| -- 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. |

| procedure Expand_Vax_Valid (N : Node_Id); |
| -- The node N is an attribute reference node for the Valid attribute where |
| -- the prefix is of a Vax floating-point type. This procedure expands the |
| -- necessary call for the validity test. |
