! This checks that the basic functionality of map type present functions as
! expected, emitting an omptarget error when the data is not present.
! REQUIRES: flang, amdgpu
! RUN: %libomptarget-compile-fortran-generic
! RUN: %libomptarget-run-fail-generic 2>&1 \

! NOTE: This should intentionally fatal error in omptarget as it's not
! present, as is intended.
