'-' for an operand pushing on the stack:

'+' 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).
|
||
'!' for the fpcr register (used in some float-to-fixed conversions).
|
||
'$' for the letter `s' in an op code, but only on the 68040.
|
||
'&' 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),
|
||
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
