 // Relocation information
 
 
 // Relocation information consists of the address (pc) of the datum
 // to which the relocation information applies, the relocation mode
 // (rmode), and an optional data field. The relocation mode may be
 // "descriptive" and not indicate a need for relocation, but simply
 // describe a property of the datum. Such rmodes are useful for GC
 // and nice disassembly output.
