Description

Warning: [HLS 214-354] Cannot apply performance pragma because it is not attached to any loop or the original loop may be fully unrolled.

Explanation

Check the pragma or directive settings to see where the performance pragma is being applied and whether the loop where the performance pragma is being specified is also being unrolled. The unroll transformation will remove the loop and therefore the performance pragma will no longer be in a loop body.
