13 * debugging support. It only guarantees that the Firm library compiles
14 * and runs without any real debugging support.

23 * The default merge_pair_func implementation, simply copies the debug info
24 * from the old Firm node to the new one if the new one does not have debug info yet.
26 * @param nw The new Firm node.
27 * @param old The old Firm node.
28 * @param info The action that cause old node to be replaced by new one.
30 void default_dbg_info_merge_pair(ir_node *nw, ir_node *old, dbg_action info);
33 * The default merge_sets_func implementation. If n_old_nodes is equal 1,
34 * copies the debug info from the old node to all new ones (if they do not have
35 * one), else does nothing.
37 * @param new_nodes An array of new Firm nodes.
38 * @param n_new_nodes The length of the new_nodes array.
39 * @param old_nodes An array of old (replaced) Firm nodes.
40 * @param n_old_nodes The length of the old_nodes array.
41 * @param info The action that cause old node to be replaced by new one.
