[Bug tree-optimization/38968] Complex matrix product is not vectorized

This is somewhat expected.  We vectorize the complex product using vectors
of real parts and vectors of complex parts of two complex numbers (so we
are not using the fancy haddsub SSE codes).  Did you try enabling SSE3 btw?
Can you post the ifort assembly of the loop?
