6 * Support for running Halide-compiled Wasm code in-process.
7 * Bindings for parameters, extern calls, etc. are established and the
8 * Wasm code is executed. Allows calls to realize to work
9 * exactly as if native code had been run, but via a JavaScript/Wasm VM.
10 * Currently, only the WABT interpreter is supported.

Halide::LinkageType::Internal
@ Internal
Not visible externally, similar to 'static' linkage in C.
Halide::cast
Internal::ConstantInterval cast(Type t, const Internal::ConstantInterval &a)
