How to configure GCC for OpenMP 4.5 offloading to Nvidia PTX GPGPUs

Question

With gcc 7.1 released, we can now configure gcc for openmp 4.5, offloading to Nvidia PTX GPGPUs. That's what they say in the release note (approximately).

So my question is, is there any special flags to activate this configuration when compiling openmp 4.5 to target nvidia devices?

`g++ -O3 -Wall foo.cpp -fopenmp -foffload=nvptx-none -fno-stack-protector` works for me with Ubuntu 17.10. — Z boson, Mar 04 '18 at 15:16
