- '@' for a reference to the top word on the stack:
- sp@, (sp) or (%sp) depending on the style of syntax.

- '&' for the letter `d' in an op code, but only on the 68040.

- '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),
