If I'm right, Stanislav Mekhanoshin has asked for the intermediate temporary files (such as IL and ISA code) that can be generated during kernel building/compilation. You can dump/save those temporary files using build option "-save-temps[=<prefix>]" . For more details, please refer the section "3.4 AMD-Developed Supplemental Compiler Options" in AMD programming user guide.
Right, dumps made with -save-temps=<prefix> is what is needed for the analysis. The easiest way to get them is by setting env AMD_OCL_BUILD_OPTIONS_APPEND=-save-temps=dump before the app run.
