There was a problem hiding this comment.
We might want to explain in the PR description why this is needed.
Something along the lines of "Any symbol that the compiler might generate at bitcode compile time either need to be unconditionally included at LTO time, or not built as LTO. This is because LTO object files cannot be added to the link after LTO time".
