            Bug ID: 46836
           Summary: OpenMP nvptx64 codegen is broken
           Product: OpenMP
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: release blocker
          Priority: P
         Component: Clang Compiler Support
          Assignee: unassignedclangbugs at nondot.org
          Reporter: protze at itc.rwth-aachen.de
                CC: llvm-bugs at lists.llvm.org

https://reviews.llvm.org/D83268 broke compilation of previously working code.

I added the following to
`openmp/libomptarget/test/offloading/offloading_success.c`:


+// RUN: %libomptarget-compile-run-and-check-nvptx64-nvidia-cuda


which results in 


# command stderr:
ptxas offloading_success-openmp-nvptx64-nvidia-cuda.s, line 173; error   : Call
has wrong number of parameters
ptxas fatal   : Ptx assembly aborted due to errors
clang-12: error: ptxas command failed with exit code 255 (use -v to see
invocation)


There is more details in above linked review. I would consider this a release
blocker. Either revert the patch or cherry-pick a fix.
