Using Nvbit for a specific region of code

[mahmoodn]

Hi
Is there anyway to invoke nvbit instrumentation at a specific section? For example, in Nsight Compute, it is possible to mark start and finish regions with

    cudaProfilerStart();
    mlperf::StartTest(sut.get(), qsl.get(), test_settings, log_settings);
    cudaProfilerStop();

and then execute the profiler with --profile-from-start off.
Is there a similar way with Nvbit?
