| procedure Expand_Vax_Arith (N : Node_Id); |

| -- 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. |
