wasm-bindgen Files

Changed

• Emscripten output now hoists every clean export (free functions, classes, enums, plus their finalization registries and string-enum tables) out of the $initBindgen init closure into its own top-level addToLibrary symbol and self-registers it into EXPORTED_FUNCTIONS. emscripten then emits the clean API (add, Counter, ...) as named ESM exports under -sMODULARIZE=instance and as Module.<name> properties (via each symbol's __postset) in factory mode, with no extra sidecar files. Namespaced exports are reached through their namespace root (e.g. app), assembled in the root symbol's __postset. User module/inline-js imports are now wired as addToLibrary shims (they were previously dropped, since emcc resolves imports only against env), and their ESM-imported bindings are __wbg_-prefixed to avoid colliding with emcc runtime names such as Module/HEAP8. #5210

Fixed

• The descriptor interpreter now follows emscripten invoke_* trampolines. emscripten's exception/longjmp lowering rewrites direct calls into indirect calls through the function table wrapped in imported invoke_*(fnptr, ..args) helpers, including the describe helpers a descriptor function must reach. The interpreter resolves fnptr against the reconstructed function table, forwards the trailing arguments, and evaluates the surrounding "did it throw?" control flow (if/else, loop, br_table), so descriptors are interpreted correctly on emscripten builds with unwinding/longjmp enabled. #5215

• Relaxed alignment requirement for 8-byte types. #5204
