Run the following commands:

git clone http://github.com/tensorflow/tensorflow

unfortunately, there may be some dependencies to be installed here
then

bazel build --experimental_generate_json_trace_profile --experimental_profile_cpu_usage --profile=~/llvm.profile.gz --nobuild @llvm-project//llvm:FileCheck
