- the instruction has room for all the bits of an offset to the operand, whilst the
- extended form is used when an address operand has to be split over n
- instructions. Eg, on the 68k, each move instruction can reference
- the target with a displacement of 16 or 32 bits. On the sparc, move
- instructions use an offset of 14 bits, so the offset is stored in
- the reloc field, and the data in the section is ignored.
