;; Special constraints for 370 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).
;;
;; Special formats used for outputting 370 instructions.
;;
;;   %B -- Print a constant byte integer.
;;   %H -- Print a signed 16-bit constant.
;;   %L -- Print least significant word of a CONST_DOUBLE.
;;   %M -- Print most significant word of a CONST_DOUBLE.
;;   %N -- Print next register (second word of a DImode reg).
;;   %O -- Print the offset of a memory reference (PLUS (REG) (CONST_INT)).
;;   %R -- Print the register of a memory reference (PLUS (REG) (CONST_INT)).
;;   %X -- Print a constant byte integer in hex.
;;
;; We have a special constraint for pattern matching.
;;
;;   s_operand -- Matches a valid S operand in a RS, SI or SS type instruction.
;;
;;   r_or_s_operand -- Matches a register or a valid S operand in a RS, SI
;;		       or SS type instruction or a register
;;
;; For MVS C/370 we use the following stack locations for:
;;
;;   136 - internal function result buffer
;;   140 - numeric conversion buffer
;;   144 - pointer to internal function result buffer
;;   148 - start of automatic variables and function arguments
;;
;; To support programs larger than a page, 4096 bytes, PAGE_REGISTER points
;; to a page origin table, all internal labels are generated to reload the
;; BASE_REGISTER knowing what page it is on and all branch instructions go
;; directly to the target if it is known that the target is on the current
;; page (essentially backward references).  All forward references and off
;; page references are handled by loading the address of target into a
;; register and branching indirectly.
;;
;; Some *di patterns have been commented out per advice from RMS, as gcc
;; will generate the right things to do.
