44 * with One Return(Phi).
45 * This is the preferred input for the if-conversion.
47 * In pseudocode, it means:
62 void normalize_one_return(ir_graph *irg);
65 * Normalize the Returns of a graph by moving
66 * the Returns upwards as much as possible.
67 * This might be preferred for code generation.
69 * In pseudocode, it means:
84 void normalize_n_returns(ir_graph *irg);
