PTX to LLVM IR

Hi,

I’m aware that there is a PTX *backend* to LLVM. However, what I currently need is a *frontend*. I’ve read about Vinod Grover’s PLANG [1]. However, it seems not to be a part of NVCC (although one or two blogs claim that it’s in). So, is there actually a way/tool to convert PTX to LLVM IR?

Cheers,
Sebastian
