Thanks for the information. I did find the cross compiler. 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.
