In the report generated of my opencl kernel, in the area analysis tab of the report I see one line which gives resource utilization for " No source Line", like the one I have added below. I cannot understand where is this hardware utilized, can anyone provide more information about this line ?
"No source line" refers to cases where some resource is being used for operations that do not necessarily map to any line in your code; e.g. registers and FIFOs used to balance the latency of pipeline stages. However, such large area usage in "No source line" is likely the result of a bug. Try to generate the report using a newer version of the compiler and you might get the correct location where those resources are being used. Older versions of the compiler (before 18.0) have a lot of such bugs in the report.
