modules After https://github.com/llvm/llvm-project/pull/86912, for the following example, ``` export module A; export import B; ``` The generated BMI of `A` won't change if the source location in `A` changes. Further, we plan avoid more such changes. However, it is slightly problematic since `export import` should propagate all the changes. So this patch adds a signature to the BMI of C++20 modules so that we can propagate the changes correctly.
