Thanks for your reply! I am certain that addresses addr1 and addr2 never overlap, and the opencl version is 16.0.

But in the Intel FPGA for OpenCL Best Practices Guide, I see

"The array specified by the ivdep pragma must be a local or private memory array, or a pointer variable that points to a global, local, or private memory storage. If the specified array is a pointer, the ivdep pragma also applies to all arrays that may alias with specified pointer."

So, I think "Pragma unroll" can work on local memory? Is right?

Thank you!
