  /* IMPLEMENTATION NOTES.
   *
   * The 32-bit hash algorithms share a common byte-order neutral collector and
   * padding function implementations that operate on unaligned data,
   * ../md32_common.h. This SHA-512 implementation does not. Reasons
   * [in reverse order] are:
   *
   * - It's the only 64-bit hash algorithm for the moment of this writing,
   *   there is no need for common collector/padding implementation [yet];
   * - By supporting only a transform function that operates on *aligned* data
   *   the collector/padding function is simpler and easier to optimize. */
