[llvm-dev] How to use llvm to compile CUDA to IR?

[Hugh Perkins via llvm-dev]

adding `-emit-llvm` causes ir to be emitted, instead of ptx.  However, it's
only emitting the host-side ir, and I need device side ir.  (Well... I need
both, but device side is pretty high priority...). Currently I'm doing:

clang++-3.8 -I/usr/local/cuda-7.5/include llvm-sample.cu -emit-llvm -S -o
llvm-sample.ll

How to emit device-side ir?
