Anyways I don't there is any bug here in the middle-end because the alignme= nt is what the backend requests. Now the question is the alignment needed or n= ot, that is for some x86 person to do benchmarking really. And if this needs mo= re than the simple heurstics than what is currently supported in the middle-end well that is still up to the Intel/AMD person to benchmark.=
