Hi, I'm really interested in the new CSSPGO tool, can anyone give me some more detailed instructions about how to generate the perfscript file it needs, I tried to first use "perf record -e xxx -b ..." to generate a perf.data file and then use "perf script" to dump all the text into a perfscript file, but it seems to be different from the perfscript under the llvm/test/tools/llvm-profgen/Inputs directory.
