[llvm-dev] LLVM/CUDA generate LLVM IR

[Gurunath Kadam via llvm-dev]

So for a c program we do:

        clang -O3 -emit-llvm hello.c -c -o hello.bc

But how to generate an LLVM IR when working with CUDA.

for normal compilation:
         clang++ axpy.cu -o axpy --cuda-gpu-arch=<GPU arch> -L<CUDA install
path>/<lib64 or lib> -lcudart_static -ldl -lrt -pthread

I tried adding -S -emit-llvm and changed the output file name, but I keep
getting following error:

clang++:
/stor/gakadam/llvm_projects/llvm/tools/clang/lib/Driver/Driver.cpp:1618:
virtual
{anonymous}::OffloadingActionBuilder::DeviceActionBuilder::ActionBuilderReturnCode
{anonymous}::OffloadingActionBuilder::CudaActionBuilder::getDeviceDepences(clang::driver::OffloadAction::DeviceDependences&,
clang::driver::phases::ID, clang::driver::phases::ID,
{anonymous}::OffloadingActionBuilder::DeviceActionBuilder::PhasesTy&):
Assertion `CurPhase < phases::Backend && "Generating single CUDA "
"instructions should only occur " "before the backend phase!"' failed.

I tried several combinations but no avail!

Any suggestions?

Thank you.

Sincerely,
Guru
