I will try to see if I can build the native Xeon Phi compiler if I can get hold of their patches. I am not interested the floating point instructions as much, I just want to use gcc to create a proof of concept work. Hopefully as GCC support matures it can be used as the mainstream compiler as opposed to the Intel Compilers. P.S: I am not subscribed to the list so would appreciate if I am copied in the replies. -- Bharath
