------- Additional Comments From jakub at redhat dot com 2005-08-19 18:51 ------- It can't be inserted just on abnormal critical edges: gcc_assert (!((e->flags & EDGE_ABNORMAL) && EDGE_CRITICAL_P (e))); So I guess we could insert it on the EH edges if !EDGE_CRITICAL_P and only only avoid caller-saving it if EDGE_CRITICAL_P.
