This folder contains generated sources for the lazy torchscript backend.
The main input file that drives which operators get codegen support for torchscript backend is ../../../../aten/src/ATen/native/ts_native_functions.yaml
The code generator lives at torchgen/gen_lazy_tensor.py.
It is called automatically by the torch autograd codegen (tools/setup_helpers/generate_code.py) as a part of the build process in OSS builds (CMake/Bazel) and Buck.
External backends (e.g. torch/xla) call gen_lazy_tensor.py directly, and feed it command line args indicating where the output files should go.
