;; 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).
;;    L -- Value appropriate as displacement.
;;         (0..4095) for short displacement
;;         (-524288..524287) for long displacement
;;    M -- Constant integer with a value of 0x7fffffff.
;;    N -- Multiple letter constraint followed by 4 parameter letters.
;;         0..9:  number of the part counting from most to least significant
;;         H,Q:   mode of the part
;;         D,S,H: mode of the containing operand
;;         0,F:   value of the other parts (F - all bits set)
;;
;;         The constraint matches if the specified part of a constant
;;         has a value different from its other parts.
;;    Q -- Memory reference without index register and with short displacement.
;;    R -- Memory reference with index register and short displacement.
;;    S -- Memory reference without index register but with long displacement.
;;    T -- Memory reference with index register and long displacement.
;;    U -- Pointer with short displacement.
;;    W -- Pointer with long displacement.
;;    Y -- Shift count operand.
;;
;; Special formats used for outputting 390 instructions.
;;
;;     %C: print opcode suffix for branch condition.
;;     %D: print opcode suffix for inverse branch condition.
;;     %J: print tls_load/tls_gdcall/tls_ldcall suffix
;;     %O: print only the displacement of a memory reference.
;;     %R: print only the base register of a memory reference.
;;     %N: print the second word of a DImode operand.
;;     %M: print the second word of a TImode operand.

;;     %b: print integer X as if it's an unsigned byte.
;;     %x: print integer X as if it's an unsigned word.
;;     %h: print integer X as if it's a signed word.
;;     %i: print the first nonzero HImode part of X
;;     %j: print the first HImode part unequal to 0xffff of X

;;
;; We have a special constraint for pattern matching.
;;
;;   s_operand -- Matches a valid S operand in a RS, SI or SS type instruction.
