| 24 ;; Special constraints for s/390 machine description: | |
| 25 ;; | |
| 26 ;; a -- Any address register from 1 to 15. | |
| 27 ;; b -- Memory operand whose address is a symbol reference or a symbol | |
| 28 ;; reference + constant which can be proven to be naturally aligned. | |
| 29 ;; c -- Condition code register 33. | |
| 30 ;; d -- Any register from 0 to 15. | |
| 31 ;; f -- Floating point registers. | |
| 32 ;; t -- Access registers 36 and 37. | |
| 33 ;; C -- A signed 8-bit constant (-128..127) | |
| 34 ;; D -- An unsigned 16-bit constant (0..65535) | |
| 35 ;; G -- Const double zero operand | |
| 36 ;; I -- An 8-bit constant (0..255). | |
| 37 ;; J -- A 12-bit constant (0..4095). | |
| 38 ;; K -- A 16-bit constant (-32768..32767). | |
| 39 ;; L -- Value appropriate as displacement. | |
| 40 ;; (0..4095) for short displacement | |
| 41 ;; (-524288..524287) for long displacement | |
| 42 ;; M -- Constant integer with a value of 0x7fffffff. | |
| 43 ;; N -- Multiple letter constraint followed by 4 parameter letters. | |
| 44 ;; 0..9,x: number of the part counting from most to least significant | |
| 45 ;; H,Q: mode of the part | |
| 46 ;; D,S,H: mode of the containing operand | |
| 47 ;; 0,F: value of the other parts (F - all bits set) | |
| 48 ;; | |
| 49 ;; The constraint matches if the specified part of a constant | |
| 50 ;; has a value different from its other parts. If the letter x | |
| 51 ;; is specified instead of a part number, the constraint matches | |
| 52 ;; if there is any single part with non-default value. | |
| 53 ;; O -- Multiple letter constraint followed by 1 parameter. | |
| 54 ;; s: Signed extended immediate value (-2G .. 2G-1). | |
| 55 ;; p: Positive extended immediate value (0 .. 4G-1). | |
| 56 ;; n: Negative extended immediate value (-4G+1 .. -1). | |
| 57 ;; These constraints do not accept any operand if the machine does | |
| 58 ;; not provide the extended-immediate facility. | |
| 59 ;; P -- Any integer constant that can be loaded without literal pool. | |
| 60 ;; Q -- Memory reference without index register and with short displacement. | |
| 61 ;; R -- Memory reference with index register and short displacement. | |
| 62 ;; S -- Memory reference without index register but with long displacement. | |
| 63 ;; T -- Memory reference with index register and long displacement. | |
| 64 ;; A -- Multiple letter constraint followed by Q, R, S, or T: | |
| 65 ;; Offsettable memory reference of type specified by second letter. | |
| 66 ;; B -- Multiple letter constraint followed by Q, R, S, or T: | |
| 67 ;; Memory reference of the type specified by second letter that | |
| 68 ;; does *not* refer to a literal pool entry. | |
| 36 | 69 ;; U -- Pointer with short displacement. (deprecated - use ZQZR) |
| 70 ;; W -- Pointer with long displacement. (deprecated - use ZSZT) | |
| 0 | 71 ;; Y -- Shift count operand. |
| 36 | 72 ;; ZQ -- Pointer without index register and with short displacement. |
| 73 ;; ZR -- Pointer with index register and short displacement. | |
| 74 ;; ZS -- Pointer without index register but with long displacement. | |
| 75 ;; ZT -- Pointer with index register and long displacement. | |
