@kiranchandramohan I discussed the current approach with @skatrak today. When
trying to implement the mapper lowering for the map clause, it became apparent
that we need to add the `declMapperOp` name to the `SymbolTable`. As such, we
would also need to hoist the `declareMapperOp` to the `ModuleOp`.
I am however struggling with name mangling the `declMapperOp` such that scoping
information is preserved, and we don't have clashing `declMapperOps` from
different nested scopes with the same name.
Take the following example:
```
program my_prog
type my_type
integer :: num
end type
!$omp declare mapper (my_mapper : my_type :: my_var) map (my_var)
contains
subroutine test
type(my_type) :: xyz
!$omp target enter data map(mapper(my_mapper), to: xyz)
end subroutine test
end program my_prog
```
Here after mangling the, `declMapperOp` symbol name becomes `_QQFmy_mapper`.
But when trying to mangle the name that occurs in the mapClause before lookup
results in `_QQFFtestmy_mapper`.
Do you know any mechanism in Fortran lowering that could help resolve this
issue?
