;; Special constraints for s/390 machine description:
;;
;;    a -- Any address register from 1 to 15.
;;    d -- Any register from 0 to 15.
;;    I -- An 8-bit constant (0..255).
;;    J -- A 12-bit constant (0..4095).
;;    K -- A 16-bit constant (-32768..32767).
;;    Q -- A memory reference without index-register.
;;    S -- Valid operand for the LARL instruction.
;;
;; Special formats used for outputting 390 instructions.
;;
;;   %b -- Print a constant byte integer.               xy
;;   %h -- Print a signed 16-bit.                       wxyz
;;   %N -- Print next register (second word of a DImode reg) or next word.
;;   %M -- Print next register (second word of a TImode reg) or next word.
;;   %O -- Print the offset of a memory reference (PLUS (REG) (CONST_INT)).
;;   %R -- Print the register of a memory reference (PLUS (REG) (CONST_INT)).
;;
;; We have a special constraint for pattern matching.
;;
;;   s_operand -- Matches a valid S operand in a RS, SI or SS type instruction.
