Looks good, but you also need to add that `|| flags.test(Fortran::semantics::Symbol::Flag::OmpCopyIn)` in `Bridge.cpp`, to handle the copy of unallocated variables. WIthout it the test program below crashes.

```f90
program main
  integer, allocatable, save :: a
  !$omp threadprivate(a)

  !$omp parallel copyin(a)
    a = 1
  !$omp end parallel
end program
```
