has a very easy workaround which is using it in a constant somewhere, which bindgen would understand, so:

static const uint64_t kUffdApiRangeIoctls = UFFD_API_RANGE_IOCTLS; // Or whatever name you want

Then it'd work.

Thank you for reply.
