  15 // RELOC - Check the relocation in the object.
  16 // FIXUP - Check the fixup on the instruction.
  17 // ENCBE - Check the big-endian encoding on the instruction.

  19 // ????? - Placeholder. Relocation is defined but the way of generating it is
  20 //         unknown.
  21 // FIXME - Placeholder. Generation method is known but doesn't work.
