ye-luo added a comment.

Do I must use llvm-ar/ranlib  or system ar/ranlib is OK?

1. existing use case breaks

Use https://github.com/ye-luo/openmp-target/blob/master/tests/math/modf.cpp
$ clang++ -fopenmp -fopenmp-targets=nvptx64 -Xopenmp-target=nvptx64 -march=sm_80 modf.cpp  # still OK
$ clang++ -fopenmp -fopenmp-targets=nvptx64 -Xopenmp-target=nvptx64 -march=sm_80 modf.o 
clang-14: warning: Unknown CUDA version. version.txt: 11.0.228. Assuming the latest supported version 10.1 [-Wunknown-cuda-version]
nvlink fatal   : Could not open input file '/tmp/modf-0bf89b.cubin'
clang-14: error: nvlink command failed with exit code 1 (use -v to see invocation)

2. could you make my test case working?

https://github.com/ye-luo/openmp-target/tree/master/tests/link_static_fat_bin
both compile-amd.sh and compile.sh doesn't work for me.
