OpenMP GPU offload

Hi all,

I wanted to know the current status of OpenMP GPU offload in Classic Flang. I used https://github.com/flang-compiler/flang/wiki/Building-Flang to build flang and enabled the option for GPU offload ( -DFLANG_OPENMP_GPU_NVIDIA=ON) . However, I faced compile time errors with simple programs(similar to https://github.com/flang-compiler/flang/issues/847). Any help/suggestions would be appreciated.

Thank you,
Sagar
