Check instruction sets tensorflow build is compiled with

Question

I am looking for a way to confirm that a tensorflow wheel was compiled with the correct instructions.

I am trying to build tensorflow for a Intel Atom CPU. I know that bazel will detect and build with appropriate instructions automatically, but I don't want to run the build on the Atom CPU because it is very slow. So I am running bazel on a i7 CPU with custom instructions instead. After obtaining the wheel, I would like to confirm that the instructions were actually used.

I found some python api that allows me to check MKL and other stuff, but don't know how to check for cpu instructions like sse. Any help please?

from tensorflow.python.framework import test_util as test

if __name__ == "__main__":
    print('MKL enabled: %s' % test.IsMklEnabled())
    print('Google cuda enabled: %s' % test.IsGoogleCudaEnabled())
    print('GPU available: %s' % test.is_gpu_available())

    # cpu instruction set?
