offload/test/offloading/fortran/optional-mapped-arguments-3.f90

! OpenMP offloading test that checks we do not cause a segfault when mapping
! optional function arguments (present or otherwise). No results requiring
! checking other than that the program compiles and runs to completion with no
! error. This particular variation checks that we're correctly emitting the
! load/store in both branches mapping the input array.
! REQUIRES: flang, amdgpu
