//-  // Even if the hash table does not contain symbols, we still want to keep the
//-  // section to indicate to a loader that the file exports no symbols. We can't
//-  // have zero buckets because the android loader doesn't support that. We chose
//-  // load factor 4 for the on-disk hash table. For each hash collision, the
//-  // dynamic linker will compare a uint32_t hash value. Since the integer
//-  // comparison is quite fast, we believe we can make the load factor even
//-  // larger. 4 is just a conservative choice.

Thanks!
