37 * The default merge_pair_func implementation, simply copies the debug info
38 * from the old Firm node to the new one if the new one does not have debug info yet.
40 * @param nw The new Firm node.
41 * @param old The old Firm node.
42 * @param info The action that cause old node to be replaced by new one.

47 * The default merge_sets_func implementation. If n_old_nodes is equal 1,
48 * copies the debug info from the old node to all new ones (if they do not have
49 * one), else does nothing.
51 * @param new_nodes An array of new Firm nodes.
52 * @param n_new_nodes The length of the new_nodes array.
53 * @param old_nodes An array of old (replaced) Firm nodes.
54 * @param n_old_nodes The length of the old_nodes array.
55 * @param info The action that cause old node to be replaced by new one.
