;; %S: print S-type memory reference (base+displacement).
;; %N: print the second word of a DImode operand.
;; %M: print the second word of a TImode operand.
;; %Y: print shift count operand.
;;
;; %b: print integer X as if it's an unsigned byte.
;; %x: print integer X as if it's an unsigned halfword.
;; %h: print integer X as if it's a signed halfword.
;; %i: print the first nonzero HImode part of X.
