39 -- N_Op_Div, N_Op_Mul, N_Op_Minus where the operands are in Vax
40 -- float format. This procedure expands the necessary call.
42 procedure Expand_Vax_Comparison (N : Node_Id);
43 -- The node N is an arithmetic comparison node where the types to
44 -- be compared are in Vax float format. This procedure expands the
45 -- necessary call.

49 -- the target type, or both, are Vax floating-point type.

53 -- floating-point type. This procedure rewrites the node to eliminate
