Move the PyGC_Head structure and the following private macros to the internal C API: * _PyGCHead_FINALIZED() * _PyGCHead_NEXT() * _PyGCHead_PREV() * _PyGCHead_SET_FINALIZED() * _PyGCHead_SET_NEXT() * _PyGCHead_SET_PREV() * _PyGC_FINALIZED() * _PyGC_PREV_MASK * _PyGC_PREV_MASK_COLLECTING * _PyGC_PREV_MASK_FINALIZED * _PyGC_PREV_SHIFT * _PyGC_SET_FINALIZED() * _PyObject_GC_IS_TRACKED() * _PyObject_GC_MAY_BE_TRACKED() * _Py_AS_GC(o) Keep the private _PyGC_FINALIZED() macro in the public C API for backward compatibility with Python 3.8: make it an alias to the new PyObject_GC_IsFinalized() function. Move the SIZEOF_PYGC_HEAD constant from _testcapi module to _testinternalcapi module.
