      Overview:

      +The 'llvm.bwsap' family of intrinsics is used to byteswap a 16, 32 or +64 bit quantity. These are useful for performing operations on data that is not +in the target's native byte order. +

      + +
      Semantics:
      + +

      +The llvm.bswap.16 intrinsic returns a ushort value that has the high and low +byte of the input ushort swapped. Similarly, the llvm.bswap.i32 intrinsic +returns a uint value that has the four bytes of the input uint swapped, so that +if the input bytes are numbered 0, 1, 2, 3 then the returned uint will have its +bytes in 3, 2, 1, 0 order. The llvm.bswap.i64 intrinsic extends this concept +to 64 bits. +
