   '.' 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 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
       possible, so it should not be used except for the SunFPA.  */
