### C code

WASI SDK defines several built-in macros. You can dump a full list of built-ins
with ``/path/to/wasi-sdk/bin/clang -dM -E - < /dev/null``.
The following built-in macros identify WebAssembly targets and environments.
For WASI SDK, you can dump a full list of built-ins with
`/path/to/wasi-sdk/bin/clang -dM -E - < /dev/null`.

* WebAssembly ``__wasm__`` (also ``__wasm``)
* wasm32 ``__wasm32__`` (also ``__wasm32``)
* wasm64 ``__wasm64__``
* WASI ``__wasi__``
#### Shared with Emscripten

- WebAssembly target: `__wasm__` (also `__wasm`)
- wasm32 target: `__wasm32__` (also `__wasm32`)
- wasm64 target: `__wasm64__`

#### Unique to WASI

- WASI environment: `__wasi__`
