Description
Warning: Cannot apply array stencil optimization to variable
in loop because the access pattern could not be determined. Consider splitting the array
into multiple dimensions as this will help the tool better understand the memory layout and
detect the stencil pattern.
Explanation
Stencil optimizations are not applicable when the sliding window buffer moves by more than one element per loop iteration (stride greater than one). In such cases, the optimization cannot provide the expected performance improvement.
