Hello, I'm working on modularizing my project.
While looking into various ways to solve ABI compatibility issues, I came across an Underscore Attribute called @_originallyDefinedIn.
It seems like this could solve my problem, so I tried following the guide, but it appears that the Swift compiler flags -Xfrontend -emit-ldadd-cfile-path -Xfrontend /tmp/t.c mentioned in the documentation no longer work.
I'm also having considerable difficulty finding information about -emit-ldadd-cfile-path. Is there anyone who might be able to help?
