37 -- The node N is an arithmetic node (N_Op_Abs, N_Op_Add, N_Op_Sub,
38 -- N_Op_Div, N_Op_Mul, N_Op_Minus where the operands are in Vax
39 -- float format. This procedure expands the necessary call.
41 procedure Expand_Vax_Comparison
(N
: Node_Id
);
42 -- The node N is an arithmetic comparison node where the types to
43 -- be compared are in Vax float format. This procedure expands the
46 procedure Expand_Vax_Conversion
(N
: Node_Id
);
47 -- The node N is a type conversion node where either the source or
48 -- the target type, or both, are Vax floating-point type.
50 procedure Expand_Vax_Real_Literal
(N
: Node_Id

51 -- The node N is a real literal node where the type is a Vax
52 -- floating-point type. This procedure rewrites the node to eliminate
53 -- the occurrence of such constants.
