Signed-off-by: Trevor Saunders gcc/ChangeLog: * cgraph.c (cgraph_node::collect_callers): Return auto_vec. * cgraph.h (cgraph_node::collect_callers): Likewise. * ipa-cp.c (create_specialized_node): Adjust. (decide_about_value): Likewise. (decide_whether_version_node): Likewise. * ipa-sra.c (process_isra_node_results): Likewise.
