- On the 68000, we use several CODE characters:

- '-' for an operand pushing on the stack:
- sp@-, -(sp) or -(%sp) depending on the style of syntax.
- '+' for an operand pushing on the stack:
- sp@+, (sp)+ or (%sp)+ depending on the style of syntax.
- '@' for a reference to the top word on the stack:
- sp@, (sp) or (%sp) depending on the style of syntax.
- '#' for an immediate operand prefix (# in MIT and Motorola syntax
- but & in SGS syntax, $ in unos syntax).
- '!' for the fpcr register (used in some float-to-fixed conversions).
-
- 'b' for byte insn (no effect, on the Sun; this is for the ISI).
- 'd' to force memory addressing to be absolute, not relative.
- 'f' for float insn (print a CONST_DOUBLE as a float rather than in hex)
- 'w' for FPA insn (print a CONST_DOUBLE as a SunFPA constant rather
- than directly). Second part of 'y' below.
- 'x' for float insn (print a CONST_DOUBLE as a float rather than in hex),
- or print pair of registers as rx:ry.
- 'y' for a FPA insn (print pair of registers as rx:ry). This also outputs
- CONST_DOUBLE's as SunFPA constant RAM registers if
