i may be misinterpreting your reply. you're saying there is no need for
2 because we use .def files?

strictly speaking when exporting C symbols this is true. so yes, we
could introduce only __rte_import and not bother with __rte_export.

is that what you meant?

i don't have any objection to just __rte_import alone but it is
mandatory for data symbols.
