Thank you for your answer
It helped me understand what vec_dst does, but i am still confused on how to calculate prefetch constatnt which has to be passed in vec_dst.
If you can help me with an example then that would be great.
Could you please clarify, what you mean by "prefetch constant"?
while using vec_dst instruction we have to pass 3 parameters to it i.e. address, prefetch constant(data block to be pre-fetched) and stream.
i am not able to calculated the second parameter that should be given to the vec_dst.
i had refer this document earlier but still i am not able to clarify my doubt on vec_dst.
