This is equivalent to the existing `import_name` and `import_module` attributes which control the import names in the final wasm binary produced by lld. This maps the existing This attribute currently requires a string rather than using the symbol name for a couple of reasons: 1. Avoid confusion with static and dynamic linking which is based on symbol name. Exporting a function from a wasm module using this directive is orthogonal to both static and dynamic linking. 2. Avoids name mangling. Differential Revision: https://reviews.llvm.org/D70520
