This pull request refactors how function pointers for AOTI model container operations are managed and loaded in the CUDA backend. Instead of relying on global/static function pointers, function pointers are now stored per-instance in the
AOTIDelegateHandlestructure. This change enables safe handling of multiple shared libraries within the same process and improves encapsulation and maintainability.Refactoring function pointer management:
aoti_model_container.cppandaoti_model_container.h, and moved them into theAOTIDelegateHandlestruct as per-instance members. [1] [2] [3]CUDA backend updates:
cuda_backend.cpp) to load function pointers into eachAOTIDelegateHandleinstance using a newload_function_pointers_into_handlemethod, replacing the previous global symbol registration logic. All calls to model container functions now use the handle's member function pointers. [1] [2] [3] [4] [5]Build system adjustments:
aoti_model_container.cppfrom the build targets and library sources, as global function pointer definitions are no longer needed. [1] [2]
