'#' for an immediate operand prefix (# in MIT and Motorola syntax

'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

'x' for float insn (print a CONST_DOUBLE as a float rather than in hex),

'y' for a FPA insn (print pair of registers as rx:ry). This also outputs
