I've compiled LLVM in Release and tried to pass libomp tests with passive policy running the following command:
`CHECK_OPENMP_ENV='OMP_WAIT_POLICY=passive' ninja check-openmp`
It turns out that some of them don't end. Here is a list of all if found that fail running several times the tests

tasking/hidden_helper_task/gtid.cpp

I'm running in a cluster with the following lcpu:
