! -foffload-device tells the frontend we are compiling for the auxiliary target,
! i.e. not the host device. Test for CUDA and OpenMP offloading modes.

! RUN: %flang -target aarch64-linux-gnu --no-offloadlib --offload-arch=sm_80 --offload-arch=gfx90a %s -fopenmp -### 2>&1 | FileCheck %s --check-prefixes=CHECK,OPENMP
! RUN: %flang -target aarch64-linux-gnu --no-offloadlib --offload-arch=sm_80 -xcuda %s -### 2>&1 | FileCheck %s --check-prefixes=CHECK,CUDA

! Compiled as CUDA, device-compilation is done first
