            Bug ID: 51649
           Summary: OpenMPOpt hit assertion when using
                    --cuda-noopt-device-debug
           Product: OpenMP
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Clang Compiler Support
          Assignee: unassignedclangbugs at nondot.org

I tried to pass --cuda-noopt-device-debug to Clang to influence ptxas
invocation by clang and hit this assertion.

Using miniQMC.
cmake -D CMAKE_CXX_COMPILER=clang++ -D ENABLE_OFFLOAD=1 -D USE_OBJECT_TARGET=ON
-DCMAKE_CXX_FLAGS="-g --cuda-noopt-device-debug" ..


clang-14:
/home/yeluo/opt/llvm-clang/llvm-project/llvm/lib/Transforms/IPO/OpenMPOpt.cpp:2880:
virtual void {anonymous}::AAKernelInfoFunction::initialize(llvm::Attributor&):
Assertion `(KernelInitCB && KernelDeinitCB) && "Kernel without
__kmpc_target_init or __kmpc_target_deinit!"' failed.
PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash
