flang/test/Driver/omp-driver-offload.f90

! Test that flang-new OpenMP and OpenMP offload related 
! commands forward or expand to the appropriate commands 
! for flang-new -fc1 as expected. Assumes a gfx90a, aarch64,
! and sm_70 architecture, but doesn't require one to be 
! installed or compiled for, just testing the appropriate 
! generation of jobs are created with the correct 
! corresponding arguments.
