Currently, only OpenMP Threadprivate Flag is resolved in semantic analysis stage. https://github.com/llvm/llvm-project/blob/c1b9672534cdc798f2a7ba6b7b6be85dea0d8a5a/flang/lib/Semantics/resolve-directives.cpp#L483-L484  https://github.com/llvm/llvm-project/blob/c1b9672534cdc798f2a7ba6b7b6be85dea0d8a5a/flang/lib/Semantics/resolve-directives.cpp#L213

What can be in the clause of the declarative directive is case-by-case. For OpenMP Threadprivate directive, the module name, procedure name cannot be in the clause. If a threadprivate directive that specifies a common block name appears in one program unit, then such a directive must also appear in every other program unit that contains a COMMON statement that specifies the same name. So, no need to export common block for Threadprivate directive.
