[Bug rtl-optimization/31485] C complex numbers, amd64 SSE, missed optimization opportunity

Has any work been done on this enhancement?  I'm using gcc 4.3.2, and I noticed
that there is still limited use of SSE instructions for complex arithmetic.  

Unless I'm missing something in my understanding, wouldn't the ideal for all
_Complex double additions with SSE2 be to use addpd, and movapd or movupd for
memory operations?
