CUDA program to LLVM

[ghost]

Hi, I was trying to convert the official CUDA Sample vectorAdd program to mlir and llvm using Polygeist. The Polygeist was built using these commands:

LLVM-PROJECT BUILD cmake -G Ninja ../llvm \ -DLLVM_ENABLE_PROJECTS="clang;mlir;lld" \ -DLLVM_ENABLE_RUNTIMES="compiler-rt;libcxx;libcxxabi" \ -DLLVM_TARGETS_TO_BUILD="X86;NVPTX" \ -DMLIR_ENABLE_CUDA_RUNNER=ON \ -DMLIR_ENABLE_EXECUTION_ENGINE=ON \ -DLLVM_ENABLE_RTTI=ON \ -DLLVM_ENABLE_ASSERTIONS=ON \ -DCMAKE_BUILD_TYPE=Debug \ -DCMAKE_CUDA_COMPILER=/usr/local/cuda/bin/nvcc \ -DCMAKE_CUDA_TOOLKIT_INCLUDE_DIRECTORIES=/usr/local/cuda/include \ -DCLANG_LINKER_WRAPPER_ENABLED=OFF

ninja

POLYGEIST BUILD cmake -G Ninja .. \ -DMLIR_DIR=$PWD/../llvm-project/build/lib/cmake/mlir \ -DCLANG_DIR=$PWD/../llvm-project/build/lib/cmake/clang \ -DPOLYGEIST_ENABLE_CUDA=1 \ -DCMAKE_CUDA_COMPILER=/usr/local/cuda/bin/nvcc \ -DCUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda \ -DLLVM_ENABLE_ASSERTIONS=ON \ -DLLVM_ENABLE_RTTI=ON \ -DCMAKE_BUILD_TYPE=Debug \ -DCMAKE_CUDA_TOOLKIT_INCLUDE_DIRECTORIES=/usr/local/cuda/include

ninja

The program converts to mlir without any errors using: ./cgeist --immediate -cuda-path=/usr/local/cuda -I/usr/local/cuda/include -I/usr/lib/gcc/x86_64-linux-gnu/11/include --resource-dir=/local/Polygeist/llvm-project/build/lib/clang/18 -I/local/cuda-samples/Common --cuda-gpu-arch=sm_86 vectorAdd.cu The ouput is MLIR_trace.txt

But when I directly try to convert the using: ./cgeist -cuda-path=/usr/local/cuda -I/usr/local/cuda/include -I/usr/lib/gcc/x86_64-linux-gnu/11/include --resource-dir=/local/Polygeist/llvm-project/build/lib/clang/18 -I/local/cuda-samples/Common --cuda-gpu-arch=sm_86 vectorAdd.cu The ouput is LLVM_trace.txt

Are there any steps that I am missing? What can be the issue? Thanks!
