Consider the following program.

  int c;

#pragma omp target data map(tofrom: c)
{
  #pragma omp target nowait
  {
      c = 2;
  }
}
  return c;
}

When compiled with clang -cc1 -triple x86_64-unknown-linux-gnu -emit-llvm-bc -debug-info-kind=standalone -fopenmp -fopenmp-targets=amdgcn-amd-amdhsa, it fails with the following errors.
