/* Meaning of CODE:
f -- float insn (print a CONST_DOUBLE as a float rather than in hex).

L,W,B,Q,S,T -- print the opcode suffix for specified size of operand.
C -- print opcode suffix for set/cmov insn.
N -- like C, but print reversed condition
c -- like C, but print reversed condition
F -- print opcode suffix for fcmov insn.
f -- like C, but print reversed condition
R -- print the prefix for register names.
z -- print the opcode suffix for the size of the current operand.
* -- print a star (in certain assembler syntax)

J -- print the appropriate jump operand.
s -- print a shift double count, followed by the assemblers argument
delimiter.
b -- print the QImode name of the register for the indicated operand.
%b0 would print %al if operands[0] is reg 0.
w -- likewise, print the HImode name of the register.
k -- likewise, print the SImode name of the register.
h -- print the QImode name for a "high" register, either ah, bh, ch or dh.
y -- print "st(0)" instead of "st" as a register.
P -- print as a PIC constant
