CODE is a letter or dot (`z' in `%z0') or 0 if no letter was specified.
For `%' followed by punctuation, CODE is the punctuation and X is null.
On the 68000, we use several CODE characters:
'.' for dot needed in Motorola-style opcode names.
'-' 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 cc register (used in an `and to cc' insn).
'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
possible, so it should not be used except for the SunFPA. */
