See the answer on the GitHub page: By default the C++ compiler compiles for a "generic" CPU, where the LLVM backend is configurated to produce code for the "native" CPU (that one where the code will actually run). This usually explains this kind of differences. You can try to use -march=native and also '-Ofast' in the C++ compiler, to have the same options the LLVM backend is using.
