34 * The famous clear_link() walker-function.
35 * Do not implement it by yourself, use this one
37 void firm_clear_link(ir_node *n, void *env);
40 * Copies a node to a new irg. The Ins of the new node point to
41 * the predecessors on the old irg. n->link points to the new node.
43 * @param n The node to be copied
44 * @param irg the new irg
46 * Does NOT copy standard nodes like Start, End etc that are fixed
47 * in an irg. Instead, the corresponding nodes of the new irg are returned.
48 * Note further, that the new nodes have no block.
