Flang target not implemented?

I updated my local git repo today, and built fresh compilers (clang and flang-new) with openmp target offload. I tried a build, and got the following error. I’m doing the build on an Intel Cascade Lake server with an Nvidia V100 GPU. Can anyone help with the following error?

$ flang-new -c -fopenmp -fopenmp-targets=nvptx64 lu_data.f90
error: /nobackupnfs1/jcbecker/llvm-project/flang/lib/Optimizer/CodeGen/Target.cpp:411: not yet implemented: target not implemented

Target offloading hasn’t been implemented in LLVM’s Flang yet, it’s still a work in progress. You’ll need to use one of the vendor compilers for Fortran code at the moment. I remember @jdoerfert and others planning on the support.
