"""Target description and codegen module.

TVM uses JSON-based target configuration. Targets can be constructed via:

- A config dictionary: ``Target({"kind": "cuda", "arch": "sm_80"})``
- A tag name: ``Target("nvidia/nvidia-a100")``
- A tag with overrides: ``Target({"tag": "nvidia/nvidia-a100", "l2_cache_size_bytes": 12345})``
- A kind name: ``Target("cuda")``

Use ``target.attrs["key"]`` to access target attributes such as
``"arch"``, ``"max_num_threads"``, ``"mcpu"``, ``"libs"``, etc.

Use :py:func:`tvm.target.list_tags` to list all available target tags,
and :py:func:`tvm.target.register_tag` to register new tags.
