Describe the bug
Cannot compile simple Cxx interop hello world project, when -target wasm32-unknown-wasi is set.
This works:
swiftc helloword.swift -o ubu.wasm -enable-experimental-cxx-interop -I ./helloCxx -Xfrontend -validate-tbd-against-ir=none
This doesn't work:
swiftc -target wasm32-unknown-wasi helloword.swift -o ubu.wasm -enable-experimental-cxx-interop -I ./helloCxx -Xfrontend -validate-tbd-against-ir=none
