- * Introduce several copies for one node.
- *
- * A copy in this context means, that you want to introduce several new
- * abstract values (in Firm: nodes) for which you know, that they
- * represent the same concrete value. This is the case if you
- * - copy
- * - spill and reload
- * - re-materialize
- * a value.
- *
- * This function reroutes all uses of the original value to the copies in the
- * corresponding dominance subtrees and creates Phi functions where necessary.
- *
- * @note The visited flag and link fields are used.
- *
- * @param info           Dominance frontier information.
- * @param lv          Liveness information to be updated. If NULL, no liveness
- *                    updating is performed.
- * @param value       The value that has been duplicated.
- * @param copies_len  the length of the copies array
- * @param copie       an array holding all copies of the value
- * @param phis        An ARR_F where all newly created phis will be inserted,
- *                    may be NULL
- * @param ignore_uses A set of nodes probably using one of the nodes in
- *                    @p nodes. Their usage will not adjusted. They remain
- *                    untouched by this function. May be NULL.
