32 * Normalize the Returns of a graph by creating a new End block
33 * with One Return(Phi).
34 * This is the preferred input for the if-conversion.
36 * In pseudocode, it means:
51 void normalize_one_return(ir_graph *irg);
54 * Normalize the Returns of a graph by moving
55 * the Returns upwards as much as possible.
56 * This might be preferred for code generation.
58 * In pseudocode, it means:
73 void normalize_n_returns(ir_graph *irg);
