--- Comment #1 from Chuanqi Xu <yedeng.yd at linux.alibaba.com> ---
To generate module interface, we need to use `-Xclang -emit-module-interface`
to generate it. And when we need to importing it, we need to set
`-fprebuilt-module-path`. See an example from
https://lists.llvm.org/pipermail/cfe-dev/2021-October/069156.html.
So I think this bug should be invalided.
