This directory contains common library components for AOTI (Ahead-of-Time Inference) driven backends in ExecuTorch, not a standalone backend.

The code in this directory provides shared functionality and utilities that are used by actual AOTI-driven backends such as:

• CUDA backend - Uses AOTI for GPU acceleration
• Other AOTI-powered backends

• common_shims.cpp/h - Common shim functions that bridge ExecuTorch tensor operations with AOTI requirements
• aoti_model_container.cpp/h - Model container functionality for AOTI models
• utils.h - Utility functions and type definitions
• tests/ - Unit tests for the common functionality

This library is intended to be used as a dependency by actual AOTI backend implementations. It is not a backend that can be used directly for model execution.

For example backend implementations that use this common library, see:

• executorch/backends/cuda/ - CUDA AOTI backend

The common library components are built as part of the AOTI backend build process. See the TARGETS file for build configurations.
