+ 16->h, 32->w.

+ 'm': Print a condition (eq, ne, etc).
+ 'M': Same as 'm', but invert condition.
+ 'b/h/s/d/q': Print a scalar FP/SIMD register name.
+ 'S/T/U/V': Print a FP/SIMD register name for a register list.
+ The register printed is the FP/SIMD register name
+ of X + 0/1/2/3 for S/T/U/V.
+ 'R': Print a scalar FP/SIMD register name + 1.
+ 'X': Print bottom 16 bits of integer constant in hex.
+ 'w/x': Print a general register name or the zero register
+ (32-bit or 64-bit).
+ '0': Print a normal operand, if it's a general register,
+ then we assume DImode.
+ 'k': Print NZCV for conditional compare instructions.
+ 'A': Output address constant representing the first
+ argument of X, specifying a relocation offset
+ if appropriate.
+ 'L': Output constant address specified by X
+ with a relocation offset if appropriate.
+ 'G': Prints address of X, specifying a PC relative
+ relocation mode if appropriate. */
