Hi all,
I noticed that Conan Center provides newer EMSDK versions (3.1.72 and 3.1.73), but both versions fail when running Binaryen optimizations (wasm-opt). The error message indicates that wasm-opt does not recognize certain options, specifically:

Unknown option '--enable-bulk-memory-opt'
Or
Unknown option '--enable-call-indirect-overlong'

Error log:

link:DEBUG: using binaryen
Unknown option '--enable-call-indirect-overlong'
em++: error: '/home/l146/.conan2/p/emsdkc9782d7aefec5/p/bin/upstream/bin/wasm-opt --strip-target-features --post-emscripten --pass-arg=post-emscripten-side-module -O3 --low-memory-unused --asyncify --pass-arg=asyncify-relocatable --pass-arg=asyncify-propagate-addlist [email protected]_,env.asyncjs,.fd_sync,.emscripten_promise_await,._dlopen_js,.emscripten_idb_load,.emscripten_idb_store,.emscripten_idb_delete,.emscripten_idb_exists,.emscripten_idb_clear,.emscripten_idb_load_blob,.emscripten_idb_store_blob,.emscripten_sleep,.emscripten_wget_data,.emscripten_scan_registers,.emscripten_lazy_load_code,._load_secondary_module,.emscripten_fiber_swap,*.SDL_Delay --pass-arg=directize-initial-contents-immutable --no-stack-ir libRFWARM.wasm -o libRFWARM.wasm --mvp-features --enable-threads --enable-bulk-memory --enable-call-indirect-overlong --enable-multivalue --enable-mutable-globals --enable-reference-types --enable-sign-ext' failed (returned 1)

This issue is resolved in EMSDK 3.1.74 or newer (tested with 3.1.74 and 4.0.2), where the options are correctly recognized.

A similar issue was reported here: iree-org/iree#19425.

Would it be possible to update the Conan Center package to use a newer EMSDK version (suggest 4.0.2)? This would prevent similar build failures for users relying on the prebuilt versions.

Thanks!
