            Bug ID: 38710
           Summary: static functions are not emitted as implicitly
                    'declare target'
           Product: OpenMP
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Clang Compiler Support
          Assignee: unassignedclangbugs at nondot.org
          Reporter: hahnjo at hahnjo.de
                CC: llvm-bugs at lists.llvm.org

$ clang -fopenmp -fopenmp-targets=nvptx64-nvidia-cuda target-implicit-static.c
nvlink error   : Undefined reference to 'implicit' in
'<<<>>>/target-implicit-static-ddf1bd.cubin'
clang-7: error: nvlink command failed with exit code 255 (use -v to see
invocation)

$ cat target-implicit-static.c 
static void implicit() { }

int main()
{
  #pragma omp target
  {
    implicit();
  }

  return 0;
}

Removing  the static keyword "fixes" compilation.
