-;; Special constraints for s/390 machine description:
-;;
-;; a -- Any address register from 1 to 15.
-;; c -- Condition code register 33.
-;; d -- Any register from 0 to 15.
-;; f -- Floating point registers.
-;; t -- Access registers 36 and 37.
-;; G -- Const double zero operand
-;; 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,x: 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. If the letter x
-;; is specified instead of a part number, the constraint matches
-;; if there is any single part with non-default value.
-;; O -- Multiple letter constraint followed by 1 parameter.
-;; s: Signed extended immediate value (-2G .. 2G-1).
-;; p: Positive extended immediate value (0 .. 4G-1).
-;; n: Negative extended immediate value (-4G+1 .. -1).
-;; These constraints do not accept any operand if the machine does
-;; not provide the extended-immediate facility.
-;; P -- Any integer constant that can be loaded without literal pool.
-;; 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.
-;; A -- Multiple letter constraint followed by Q, R, S, or T:
-;; Offsettable memory reference of type specified by second letter.
-;; B -- Multiple letter constraint followed by Q, R, S, or T:
-;; Memory reference of the type specified by second letter that
-;; does *not* refer to a literal pool entry.
-;; U -- Pointer with short displacement.
-;; W -- Pointer with long displacement.
-;; Y -- Shift count operand.
+;; See constraints.md for a description of constraints specific to s390.

;; Special formats used for outputting 390 instructions.
