char *name;
7 second word, shifted 7
8 second word, shifted 10
D store in both place 1 and place 3; for divul and divsl.
+ B first word, low byte, for branch displacements
+ W second word (entire), for branch displacements
+ L second and third words (entire), for branch displacements
b second word, low byte
- w second word (entire)
+ w second word (entire) [variable word/long branch offset for dbra]
l second and third word (entire)
- g branch offset for bra and similar instructions.
+ g variable branch offset for bra and similar instructions.
The place to store depends on the magnitude of offset.
t store in both place 7 and place 8; for floating point operations
c branch offset for cpBcc operations.
