I compiled with `flang -fopenmp --offload-arch=sm_120 -fopenmp-version=52 main.F90`. Running with `LIBOMPTARGET_INFO=-1 ./a.out` shows that offloading is happening.

Unfortunately I don't have access to an NVIDIA card, please do try the offload mandatory just incase. However, can you share the map entries the trace produces? From my understanding nothing the compiler emits at a Flang -> LLVM-IR lowering level should produce the extra mappings required for the pointers data to be mapped, and there isn't anything we produce that I'm aware of that's NVIDIA specific that would cause a deep-copy here.
