;; Extra register constraints are:
;;   'b'   EAM register mdb
;;   'c'   EAM register mdc
;;   'f'   Floating-point register
;;   'k'   Register that can be used as the target of a sibcall, i.e. call-used
;;         general register not clobbered in the epilogue: r1-r8 and r10
;;   'l'   Low general register, i.e. general register accessible in user mode
;;         on the GR6 and, consequently, that can be used as the target of a
;;         branch with prediction: r1-r28
;;   't'   Register r1
;;   'u'   Register r2
;;   'v'   Register r3
;;
;; Immediate integer operand constraints are:
;;   'J'  0 .. 65535     (16-bit immediate)
;;   'K'  1 .. 31        (5-bit immediate)
;;   'L'  -1 .. -65535   (16-bit negative immediate)
;;   'M'  -1             (minus one)
;;   'O'  0              (integer zero)
;;   'P'  32             (thirty two)
;;
;; Immediate FP operand constraints are:
;;   'G'  0.0            (floating-point zero)
;;
;; Operand substitution characters are:
;;   %#   delay slot follows, if empty, fill with NOP
;;   %b   LS 8 bits of immediate operand
;;   %w   LS 16 bits of immediate operand
;;   %u   MS 16 bits of immediate operand
;;   %r   register or zero (r0)
;;   %f   FP register or zero (f0)
;;   %d   second register in a pair

;; integers must in general be kept out of the floating-point registers.

;; occupy such registers. To disguise this from the compiler, UNSPECs are
;; used for floating-point operations on integers and floating from general
;; register to floating-point register and fixing in the reverse direction
