The issue is that clang front-end does not support -stdlib=libstdc++ for wasm32-wasi. It always adds -lc++abi toggle. Is that possible to disable this and use -lsupc++?

That seems like a question about using clang, so off topic here, but I
would try -nostdlib -lsupc++

Probably We need to tell clang to support -stdlib=libstdc++ for wasm? And nathan is able to modify the clang source code directly

Hello clang and llvm devs. Can you enable -stdlib=libstdc++ for wasm32-wasi? I have successfully built libstdc++ with clang, targeting wasm32-wasi. Problem is clang does not support this for that target. Options like -nostdinc++ will end up conflict with -lc++abi since clang always adds -lc++abi to the compilation command.
I know GCC itself does not support webassembly, but Libstdc++ can be built.
Thank you
