[CUDA] CTS atomic tests fail with unresolved extern function '_Z22__spirv_AtomicExchangePU3AS1fN5__spv5Scope4FlagENS1_19MemorySemanticsMask4FlagEf' #5096
Description
Describe the bug
CTS atomic tests fail with unresolved extern function '_Z22__spirv_AtomicExchangePU3AS1fN5__spv5Scope4FlagENS1_19MemorySemanticsMask4FlagEf' on Linux with CUDA backend
To Reproduce
- Get SYCL with CUDA support (GSG) and KhronosGroup/SYCL-CTS@b61c52a
- Build CTS tests
cd SYCL-CTS
mkdir build && cd build
cmake -G "Ninja" -DSYCL_IMPLEMENTATION=Intel_SYCL -DINTEL_SYCL_ROOT=<path to built sycl> -DOpenCL_LIBRARY=<path to built sycl>/lib/libOpenCL.so -DOpenCL_INCLUDE_DIR=<path to built sycl>/include/sycl -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_FLAGS_RELEASE="-fsycl -fsycl-unnamed-lambda -Wno-deprecated-declarations" -DINTEL_SYCL_FLAGS="-fsycl-device-code-split=per_kernel" -DCMAKE_EXE_LINKER_FLAGS=" -Wl,-no-relax " -DINTEL_SYCL_TRIPLE=nvptx64-nvidia-cuda -DSYCL_CTS_ENABLE_OPENCL_INTEROP_TESTS=Off -DSYCL_CTS_ENABLE_DOUBLE_TESTS=On -DSYCL_CTS_ENABLE_HALF_TESTS=On ..
