Hi,
My configuration is below:
cmake -GNinja -DLLVM_ENABLE_LLD=ON -DLLVM_ENABLE_THREADS=OFF
-DLLVM_ENABLE_LIBCXX=ON -DCMAKE_BUILD_TYPE=Release
-DGCC_INSTALL_PREFIX=/home/usr4/c74014i/opt/gcc-7.5.0/
-DLIBOMPTARGET_ENABLE_DEBUG=ON
-DCMAKE_INSTALL_PREFIX=$HOME/opt/clang/${today} -DCMAKE_C_COMPILER=clang
-DCMAKE_C_FLAGS="" -DCMAKE_CXX_COMPILER=clang++
-DCMAKE_CXX_FLAGS=""
-DLLVM_ENABLE_PROJECTS="clang;openmp;lld;libcxx;libcxxabi;compiler-rt;libunwind"
-DCLANG_OPENMP_NVPTX_DEFAULT_ARCH=sm_60
-DLIBOMPTARGET_NVPTX_COMPUTE_CAPABILITIES=60
-DLLVM_TARGETS_TO_BUILD="all"
/tmp/llvm-project/llvm

but did not help my case:

[...]
