This sample is a simple LD_PRELOAD based tool that allows to collect OpenCL kernel sources, binaries and symbols to correlate them. This tool works for Intel(R) Processor Graphics only.
As a result, listing like the following will be printed for each kernel (once per kernel creation).

Run the following commands to build the sample:
cd <pti>/samples/cl_debug_info
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
makeUse this command line to run the tool:
./cl_debug_info <target_application>One may use cl_gemm as target application:
./cl_debug_info ../../cl_gemm/build/cl_gemm gpuUse Microsoft* Visual Studio x64 command prompt to run the following commands and build the sample:
cd <pti>\samples\cl_debug_info
mkdir build
cd build
cmake -G "NMake Makefiles" -DCMAKE_BUILD_TYPE=Release -DCMAKE_LIBRARY_PATH=<opencl_icd_lib_path>;<iga_lib_path> ..
nmakeUse this command line to run the tool:
cl_debug_info.exe <target_application>One may use cl_gemm as target application:
cl_debug_info.exe ..\..\cl_gemm\build\cl_gemm.exeNote: to build this sample one may need to generate *.lib file from IGA *.dll (see here for details) and provide the path to this *.lib to cmake with -DCMAKE_LIBRARY_PATH.
Also one may need to add an actual path to IGA *.dll into PATH before sample run, e.g.:
set PATH=%PATH%;<iga_dll_path>
cl_debug_info.exe ..\..\cl_gemm\build\cl_gemm.exe
