Description
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 I found that fail running several times the tests
tasking/issue-69733.c
tasking/issue-87307.c
tasking/issue-94260-1.cpp
tasking/issue-50602.c
tasking/hidden_helper_task/affinity.cpp
tasking/hidden_helper_task/gtid.cpp
tasking/task_teams_stress_test.cpp
