   --  The node N is an arithmetic node (N_Op_Abs, N_Op_Add, N_Op_Sub,
   --  N_Op_Div, N_Op_Mul, N_Op_Minus where the operands are in Vax
   --  float format. This procedure expands the necessary call.

   procedure Expand_Vax_Comparison (N : Node_Id);
   --  The node N is an arithmetic comparison node where the types to
   --  be compared are in Vax float format. This procedure expands the
   --  necessary call.

   procedure Expand_Vax_Conversion (N : Node_Id);
   --  The node N is a type conversion node where either the source or
   --  the target type, or both, are Vax floating-point type.

   procedure Expand_Vax_Real_Literal (N : Node_Id);
   --  The node N is a real literal node where the type is a Vax
   --  floating-point type. This procedure rewrites the node to eliminate
   --  the occurrence of such constants.
