How to use SSE/SSE2 instructions when programming with QNX?
 I want to accelerate my massive computation with SSE instructions  in my QNX program. How can I deal with it?

( In Linux or windows  we can include <xmmintrin.h> or some other heads . Then we can use functions like _mm_add_ps() to
 invoke SSE/SSE2 instructions . How can I do the same in QNX mometntics IDE? )
