You should now have a few ``*.profdata`` files in + b. You should now have a few ``*.profraw`` files in ``path/to/stage2/profiles/``. You need to merge these using ``llvm-profdata`` (even if you only have one! The profile merge transforms profraw into actual profile data, as well). This can be done with - ``/path/to/stage1/llvm-profdata -merge - -output=/path/to/output/profdata.prof path/to/stage2/profiles/*.profdata``. + ``/path/to/stage1/llvm-profdata merge + -output=/path/to/output/profdata.prof path/to/stage2/profiles/*.profraw``. 4. Now, build your final, PGO-optimized Clang. To do this, you'll want to pass the following additional arguments to CMake. |
