Yes - there is no vector type for complex double. But the vectorizer could query for a vector type for the complex component type (double) and divide the vector element count by 2 (for complex) to get the vectorization factor which would be 1 here. Should SLP the be possible for that loop? Richard. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40770
