(cgraph_edge_brings_value_p): New parameter dest_val, check if it is not the same as the source val. (cgraph_edge_brings_value_p): New parameter. (gather_edges_for_value): Pass destination value to cgraph_edge_brings_value_p. (perhaps_add_new_callers): Likewise. (get_info_about_necessary_edges): Likewise and exclude values brought only by self-recursive edges. (create_specialized_node): Redirect only clones of self-calling edges. (+self_recursive_pass_through_p): New function. (find_more_scalar_values_for_callers_subset): Use it. (find_aggregate_values_for_callers_subset): Likewise. (known_aggs_to_agg_replacement_list): Removed. (decide_whether_version_node): Re-calculate known constants for all remaining context clones. Modified: trunk/gcc/ChangeLog trunk/gcc/ipa-cp.c
