-- Description:

function Incr (Addr_Reg : Operand) return Operand;
-- Assembler Notation:
-- (An)+
--
-- Description:
-- The address of the operand is in the address register specified
-- by the register field. After the operand address is used, it is
-- incremented by one, two, or four depending upon whether the size
-- of the operand is byte, word, or long word. If the address register
-- is the stack pointer and the operand size is byte, the address is
-- incremented by two rather than one to keep the stack pointer on a
-- word boundary.
function Decr (Addr_Reg : Operand) return Operand;
-- Assembler Notation:

--
-- Description:
-- The address of the operand is in the address register specified

-- decremented by one, two, or four depending upon whether the size
-- of the operand is byte, word, or long word. If the address register

-- d(PC, Rn.SIZE*SCALE)
--
-- Description:
-- The address of the operand is the sum of the address in the address
-- register or PC, the 8-bit displacement, and the contents of the
-- index register (possibly scaled).
function Memory (Pre_Mem : Operand; Od : Integer := 0) return Operand;
-- Assembler Notation:
-- ([bd,An,Ri.SIZE{*SCALE}],od)
-- ([bd,PC,Ri.SIZE{*SCALE}],od)
--
-- Description:
-- The address of the operand is the sum of the pre_mem and a sign-
-- extended outer displacement value od. pre_mem is the sum of the
-- contents of the address register An (or ZAn), the base displacement,
-- and the contents of the index register Ri (or ZRi).
function Memory (Post_Mem : Operand;
Index_Reg : Operand;
Index_Size : Size;
Scale : Integer := 1;
Od : Integer := 0) return Operand;
-- Assembler Notation:
-- ([bd,An],od,Ri.SIZE{*SCALE})
-- ([bd,PC],od,Ri.SIZE{*SCALE})
--
-- Description:
-- The address of the operand is the sum of the post_mem, the contents
-- of the index register Ri (or ZRi), and the outer displacement value
-- od. post_mem is the sum of the base displacement and the contents
-- of the the base register An (or ZAn).
function Absol (Addr : Integer; Addr_Size : Size) return Operand;
-- Assembler Notation:
-- xxx.W
-- xxx.L
--
-- Description:
-- The address of the operand is given.

function "+" (Right : Float) return Operand;
function "-" (Right : Float) return Operand;
function "/" (Left : Operand; Right : Operand) return Operand;
-- Assembler Notation:
-- <list>
--
-- Description:
-- A list of any combination of registers to form a mask.
-- May only be used in the 'movem' and 'fmovem' instructions.
function Ext (Name : String; Disp : Integer := 0) return Operand;
-- Assembler Notation:
-- name
--
-- Description:
-- The name denotes an external symbol. The displacement is added to
-- the value of name.
function "-" (Left, Right : Operand) return Operand;
-- Description:
-- Calculates the difference between two labels.
private
--
-- Implementation specific.
