Simplifying command line options is a different topic and we have not agreed upon how to do the simplification. In general, that is unrelated to this broken test case. But it can probably be fixed later with a separate patch. > Our plan was always to support SDLs using -l and -L options, as described in > Greg Rodgers's presentation about static device libraries > <https://www.youtube.com/watch?v=3FsYwEhtCaM> in last year's LLVM-CTH > Workshop.

To me, supporting both -L/-l and libXXX.a are both required for static libraries. It is not reasonable to request users to use one way not the other. AOMP had no issue working in both ways. > PS: We (mulit-company OpenMP-dev meetings) have been tracking this feature > for a while and we would very much like it to be picked for llvm-13. Although we wanted to deliver this feature to users, I don't think we should tell users that linking static archive works with the current quality. So in my view, It is not suitable to backport it o 13. This patch is good. It makes part of the static linking feature work but we can not claim "Static Device Libraries" is fully working. So please update the tile and also in the description saying what is working and what is not. Also need a test case for nvptx64. In addition, I'd like to see commitment of addressing both above failed test cases before accepting this patch to help incremental development. by the way, I found offload to x86 with static linking doesn't work with -L. -lmylib https://github.com/ye-luo/openmp-target/blob/master/tests/linking/link_static_fat_bin/compile-x86.sh I think this can also be addressed separately. FYI, AOMP happily makes it working.
